### `get_xch_price` (~123 tokens)

Current XCH spot price via CoinGecko. Accepts any currency CoinGecko supports (e.g. 'usd', 'eur', 'gbp', 'jpy', 'btc', 'eth'); defaults to ['usd']. Free-tier API is rate-limited; results are cached for 60 seconds.

Input parameters:

- `currencies` (array): Fiat or crypto currency codes accepted by CoinGecko (e.g. 'usd', 'eur', 'gbp', 'jpy', 'btc', 'eth'). Case-insensitive. Defaults to ['usd'].

### `convert_xch_to_fiat` (~177 tokens)

Convert a mojo amount to its current fiat (or other CoinGecko-supported currency) value. 1 XCH = 1,000,000,000,000 mojo — convert XCH to mojo before calling. Prices come from CoinGecko (cached 60s). Returned values use JS floating-point; precise to far more decimals than any realistic balance.

Input parameters:

- `currencies` (array): Fiat or crypto currency codes accepted by CoinGecko (e.g. 'usd', 'eur', 'gbp', 'jpy', 'btc', 'eth'). Case-insensitive. Defaults to ['usd'].
- `mojo` (string, required): Non-negative integer mojo amount as a decimal string. 1 XCH = 1,000,000,000,000 mojo. Convert XCH amounts to mojo before passing.

### `get_prefarm_status` (~66 tokens)

Aggregate status of the Chia strategic reserve (21M XCH across four custody wallets: US/CH × cold/warm). Per-wallet balances are read live from coinset.org; the only hardcoded amount is the 21M XCH genesis total. Mainnet only.

### `get_prefarm_spends` (~126 tokens)

List outflows from the Chia strategic reserve. For each spent coin: the source wallet, the destination addresses (labelled when they map to a known partner / market maker / exchange), and amounts. Internal rotations between custody wallets are flagged and excluded from total outflow. Mainnet only.

Input parameters:

- `limit` (integer): Maximum spends to return, sorted newest first. Default 50.
- `since_height` (integer): Only include spends at or after this block height.
- `wallet_id` (string): Restrict to one wallet. Omit to query all four.

### `list_prefarm_addresses` (~64 tokens)

Return the hardcoded registry of Chia strategic-reserve custody wallets and labelled destination addresses (partners, market makers, exchanges). Identities only — balances are not returned here; call `get_prefarm_status` for live amounts. Pure local data, no network call.

### `decode_offer` (~92 tokens)

Decode a Chia 'offer1...' string locally (no external API). Returns a structured trade summary: what assets are offered, what is requested, and per-asset amounts and IDs. Classifies XCH, CATs (with asset_id), NFTs (with launcher_id), and DIDs.

Input parameters:

- `offer` (string, required): A Chia offer string starting with 'offer1'. Bech32m-encoded.

### `decode_spend_bundle` (~82 tokens)

Decode a raw hex-encoded Chia spend bundle (e.g. a mempool item, or any bundle that is not wrapped in an offer string) into the same structured trade-summary shape as decode_offer. Useful for inspecting pending mempool transactions.

Input parameters:

- `spend_bundle` (string, required): Hex-encoded spend bundle bytes (with or without 0x prefix).

### `decompile_puzzle` (~254 tokens)

Classify a Chia CLVM puzzle reveal. Returns its kind (xch, cat, nft, did, singleton, unknown), asset_id for CATs, launcher_id for NFTs/DIDs, and the inner p2 puzzle hash. Either pass `puzzle_reveal` as hex directly, OR pass `coin_id` + `height` to auto-fetch from the full node. Set `include_conditions: true` to also parse the conditions a spend emits (requires `solution` hex, or a spent coin reachable via coin_id + height).

Input parameters:

- `coin_id` (string): 32-byte coin id. Use with `height` to auto-fetch the puzzle reveal.
- `height` (integer): The spent_block_index of the coin (where it was spent).
- `include_conditions` (boolean): If true, run the puzzle with the solution and parse the emitted conditions.
- `network` (string): Chia network: 'mainnet' (default) or 'testnet11'
- `puzzle_reveal` (string): Hex-encoded puzzle reveal. Omit to auto-fetch via coin_id + height.
- `solution` (string): Hex-encoded solution. Only used when include_conditions is true.

### `get_mempool` (~146 tokens)

List transaction ids currently in the full node mempool. By default returns the first `limit` ids (default 100, max 1000) plus a `truncated` flag. Pass `include_items: true` to also return the full mempool items (warning: can be large on a busy mempool).

Input parameters:

- `include_items` (boolean): If true, also fetch full mempool items via get_all_mempool_items.
- `limit` (integer): Maximum number of tx_ids (and items) to return. 1..1000.
- `network` (string): Chia network: 'mainnet' (default) or 'testnet11'

### `is_in_mempool` (~115 tokens)

Check whether a specific transaction id (the spend bundle hash) is currently sitting in the full node mempool. Returns `in_mempool: true` with the mempool item, or `in_mempool: false` if the node has no record of it.

Input parameters:

- `network` (string): Chia network: 'mainnet' (default) or 'testnet11'
- `tx_id` (string, required): 32-byte transaction id (spend bundle hash). Hex, optional 0x prefix.

### `estimate_fee` (~178 tokens)

Estimate the recommended mojo fee for inclusion in the next block within each target time (in seconds). Default target_times = [60, 300, 900] (1, 5, 15 minutes). Optionally bias the estimate by passing `spend_type` and `spend_count`, or supply an explicit CLVM `cost`.

Input parameters:

- `cost` (integer): Optional CLVM cost of the spend bundle you plan to send.
- `network` (string): Chia network: 'mainnet' (default) or 'testnet11'
- `spend_count` (integer): Optional hint: number of spends in the bundle.
- `spend_type` (string): Optional hint about the kind of spend (biases the estimate).
- `target_times` (array): Target inclusion times in seconds. Non-empty array, max 20 entries.

### `list_chips` (~213 tokens)

List all Chia Improvement Proposals (CHIPs) from the canonical index in the Chia-Network/chips repo README, across every status (Living, Draft, Review, Final, Stagnant, Withdrawn, Obsolete, Grandfathered, Under Consideration). Draft and Review entries point to open PRs; Final entries point to merged files on main. Status comes from the README (authoritative); category, authors, and abstract are enriched from front matter when a CHIP file is available. Use this to find the most recent CHIPs — they are typically in Draft. Optional filters: status, category.

Input parameters:

- `category` (string): Restrict to a category, e.g. 'Standards Track', 'Process', 'Informational'. Case-insensitive.
- `status` (string): Restrict to a status, e.g. 'Final', 'Review', 'Draft', 'Last Call', 'Living', 'Stagnant', 'Withdrawn', 'Obsolete'. Case-insensitive.

### `get_chip` (~109 tokens)

Get a single CHIP by number. Looks first on main (merged) and also surfaces any open PRs proposing changes to the same number. Returns parsed front matter, abstract, source URL, and (with include_body=true) the full markdown body.

Input parameters:

- `include_body` (boolean): If true, include the full markdown body of the CHIP. Defaults to false.
- `number` (required): CHIP number, e.g. 42 or "0042". Accepts the integer or a zero-padded string.

### `list_chip_drafts` (~97 tokens)

List the live state of every open pull request against Chia-Network/chips that adds or modifies a CHIP file. Use this for PR review context (author, requested reviewers, draft flag, updated_at) and the modifies_existing flag for amendments. PRs that do not touch a CHIPs/chip-*.md file are filtered out. For the canonical CHIP index across all statuses (including Draft proposals), use list_chips.

### `search_chips` (~179 tokens)

Case-insensitive keyword search across merged CHIPs and open PR drafts. Matches against title, description, abstract, authors, and CHIP number. Optional filters: status, source (merged | draft | both, default both), limit (default 20).

Input parameters:

- `limit` (integer): Maximum results. Default 20, max 100.
- `query` (string, required): Case-insensitive keyword matched against title, description, abstract, and authors.
- `source` (string): Where to search: 'merged' (CHIPs on main), 'draft' (open PRs), or 'both' (default).
- `status` (string): Restrict to a status, e.g. 'Final', 'Review', 'Draft', 'Last Call', 'Living', 'Stagnant', 'Withdrawn', 'Obsolete'. Case-insensitive.

### `list_forks` (~142 tokens)

List every Chia consensus fork (hard and soft) with current status, drawn from the canonical docs page at https://docs.chia.net/chia-blockchain/consensus/forks/ (sourced from the Chia-Network/chia-docs GitHub repo). Each entry has type ("hard" | "soft"), name, activation_block, activation_date, build, status (e.g. Activated, Planned), and a purpose_url linking to the relevant CHIP, post-mortem, or blog post when available. Includes the source's last_updated date so callers can judge freshness. No arguments, no network selector (consensus forks are protocol-level).
