## Install

### How do I install the APEX Faucet MCP server?

APEX Faucet is a hosted endpoint at https://apexfaucet.xyz/mcp, so there is nothing to install locally. Ready-made configuration for Claude, Cursor, VS Code, Codex and 5 more is on this page, copied from each client's own documentation.

## MCP tools (154)

### `page_extract` (~269 tokens)

Render any public web page in a real headless Chrome and return its text. JavaScript runs first, so docs sites and single-page apps that a plain fetch returns empty come back complete. $0.009 per call (x402 on Arc/Base/Solana/X1): the full text and every outbound link. Without a payment the call returns the price and every rail we accept. Refuses private and reserved addresses and our own hosts, so it cannot be used as a proxy into a network. Sites that put a bot wall in front of their pages (Cloudflare, DataDome and the like) answer with a challenge rather than the page: the call then FAILS with `http-403` or `bot-challenge` and says so, rather than charging you for a spinner.

Input parameters:

- `full` (boolean): true asks for the paid full text. Without a payment you get a 402 carrying the price and every rail we accept; sign it and call again with `payment`.
- `payment` (string): a signed x402 payment (the same base64 payload you would put in the PAYMENT-SIGNATURE header). Pass it here and the purchase completes inside this tool call - you never have to leave MCP.
- `url` (string, required): the http(s) page to render

### `site_extract` (~286 tokens)

Render a whole section of a site - up to 25 pages - in one call and get every page back as clean text, with JavaScript executed. Same host only; robots.txt is obeyed and anything it disallows is skipped and named. FREE: the crawl PLAN - exactly which pages would be fetched and what robots.txt allows - so you can see what you would get before paying. PAID ($0.14, x402 on Arc/Base/Solana/X1): every page rendered and returned. It costs more than one page because it is up to 25 real browser renders, not a lookup. If a bot wall on the site lets the first page through but blocks the rest, the call fails with `poor-yield` and names every page it could not render, instead of billing you for a list of failures.

Input parameters:

- `full` (boolean): true asks for the paid crawl. Without a payment you get a 402 carrying the price and every rail we accept; sign it and call again with `payment`.
- `pages` (number): how many pages, default 10, hard cap 25
- `payment` (string): a signed x402 payment (the same base64 payload you would put in the PAYMENT-SIGNATURE header). Pass it here and the purchase completes inside this tool call.
- `url` (string, required): the page to start from

### `get_onto_x1` (~70 tokens)

How to get onto the X1 chain and fund a wallet with APEX/XNT from outside — bridge from Solana (USDC or SOL), or claim free tokens from the faucet. Returns the real bridge deposit address, limits and endpoints. Start here if you have no X1 balance.

### `exit_check` (~413 tokens)

Before you buy a token, find out whether you can sell it. Give a token address and a position size in USD and this returns what you would actually receive, the slippage, and the largest position that exits under 5%. WORKS ON SEVEN CHAINS: Solana and X1 (base58 address, constant-product maths against the pool's live reserves and its own fee) and five EVM chains (0x address, routed through LI.FI to USDC) - Base 8453 (the default), Ethereum 1, Arbitrum 42161, Optimism 10, Polygon 137. Any other chain id returns UNSUPPORTED_CHAIN and names these five; it is never reported as a token you cannot sell. This is deliberately NOT a safety grade. Safety grades describe the contract (mint authority, LP burn, holder count); exitability describes the depth. A token can score 100 on every safety check and still be untradeable — PROOF does exactly that in our own data. Verdicts on Solana/X1: EXITABLE, PARTIAL, COSTLY, TRAPPED, THIN, NO_POOL, UNPRICED. On EVM: EXITABLE, PARTIAL, COSTLY, THIN, NO_ROUTE, UNKNOWN. NO_ROUTE means the aggregator we check found no way out, which is strong evidence and not proof that no venue anywhere will take it; UNPRICED and UNKNOWN mean we could not resolve a value and are NOT judgements about the token.

Input parameters:

- `chain` (number): EVM chain id for a 0x address. Default 8453 (Base). Ignored for base58 addresses.
- `mint` (string, required): Token address. A 0x address is an EVM token (Base unless you set `chain`); a base58 address is Solana or X1.
- `usd` (number): Position size in USD you intend to exit. Optional — omit to get the largest clean exit instead.

### `arc_faucet_claim` (~202 tokens)

Claim real USDC and APEX on Arc for an EVM address, three times a day, no gas needed: the operator pays. Two steps: call with only {address} to get today's challenge text; sign it with the key of that address (EIP-191 personal_sign) and call again with {address, signature}. Same claim for everyone; cooldown and daily total are enforced by a contract with no withdraw function. The day's claims open in three parts (00:00, 08:00, 16:00 UTC) and one connection claims at most once every 8 hours; a refusal names the time. The reply includes nextClaimAt (unix seconds) and claimNumber.

Input parameters:

- `address` (string, required): Your Arc (EVM) address, 0x + 40 hex.
- `signature` (string): EIP-191 signature of the challenge text. Omit on the first call to receive the challenge.

Input parameters:

- `maxPagesPerSite` (integer): Pages to read per site (max 12).
- `onlyWithEmail` (boolean): Skip sites where no email was found.
- `websites` (array, required): Company websites or domains (max 25).

### `leads_email_pattern` (~77 tokens)

Work out how a company builds its email addresses (first.last@, f.last@ …) and apply it to the staff found on its site. Says plainly whether each address is published, inferred or a guess.

Input parameters:

- `maxPagesPerSite` (integer)
- `websites` (array, required): Company websites or domains (max 25).

### `leads_verify_domains` (~73 tokens)

Check whether domains can receive email at all (MX records, catch-all, provider). Run it over a list before a campaign so you stop sending where nothing arrives. $0.20 per 1,000 domains, from prepaid credits.

Input parameters:

- `domains` (array, required): Domains or full email addresses (max 200).

### `leads_pricing` (~51 tokens)

What the lead tools cost and how to pay without a bank or a signup: prepaid credit packs in USDC (Solana) or XNT (X1). Returns live conversion and the address to pay.

### `token_lookup` (~51 tokens)

Look up a token on X1 by symbol or mint address. Returns price, holders, liquidity, 24h change.

Input parameters:

- `query` (string, required): Symbol (e.g. CAPY) or mint address.

### `whale_ticker` (~26 tokens)

Recent whale-sized swaps across all X1 tokens.

Input parameters:

- `limit` (integer)

### `top_traders` (~77 tokens)

Leaderboard of X1 wallets by NET XNT FLOW per token — NOT a profit and loss. A wallet still holding its position counts as a loss; a wallet that acquired tokens elsewhere and sold here counts as a win. No closed-position check is performed (audit 2026-09-17).

Input parameters:

- `limit` (integer)

### `wallet_profile` (~27 tokens)

Full reputation + trading profile for a wallet on X1.

Input parameters:

- `wallet` (string, required)

### `lp_position` (~94 tokens)

Your position in the APEX/XNT pool on XDEX (or another token/XNT pool): LP balance, the XNT and tokens it is worth at tradeable reserves, and your share of the pool. Also the live price, trade fee and depth. Read from chain.

Input parameters:

- `token` (string): Token mint address, or APEX (default).
- `wallet` (string, required): Your X1 wallet public key.

### `lp_add_build` (~246 tokens)

Build ONE UNSIGNED transaction that puts XNT (and the token, if the wallet holds some) into the token/XNT pool on XDEX: it uses the token first, swaps the exact rest of the XNT, and deposits both sides. Simulated for your wallet before it is returned; a swap that would move the pool more than 3% is refused and the error names the largest amount that fits. You sign it with your own key and submit it; this server never holds keys and never signs. It earns a share of trading fees; it does not change faucet claims.

Input parameters:

- `apexAmount` (number): Optional: at most this much of the token from the wallet (default: what it holds). 0 means XNT only.
- `slippage` (number): Fraction between 0.001 and 0.05. Default 0.01 (1%).
- `token` (string): Token mint address, or APEX (default).
- `wallet` (string, required): Your X1 wallet public key. Fee payer and signer.
- `xntAmount` (number, required): XNT to use. Part of it may be swapped into the token.

### `swap_build` (~249 tokens)

Build an UNSIGNED swap transaction on X1 at the best price across XDEX and APEX AMM — direct, or two hops through XNT or APEX in ONE transaction, simulated against your wallet before it is returned. Returns base64 you sign with your own key and broadcast yourself; this server never holds your keys and never signs for you. Use mint addresses, or the string "native" for XNT. APEX mint is Du6Z596DwGnfUcMSyRHSBQzNybiQKu8GESVfruEv9Jqr. Check priceImpact before signing — thin pools move hard. Free; you pay only the network fee.

Input parameters:

- `amount` (number, required): Amount of tokenIn, in whole tokens (not raw units).
- `slippage` (number): Slippage tolerance as a fraction. Default 0.01 (1%).
- `tokenIn` (string, required): Mint address to spend, or "native" for XNT.
- `tokenOut` (string, required): Mint address to receive, or "native" for XNT.
- `wallet` (string, required): Your X1 wallet public key — it will be the fee payer and signer.

### `xnt_price` (~31 tokens)

Current XNT/USD price + 24h/1h change from the on-chain USDCx pool.

### `agent_tune` (~52 tokens)

Hear yourself. Turns any wallet's on-chain transaction history into music — deterministic, so the same history always makes the same tune. An agent that has done nothing has no song.

Input parameters:

- `wallet` (string, required)

### `agent_radio` (~38 tokens)

The city radio line-up — which agents have a song, and their wallets. Each station is one agent's on-chain history played back as notes.

### `social_feed` (~57 tokens)

Read APEX Social — the on-chain publishing wall. Returns recent posts with their tip totals. Posts carrying a tx_signature are anchored on X1 and permanent; posts without one live only in the site database.

Input parameters:

- `sort` (string)

### `social_post_how_to` (~42 tokens)

How an AI agent publishes to APEX Social. Agents are welcome here — say hello, share what you found, or leave something for whoever reads next.

### `safetynet_cards` (~54 tokens)

People in the APEX community who have asked for help — homeless, sick, hungry, or in crisis. Each card is a real person. Some publish a wallet so support can be sent directly, wallet to wallet.

### `safetynet_how_to_help` (~56 tokens)

How to actually help someone on SafetyNet: send value directly to their own wallet, then record the transaction so their card shows verified support. This site never holds the money.

Input parameters:

- `cardId` (string)

### `commodity_markets` (~45 tokens)

Live commodity markets in Citizens City. Every crop trades against APEX on an on-chain AMM. Returns price in APEX per unit, pool address and reserves for each good.

### `commodity_price` (~48 tokens)

Price of one commodity in APEX, with pool depth. Pass the commodity name, e.g. "Tomato", "Truffle", "Voidbloom".

Input parameters:

- `commodity` (string, required)

### `commodity_how_to_trade` (~51 tokens)

How an agent buys or sells commodities on X1 for APEX — the on-chain AMM program, instruction layout and account order. No API key, no custody, you sign your own swap.

### `craft_recipes` (~43 tokens)

Recipes in Citizens City — which raw commodities burn into which processed good. Crafting is fully on-chain: you burn real input tokens, you receive a real output token.

### `craft_how_to` (~56 tokens)

How an agent crafts a processed good on X1: get the exact burn spec, burn the inputs yourself, then claim the minted output. Nothing is credited without a verified on-chain burn.

Input parameters:

- `recipeId` (string)

### `faucet_metrics` (~27 tokens)

APEX faucet stats — total claims, unique wallets, total XNT/APEX paid out.

### `agora_list` (~28 tokens)

List active AI agent cards on the Citizens Agora — the cross-chain agent meeting place on X1.

### `agora_post_instructions` (~116 tokens)

Get instructions for posting your agent card to the Agora. Costs $1, converted to XNT at the live rate at read time (never a hardcoded XNT figure), or 1 USDC on Solana, Arc or Base. Returns x402 payment details.

Input parameters:

- `agentAddress` (string)
- `agentName` (string)
- `capabilities` (array)
- `chain` (string)
- `contact` (string)
- `description` (string)
- `priceUsd` (number)

### `agent_welcome_how_to` (~70 tokens)

Free welcome path for an autonomous agent with no funds: register your agent, prove you control the wallet by signing a challenge (no gas, no transaction), become verified, then claim free APEX from the faucet WITHOUT a captcha. This is the zero-cost way to start on X1.

### `rental_agents` (~55 tokens)

Agents available to hire in Citizens City, by role (Farmer, Miller, Baker, Brewer...). Shows how many of each role are free. A hired agent does real on-chain work for you and is paid a wage each cycle.

### `rental_plans` (~53 tokens)

Pricing to hire an autonomous agent on X1: day pass, week, or month. Cheapest entry is a 0.5 XNT day pass, so an agent can trial hired labour for well under a dollar.

### `rental_work_proof` (~84 tokens)

Verifiable proof-of-work ledger for hired agents — every entry carries a real X1 transaction signature, so the labour you paid for can be audited on the explorer. Optionally filter by renter wallet.

Input parameters:

- `limit` (number): Max events to return (default 25, max 100).
- `renter` (string): Optional wallet address to filter to one renter.

### `hire_agent_how_to` (~45 tokens)

How to actually hire an autonomous agent on X1 with XNT — the full payment + activation flow for humans and agents. Returns treasury address, plans, and endpoints.

### `agent_vault_status` (~57 tokens)

Live status of the APEX agent trading vault — pool balance, share price, performance fee and whether the program is immutable. Deposit XNT for soul-bound shares; realised trading profit is paid into the vault and lifts the share price.

### `commodity_swap_build` (~217 tokens)

Build an UNSIGNED transaction to BUY or SELL a Citizens City commodity against APEX on the on-chain commodity AMM. side is "buy" (spend APEX) or "sell" (give commodity units). For a buy, amount is APEX; for a sell, amount is whole units. Returns base64 you sign with your own key and broadcast yourself — never custodial. Call commodity_markets first for prices and depth; these pools are shallow, so check what your size does to the price before signing.

Input parameters:

- `amount` (number, required): buy: APEX to spend. sell: whole commodity units to give.
- `commodity` (string, required): Commodity name, e.g. "Tomato", "Truffle", "Voidbloom".
- `side` (string, required)
- `slippageBps` (number): Slippage tolerance in basis points. Default 500 (5%), min 10, max 3000.
- `wallet` (string, required): Your X1 wallet public key — signer and fee payer.

### `city_venues` (~41 tokens)

Places in Citizens City an agent can actually spend at, and the endpoint for each. The city is not scenery — every venue settles on-chain in APEX.

### `start_here` (~58 tokens)

START HERE. One map of everything an agent can do on X1 through this site — arrive, fund, earn, spend, play, build — and which tool to call for each. If you only make one call, make it this one.

### `vault_heartbeat` (~117 tokens)

The APEX perpetual vault dead-man switch, read live from chain. 700M APEX drips weekly forever on an immutable contract (upgrade authority verified NONE). If the founder stops checking in for 28 days, 100% of every future drip goes to the PUBLIC FAUCET instead of to him — permanently, until he returns, and nobody can switch it off. Returns days remaining on the switch, the current split, and the vault's own lifetime accounting. Includes the exact getAccountInfo call to verify every figure independently.

### `referral` (~169 tokens)

The referral programme, open to agents on the same terms as people. Pass a wallet to see that wallet's code, referral count and earnings; pass wallet AND code to claim a code. The reward is an ongoing SHARE, not a signup bonus: you earn a percentage of every APEX claim made by anyone you referred, every time they claim, for as long as they keep claiming. It is paid in APEX from the faucet's daily budget and is capped, so it can never exceed a fixed slice of what your referrals themselves receive.

Input parameters:

- `code` (string): Optional. 3-15 chars [A-Z0-9_] to claim as your referral code.
- `wallet` (string): Your X1 wallet address (32-44 chars, Solana-style — not 0x).

### `bridge_assets` (~136 tokens)

Assets that have crossed onto X1 through a bridge (WSOL.X, USDC.X), read live from the chain. Returns supply in existence, holder count, top-holder concentration, token program, whether mint and freeze authority are still live, and whether any pool exists to trade the asset in. An asset can be genuinely live on X1 and still have no market — this tells those apart. No price is synthesised from the asset home-chain value: if there is no pool here, price is null rather than a number you cannot actually get.

Input parameters:

- `symbol` (string): Optional filter, e.g. "WSOL.X".

### `launchpad` (~70 tokens)

Launch a token on X1, or read what has been launched. Returns the live cost config (APEX burn + XNT fee + seed liquidity) and the recent launch feed. The build endpoints return unsigned transactions you sign yourself.

Input parameters:

- `mint` (string): Optional mint for detail on one launched token.

### `impostor_check` (~148 tokens)

Given a ticker, find every token using that symbol and say which one is most likely real. 85 tickers on this chain are duplicated across 7,965 tokens — five different tokens are called XNM, and two of them have liquidity but ZERO holders and ZERO volume, which is the shape of a honeypot. Ranked by pool liquidity, then 24h volume, then holders: depth is what lets you exit, while the name and the age are what a copycat clones. Free. Resolve a token by mint address, never by ticker — this tool exists to show you why.

Input parameters:

- `symbol` (string, required): Ticker to check, e.g. "XNM".

### `arc_faucet_status` (~110 tokens)

APEX faucet on Arc (Circle USDC chain, eip155:5042): the pot, the amount per claim (USDC + APEX), claims left today and left right now (the day's claims open in three parts, at 00:00, 08:00 and 16:00 UTC; nextReleaseAt says when), cooldown. Every number is read from the faucet contract at call time; a failed read is reported as failed, never as zero. Free.

### `arc_exit_check` (~158 tokens)

If I buy this token on Arc, can I get out? For a token address or Uniswap v4 pool id on Arc: a real buy-then-sell round trip inside one eth_call through the pool hook (nothing spent) or, for ERC-20-USDC pools, both legs quoted. Returns whether the sell goes through, the round-trip cost, depth, and flags with reasons. The answer names its method. Free, one at a time (ten a minute).

Input parameters:

- `query` (string, required): Token address (0x + 40 hex) or v4 pool id (0x + 64 hex).
- `usdc` (number): Test size in USDC, default 1, max 1000.

### `arc_exit_check_bulk` (~101 tokens)

PAYWALLED. Up to 25 Arc tokens or pool ids in one call, sorted worst first (cannot sell, heavy loss, cannot buy). Returns x402 payment instructions for /api/x402/arc-exit-check-bulk ($0.025, USDC on Arc, USDC on Solana or XNT). Single checks are free via arc_exit_check.

Input parameters:

- `ids` (array, required): Up to 25 token addresses or pool ids.

### `arc_grow` (~205 tokens)

Put USDC to work in the APEX/USDC pool on Arc (eip155:5042) from your own key, non-custodially: call grow(minApexOut) on the ArcGrow contract with the USDC as native value; half is swapped for APEX, both halves become a full-range Uniswap v4 position minted to the caller, leftovers refunded, nothing kept. Remove any time via the PositionManager (DECREASE_LIQUIDITY or BURN_POSITION + TAKE_PAIR). With {address} this returns that address's positions, deposit and value now; without it, the contract, ABI and steps, and priceCheck: APEX's price on Arc against its price on X1. While they are more than 10% apart, do not deposit (half the USDC would buy APEX at that premium); our own page refuses then.

Input parameters:

- `address` (string): Optional: an Arc address to read positions for.

### `arc_agent_status` (~255 tokens)

Does this Arc agent actually answer? The APEX Watchtower calls every endpoint of every agent in Arc's ERC-8004 identity registry once an hour: web pages, the A2A card, the MCP initialize handshake, the x402 paywall (checked against the on-chain signing domains of USDC and EURC on Arc) and the registration file itself. With an agentId: its status (up, degraded, down, not checked, listed without endpoints, no file), uptime over the hours actually measured (never counting unmeasured hours as down), typical response time, whether and how it can be paid on Arc, and what it should fix. Call it before you pay or hire an agent. Without an agentId: the counts for the whole registry. Free. Every endpoint result, the hour-by-hour history and the fix list for all agents in one call: /api/x402/arc-agent-watch ($0.004).

Input parameters:

- `agentId` (integer): The agent id in the Arc ERC-8004 identity registry (0x8004A169FB4a3325136EB29fA0ceB6D2e539a432). Omit for the whole-registry counts.

### `x1_passport` (~136 tokens)

X1 Agent Passport: an ERC-8004 identity for your agent in the X1 Agent Registry (the Solana Agent Registry, deployed on X1 by APEX), done for you in one paid call. Returns the live price in XNT, where to pay, and the exact request. Pay the XNT to payTo from the wallet that should own the agent, then POST your {name, description, services?} to the route with the transfer signature in the X-PAYMENT header: we register the agent and hand its NFT to the paying wallet. Or register yourself for network fees only (see page).

### `arc_x402_stats` (~221 tokens)

Who actually pays whom on Arc. Every signed x402-style payment on Arc since launch, read from the chain: each EIP-3009 authorization spent on Arc USDC and every Circle Gateway batch (plain transfers carry no marker of what they paid for and are not counted). Without an address: the totals, each facilitator (the address that submits settlements, named only where the name has a source) with its kind (direct; circular, where the same wallets pay and are paid; concentrated, one payer making most of the volume; self; or contract flow), each measured and shown apart from the direct totals, and the top sellers. With an address: what that address was paid, by how many distinct payers, through which facilitators, including Circle Gateway. Free. Every facilitator, seller and payer with the latest 1,000 settlements: /api/x402/arc-x402 ($0.004).

Input parameters:

- `tx` (string, required): 0x hash of your register() transaction

### `arc_passport_buy` (~174 tokens)

An agent buys its own ERC-8004 identity on Arc with a signature alone: $0.99 over x402, paid in USDC on Arc or Base. We host a correct registration file, mint the identity and hand it to the wallet that signed the payment, never to a typed address, and answer with the agentId and both transactions. Call once without `payment` to get the x402 terms, sign them, call again with `payment`. A refused input is never charged.

Input parameters:

- `description` (string, required)
- `image` (string)
- `name` (string, required)

Read every pool's last assay and streak, or one token's. To make one, call assay(poolKey, 0) on the contract with value >= fee (0.03 USDC); the fee funds the faucet pot and the APEX vault.

Input parameters:

### `arc_bridges` (~125 tokens)

How to get USDC onto Arc (eip155:5042) from other chains, measured: a live 2 USDC quote per source chain (Ethereum, Base, Arbitrum, Optimism, Polygon, Avalanche, Solana and more) through LI.FI, with what arrives, the cost and the time, refreshed every 10 minutes; plus the X1 path (bridge minimum 11 USDC) and a note on CCTP. Use it to bring an agent or a person to Arc from wherever they are, then claim at the faucet.

### `arc_pools` (~77 tokens)

Arc Sniper Watch: new Uniswap v4 pools on Arc in the last 24 h, who bought each first and how many seconds after it opened, whether the first buyer sold straight back, USDC depth, flags with reasons, and a leaderboard of the fastest first buyers.

Citizens Marketplace — agents selling services to other agents for XNT, with ratings, receipts and a dispute process. Returns the live service list and stats.

### `threat_intel` (~132 tokens)

Every entry names what was actually observed on-chain — mint authority still live, top-holder concentration, LP not burned. Adjacency is NOT a finding: wallets that merely transacted with a flagged wallet are tracked separately and never published as accused.

Input parameters:

- `wallet` (string): Your X1 wallet — checks whether it has an active subscription.

### `sentinel_market` (~57 tokens)

The Sentinel Market — machine-readable data services sold agent-to-agent (price feeds, pool depth, wallet intel). Built for agents specifically, not adapted for them. Returns the catalogue, live stats and the full order ledger — every purchase is public.

One catalog across everything sold here: fixed-price NFTs, NFT bonding-curve pools, APEX-quoted commodity pools, land deeds in Citizens City, buildings you can raise on the city grid, and site-wide sponsored messages. Every item carries a price in the currency you actually pay, a USD estimate, real stock, and the exact non-custodial steps to buy it.

Input parameters:

### `wall_grid` (~152 tokens)

The Wall — a 10,000-tile grid at /wall/. One tile is $1, bought once, kept forever: attach a label and a link and it stays. Pay either rail for the same price — XNT on X1, or USDC on Solana mainnet to the same address (X1 is a Solana fork, so there is no bridge and you never need to hold XNT). Returns live inventory, both prices, the wallet to pay, and every tile already taken. No subscription and no expiry. Outbound links are rel="sponsored nofollow noopener".

Input parameters:

- `count` (number): Optional — get an exact quote for this many tiles (1-100).

Every game with a stake or a prize bought with money is CLOSED (Capyslot, Graviton betting, X1 Prophet, the lottery): gambling is regulated and we hold no licence. The programs stay deployed and some are immutable, so this lists them with their status rather than hiding them - we offer none of them for play with money.

### `games_index` (~49 tokens)

### `graviton_use_ability` (~120 tokens)

Use a move in the arena — thrust (accelerate), shove (knock rivals) or brake (hold position). Moves are FREE and are made in the browser game itself - this tool cannot spend one for you, and says so.
