## Trust breakdown

How this component scores in each security and reliability category. Every signal is checked automatically against the live server, and we only credit what we can confirm. Scores are 0–100 per category. Scoring method: https://verifymcp.io/docs/scoring (what has changed: https://verifymcp.io/docs/scoring/changelog)

Scored 2026-08-18.

- **Endpoint Security**: 69/100
  - The endpoint's TLS certificate is valid, in date, and uses a strong key.
  - No authorisation is required to call this server. Every tool declares its destructiveHint and none is destructive, so open access doesn't expose one.
  - HTTPS enforcement could not be verified: the plaintext port answered with HTTP 405, which proves neither a plaintext path nor enforcement.
  - The HSTS (Strict-Transport-Security) header is present.
  - DNSSEC check failed: this domain isn't protected by DNSSEC.
- **Transport & Reachability**: 100/100
  - Verified streamable-http transport via a live MCP handshake.
- **Schema Quality & AI Usability**: 60/100
  - AI-judged instruction clarity (excellent).
  - Context-footprint check failed: tool/resource definitions use about 2954 tokens (~369/item across 8 items; 8 tools + 0 resources), over budget; trim descriptions and params.
  - Usage-examples check failed: none of the tools include examples.
- **Stability & Change Management**: 20/100
  - Stability observed for 6 of 30 days with no destabilising changes; credit accrues until the full window elapses.
- **Tool Coverage**: 100/100
  - 100% of tools have a non-trivial description (not blank, and not just the tool's name).
  - 100% of tool parameters carry a description.
  - Structured output schemas are declared (100% of tools); any adoption earns full credit.
- **Capabilities**: 100/100
  - Implements a supported MCP spec version (2025-11-25); the latest is 2026-07-28.

Pass `chain` as one of: solana, solana-devnet, ethereum, sepolia, polygon, amoy, bsc, bsc-testnet, base, base-sepolia, tempo, tempo-testnet, arbitrum-one, monad, skale-base-sepolia. Omit `chain` (or pass `all`) to query every resolvable chain in one call.

Input parameters:

- `chain` (string): Blockchain network, or "all" (default) for every supported chain. One of: solana, solana-devnet, ethereum, sepolia, polygon, amoy, bsc, bsc-testnet, base, base-sepolia, tempo, tempo-testnet, arbitrum…

### `market.crypto` (~746 tokens)

Crypto market data (pay-per-call)

Crypto market-data lookups (CoinGecko-sourced pricing and market data), paid per call in USDC/USDm directly from the caller's own wallet via the x402 protocol — no Abstraxn account needed. Pick one `action`:

\- search ($0.001): fuzzy-search coins by name/symbol. Requires `q`. Call this first to resolve a coin id before using price_feed or historical_data, both of which need an id (e.g. "bitcoin"), not a ticker.
\- price_feed ($0.001): current price (and optionally 24h change / market cap) for one or more coins. Requires `ids` (comma-separated coin ids). Optional `currencies` (comma-separated fiat codes, default "usd"), `include_24h` (default true), `include_mcap` (default false).
\- market_data ($0.002): coins ranked by market cap (or another order) — use for "top N coins" / market overview questions. Optional `currency` (default "usd"), `category`, `order` (default "market_cap_desc"), `limit` (1-250, default 100), `page` (default 1).
\- historical_data ($0.003): historical price/market cap/volume series for one coin. Requires `id`. Optional `currency` (default "usd"), `days` (lookback window or "max", default 30), `interval` (e.g. "daily").
\- trending ($0.001): currently trending coins by search interest. No extra parameters.
\- token_prices ($0.005): DEX-derived prices for up to 200 tokens in one call. Requires `tokens`, an array of `{chain, token_address}` objects.

Prices above are indicative — the exact charge for a given call is always whatever the live payment challenge specifies for that request. The first call (no `paymentPayload`) returns `paymentRequired`; retry with the same arguments plus `paymentPayload` to complete payment and get the real result.

Input parameters:

- `action` (string, required): Which market-data operation to perform.
- `category` (string): market_data: category filter, e.g. "decentralized-finance-defi".
- `currencies` (string): price_feed: comma-separated fiat currency codes, default "usd".
- `currency` (string): market_data / historical_data: currency code, default "usd".
- `days` (string): historical_data: lookback window in days, or "max". Default 30.

- `ids` (string): price_feed: comma-separated coin IDs, e.g. "bitcoin,ethereum".
- `include_24h` (boolean): price_feed: include 24h price change (default true).
- `include_mcap` (boolean): price_feed: include market cap (default false).
- `interval` (string): historical_data: data granularity, e.g. "daily".
- `limit` (integer): market_data: max results, default 100.
- `order` (string): market_data: sort order, default "market_cap_desc".
- `page` (integer): market_data: page number, default 1.
- `paymentPayload` (object): x402 payment payload from a previous `paymentRequired` challenge. Omit on the first call.
- `q` (string): search: coin name or symbol to search for, e.g. "btc".
- `tokens` (array): token_prices: array of {chain, token_address} pairs to price, max 200 entries.

Output parameters:

- `error` (object)
- `paymentRequired` (object)

### `web3.lookup` (~598 tokens)

Wallet / token / ENS / tx-simulation lookups (pay-per-call)

Multi-chain wallet, token, ENS, and transaction-simulation lookups, paid per call in USDC/USDm directly from the caller's own wallet via the x402 protocol — no Abstraxn account needed. Pick one `action`:

\- wallet_balances ($0.005): token balances for a wallet across 20+ chains. Requires `chain` and `address`.
\- wallet_transactions ($0.005): transaction history with asset transfers for a wallet. Requires `address`. Optional `chain`, `limit`.
\- wallet_pnl ($0.01): realized and unrealized profit/loss per token for a wallet. Requires `chain` and `address`.

Prices above are indicative — the exact charge for a given call is always whatever the live payment challenge specifies for that request. The first call (no `paymentPayload`) returns `paymentRequired`; retry with the same arguments plus `paymentPayload` to complete payment and get the real result.

Input parameters:

- `action` (string, required): Which web3 operation to perform.
- `address` (string): Address to look up — a wallet address for wallet_balances / wallet_transactions / wallet_pnl / ens_reverse, or a token contract address for token_metadata.
