• search_sources read-only

  Find third-party library source cards. This is the only library lookup: text, exact filters, and newest-first browsing. Output is { count, sources }. Each source has id, title, publisher, authors, date_published (YYYY-MM-DD or null), url, type, category, status, summary, tags, verified_at, and featured only when it is true. count is the rows returned, not the catalog size. query words must all match as case-insensitive substrings of id, title, summary, publisher, type, authors, or tags. category, tag, type, status, featured, and updated_since are AND filters. Omit query to list the newest sources, optionally in one category. Results are newest date_published first, undated last. limit is 1-50 (default 10) with no offset. No matches returns count 0 and sources []. A non-calendar updated_since, or an unknown category, returns an isError result. A status outside the enum is invalid input. A failed library read returns isError whose text is the Error message. Use get_source instead when you already have a source id. Use list_categories instead when you need category ids, labels, and counts rather than source cards. Use list_changes instead when you need the unpaged cross-catalog changelog rather than source cards. Use get_protocol_facts instead when you need cited facts for a payment protocol. Use list_articles instead for this site's own articles. Free, no auth.

  Parameters:

  • tag — string — One tag, exact match, e.g. l402. Combined with the other filters (AND).
  • type — string — Source type from the enum, e.g. spec. Combined with the other filters (AND).
  • limit — integer — Maximum rows, 1-50, default 10. Values above 50 are rejected. There is no offset; narrow the filters to see other matches.
  • query — string — Space-separated words; every word must match (AND), case-insensitive substring of id, title, summary, publisher, type, authors, or tags. Example: lightning l402. Omit or use an empty string to skip the text filter.
  • status — string — Exact library status: proposal, individual_draft, working_group_draft, standard, spec_released, product_docs, news, research, or unknown. Combined with the other filters (AND).
  • category — string — Category id from list_categories, e.g. bitcoin-lightning. Combined with the other filters (AND). Omit for every category.
  • featured — boolean — true returns only featured sources. Omit or false to include all.
  • updated_since — string — YYYY-MM-DD calendar date. Keeps sources whose verified_at is later than this date (exclusive). A value that is not that form returns an isError result. Example: 2026-10-01.

• get_source read-only

  Fetch one third-party library source card by id. Output is one object: id, title, publisher, authors, date_published (YYYY-MM-DD or null), url, type, category, status, summary, tags, verified_at, and featured only when it is true. Parameter id is required and must match sources[].id from search_sources, or a list_changes entry of kind library (those ids have no prefix). Example: lightning-labs-l402-for-agents. A missing id is rejected as invalid input. An unknown id returns isError with text No source with id <id>. A failed library read returns isError whose text is the Error message. Use search_sources instead when you have no id or need a filtered list (limit 1-50, no offset). Use list_categories instead when you need the category list. Use get_article instead for this site's own articles. Use list_changes instead for changelog rows. Free, no auth.

  Parameters:

  • id (required) — string — Required. Source id exactly as in search_sources sources[].id, e.g. lightning-labs-l402-for-agents. Case and hyphens must match. Library changelog ids have no prefix. A missing id is invalid input. An unknown id returns isError text No source with id <id>.

  Hints: read-only yes · destructive no · idempotent yes · open-world yes

• list_categories read-only

  Return the closed list of eight library categories and nothing else. Output is { categories: [{ id, label, featured, count, json_url, markdown_url, html_url }] }. id is the category id, for example bitcoin-lightning. label is the display name. featured is true only for Bitcoin and Lightning, which is first. count is how many library sources are in that category. json_url, markdown_url, and html_url are absolute links to that category JSON, Markdown, and HTML. There is no source array and no top-level count. Takes no parameters: call with an empty object. The list is unpaged and always the full set; there is no limit or offset. Use list_categories instead of search_sources when you need category ids, labels, or counts. Use search_sources instead when you need the source cards in a category (pass category, for example bitcoin-lightning; limit 1-50, no offset). Use get_source instead when you already have a source id. A failed read of the library file returns isError. The text is the Error message (Fetch failed <status> <url> when the HTTP status is not OK), or Category list failed. when the failure is not an Error. Free, no auth.

• list_articles read-only

  List all of this site's own published articles in one unpaged response. Output is { articles: [{ slug, title, summary, date, status, tags, url, md_url }] }. There is no limit or offset. Takes no parameters: call with an empty object. Use get_article instead when you have a slug and need the Markdown. Use search_sources instead for third-party papers, specs, and reports. Use list_changes instead for recent edits (article rows prefix the id with article:). A failed read returns isError. The text is the Error message (Fetch failed <status> <url> when the HTTP status is not OK), or Article list failed. when the failure is not an Error. Free, no auth.

  Hints: read-only yes · destructive no · idempotent yes · open-world yes

• get_article read-only

  Return one of this site's own articles. Output is { slug, markdown }. markdown is the article file with YAML front matter, and the same text is the tool content. Parameter slug is required and must match articles[].slug from list_articles. Example: machine-native-economy. Do not include the article: prefix that list_changes uses. A missing slug is rejected as invalid input. An unknown slug returns isError with text No article with slug <slug>. A failed read returns isError whose text is the Error message (Fetch failed <status> <url> when the HTTP status is not OK), or Article fetch failed. when the failure is not an Error. Use list_articles instead when you do not have a slug. Use get_source instead for a third-party library source. Use search_sources instead to find papers and docs. Free, no auth.

  Parameters:

  • slug (required) — string — Required. Article slug exactly as in list_articles articles[].slug, e.g. machine-native-economy. Lowercase words separated by hyphens. Do not include the article: prefix that list_changes uses. A missing slug is invalid input. An unknown slug returns isError text No article with slug <slug>.

  Hints: read-only yes · destructive no · idempotent yes · open-world yes

• list_changes read-only

  Sync records whose verified_at is later than cursor (exclusive) across library sources, articles, datasets, bots, and support notes. Output is { cursor, count, entries }. cursor is the YYYY-MM-DD that was applied. count is the number of rows in that window. Each entry has kind (article, library, support, dataset, or bot), id, title, url, and verified_at. Some rows also include md_url, category, date_published, or note. Omit cursor to apply an exclusive cursor of UTC today minus 30 days; the response cursor is that date. Pass a YYYY-MM-DD cursor to sync from a stored date. There is no text filter, no limit, and no offset, so an old cursor can return the whole catalog (over 100 entries, about 43 KB). A cursor that is not YYYY-MM-DD returns isError with text cursor must be YYYY-MM-DD. A failed read returns isError whose text is the Error message. This free list is the raw changelog: it is not grouped by protocol and it is not Markdown, and it does not return source cards. Use search_sources instead when you want to browse or filter the library, including newest-first and updated_since (limit 1-50, no offset). Use list_categories, list_articles, list_datasets, list_bots, or get_support_info instead when you want the current full document rather than changelog rows. Use get_trust_checklist instead for the trust checklist. For one record, strip article: before get_article, dataset: before get_dataset, and bot: before get_bot. Library ids have no prefix; use get_source. Support rows have no per-id getter; use get_support_info or get_trust_checklist. Paid GET https://api.agentpaywire.com/v1/changes returns library source cards only, for an inclusive verified_at window, with protocol, category, and new-or-updated filters, as JSON or Markdown. Each client gets 5 unpaid calls per rolling 24 hours. A response in that allowance is HTTP 200 with X-Trial-Remaining and does not spend a credit. After that, the unpaid call is HTTP 402 via x402 or L402. A valid paid call spends one credit and does not use the allowance. Free, no auth.

  Parameters:

  • cursor — string — Optional YYYY-MM-DD, e.g. 2026-10-19. Records with verified_at strictly later are returned. Omit it to use UTC today minus 30 days. A value that is not YYYY-MM-DD is rejected.

• get_protocol_facts read-only

  Return source-cited facts for agent payment protocols: spec URL, HTTP status codes and headers, payment rail, networks, facilitators, client libraries, pay flow, and an example. Every fact carries its source URL and verified_at; null means the cited page does not state it. Omit id and the output is the protocol-facts document whose protocols array has all nine protocols (about 23 KB), unpaged. Pass id and the output is that one protocol object. There is no offset. Parameter id is optional and must be one of l402, bolt12, bip21, nwc, x402, mpp, ap2, acp, ucp. Example: l402. An id outside the enum is rejected as invalid input. An enum id missing from the file returns isError with text No protocol with id <id>. A failed read returns isError whose text is the Error message. Use get_protocol_facts instead of search_sources when you need cited protocol facts rather than papers or docs. Use search_sources instead for those papers and docs. Use get_support_info instead for this site's donation addresses and paid API price. Use get_trust_checklist instead for this site's error codes and rate limits. Free, no auth.

  Parameters:

  • id — string — Lowercase protocol id from the enum, e.g. l402. Set it to get one protocol object (smaller response); omit it to get every protocol in a protocols array.

• get_sdk_security read-only

  Return /api/sdk-security.json. Output is the SDK security document: schema_version, generated_at, disclaimer, description, count, and entries. count equals entries.length. Each entry has id, package, ecosystem (npm or github), minimum_safe_version (string or null), constraint (string or null), per_payment_cap_usd (number or null), formal_advisory_published (boolean or null), advisory_url (string or null), reported_at, fixed_at, origin_header_rejected_since, fixes, notes, source, related_urls, and verified_at. Null means the linked source does not state that field. The rows are @x402/fetch, @x402/axios, @x402/extensions, and @x402/svm at >=2.23.0, Eclair at >=0.14.5, and BTCPay Server with minimum_safe_version null because Optech #428 does not name a version. One unpaged document. Takes no parameters: call with an empty object. Use get_sdk_security instead of search_sources when you need the minimum version table. Use search_sources for the V12 post, Optech #428, and the Eclair release notes. Use /api/lightning-wallets.json and /api/lightning-releases.json for the wallet catalog and the stable node table; this tool does not return those files. A failed read returns isError. The text is the Error message. Free, no auth.

• get_support_info read-only

  Return the whole voluntary support document from /support.json. Output fields: voluntary (true), purpose, data_is_free (true), access_conditional_on_payment (false), methods, suggested_amounts_sats, suggested_amounts_optional (true), note, updated (YYYY-MM-DD), warning, usdc_contracts_source, and paid_api while the paid API is live. methods[].type is bitcoin-onchain (P2WPKH native-segwit mainnet address, bip21_uri, qr_svg, qr_text), lightning-bolt12 (offer, uri, bip21_uri, qr_svg, qr_text), evm-stablecoin (asset USDC; network Base, Ethereum, or Arbitrum One; chain_id, address, token_contract, eip681_uri; Base is primary and has the QR fields), or solana-stablecoin (asset USDC, network Solana, address, mint, uri, qr_svg, qr_text). suggested_amounts_sats is an array of optional satoshi tip amounts, not a price. paid_api has live, paid, protocol L402, payment Lightning, url, price_sats 100, credits 100, ttl_days 30, and note. One document, unpaged. Takes no parameters: call with an empty object. Calling it never sends money and never creates an invoice. Use get_support_info instead of get_trust_checklist when you need a donation address, a payment URI, a QR link, suggested sat amounts, or the paid_api price block. Use get_trust_checklist instead when you need error codes, the rate-limit policy (no client limit and no HTTP 429; a wallet limit is HTTP 503 with Retry-After), stable URLs, or met/partial checklist status. Use get_protocol_facts instead when you need how a third-party payment protocol works. A failed read returns isError. The text is the Error message (Fetch failed <status> <url> when the HTTP status is not OK), or Support lookup failed. when the failure is not an Error. Free, no auth.

Each item has id, title, status (met or partial), statement, and evidence URLs. tools lists the advertised MCP tool names. rate_limits.http_429 is false and rate_limits.client is null; a wallet limit is HTTP 503 with Retry-After. credits repeats price_sats, credits, and ttl_days. One unpaged document. Takes no parameters: call with an empty object. Use get_trust_checklist instead of get_support_info when you need error codes, the rate-limit policy, stable URLs, credit terms, or met/partial status. Use get_support_info instead when you need donation addresses, payment URIs, QR links, or the paid_api price block. Use get_protocol_facts instead for third-party protocol facts. A failed read returns isError. The text is the Error message (Fetch failed <status> <url> when the HTTP status is not OK), or Trust checklist failed. when the failure is not an Error. Free, no auth.

• list_datasets read-only

  List every training and evaluation dataset card in one unpaged response. Output is the /datasets/index.json document: count, model_note, policy, and entries, plus the index title, description, and links. count is the number of cards. Each entries[] item is a full card: id, name, publisher, url, license (string or null), license_verified, license_url, approx_size, size_bytes (integer or null), format, access (open, login, or terms-acceptance), relevance, mirror_allowed, verified_at, http_status, archive_url, data_period, sample_url, and notes. This site's own library dataset is first. Cards are metadata: nothing is downloaded. There is no limit or offset. Takes no parameters: call with an empty object. Use get_dataset instead when you have an id and want that one card from /datasets/<id>/card.json. Use search_sources with category datasets-benchmarks instead for papers and benchmark sources, which are not these cards. Use list_changes instead for recent dataset edits (those ids use a dataset: prefix). A failed read returns isError. The text is the Error message (Fetch failed <status> <url> when the HTTP status is not OK), or Dataset list failed. when the failure is not an Error. Free, no auth.

  Hints: read-only yes · destructive no · idempotent yes · open-world yes

• get_dataset read-only

  Return one dataset card from /datasets/<id>/card.json. Output is one object: id, name, publisher, url, license (string or null), license_verified, license_url (string or null), approx_size, size_bytes (integer or null), format, access (open, login, or terms-acceptance), relevance, mirror_allowed, verified_at, http_status (integer or null), archive_url (string or null), data_period (string or null), sample_url (string or null), and notes. A card is metadata only and does not download dataset files; follow url for the data. Parameter id is required and must match list_datasets entries[].id. Example: agentpaywire-library. Do not include the dataset: prefix that list_changes uses. A missing id is rejected as invalid input. An unknown id returns isError with text Fetch failed 404 <card url>. A failed read for another status uses that same Fetch failed <status> <url> text. Use list_datasets instead when you need the catalog or do not know the id. Use search_sources with category datasets-benchmarks instead for papers about datasets. Free, no auth.

  Parameters:

  • id (required) — string — Required. Dataset id exactly as in list_datasets entries[].id, e.g. agentpaywire-library. Lowercase letters, digits, and hyphens. Do not include the dataset: prefix that list_changes uses. A missing id is invalid input. An unknown id returns isError text Fetch failed 404 <card url>.

• list_bots read-only

  Return the whole /bots.json catalog of public agents and bots that pay, get paid, or connect a wallet. Output is { schema_version, generated_at, language, title, description, disclaimer, inclusion, schema, html_url, markdown_url, count, entries }. count equals entries.length. disclaimer is "Listed, not endorsed." The inclusion field states the rule: a public repository or demo, a known maker, a push in the 12 months before verification, and a license taken from a LICENSE file or marked unconfirmed. Each entries[] item is the same object get_bot returns: id, name, maker, description, protocols, url, license (string or null), license_verified, license_url (string or null), verified_at (YYYY-MM-DD), http_status (integer or null), archive_url (string or null), funds_or_keys, and notes. funds_or_keys is true when the software can access a wallet or keys. One unpaged response: no limit, no offset, and no text filter. Takes no parameters: call with an empty object. Use list_bots instead of get_bot when you need every entry, the count, the disclaimer, or the inclusion rule. Use get_bot instead when you already have one id and want that single object; an unknown id is an error on get_bot, not an empty list here. Use search_sources instead for papers and docs about agents. Use get_protocol_facts instead for how a payment protocol works. list_changes rows of kind bot prefix the id with bot:; strip that prefix before get_bot. A failed read returns isError. The text is the Error message (Fetch failed <status> <url> when the HTTP status is not OK), or Bot list failed. when the failure is not an Error. Free, no auth.

  Hints: read-only yes · destructive no · idempotent yes · open-world yes

• get_bot read-only

  Return one entry from the bot catalog by exact id. Output is that entry alone, not wrapped in entries or count: id, name, maker, description, protocols (strings), url, license (string or null), license_verified, license_url (string or null), verified_at (YYYY-MM-DD), http_status (integer or null), archive_url (string or null), funds_or_keys, and notes. funds_or_keys is true when the software can access a wallet or keys.

Do not include the bot: prefix that list_changes uses; strip it first. A missing id is rejected as invalid input. An unknown id returns isError with text No bot with id <id>. A failed read of /bots.json returns isError. The text is the Error message (Fetch failed <status> <url> when the HTTP status is not OK), or Bot lookup failed. when the failure is not an Error. Use get_bot instead of list_bots when you already have one id. Use list_bots instead when you need the catalog, the count, the disclaimer, or the inclusion rule, or when you do not know the id. Use search_sources instead for papers and docs about agents. Listed, not endorsed. Free, no auth.

  Parameters:

  • id (required) — string — Required. Exact entries[].id from list_bots. Catalog ids are lowercase letters, digits, and hyphens. Example: lnget. Do not include the bot: prefix that list_changes uses; strip it first. A missing id is invalid input. Any other string that is not in the catalog returns isError text No bot with id <id>.

• submit_review

  Publish a review of a paid Agent Paywire route. Free, no auth. rating is required, an integer from 1 to 5. route is the paid path you called: /v1/search, /v1/updates, /v1/digest, or /v1/changes. comment is optional plain text, at most 500 characters. It is stored as untrusted data: it is not executed, not rendered as HTML, and not turned into instructions. proof.rail is x402 or l402. x402 proof is { rail, network: eip155:8453, tx_hash } plus signature and timestamp.
