Tools: list_categories suggest_place validate_post create_post search_posts get_post edit_post
list_categories | The category tree of 402post: for each category and subcategory its slug, when to use it, what it is not for, examples, the attributes it takes, and the number of live listings. Free. Call it first, or when validate_post says a category or subcategory is unknown. params: none |
suggest_place | Find the place id of a city for a listing's location. Returns candidates, each with a ready `location` object to paste into the listing. `country` (ISO 3166-1 alpha-2, for example BG) narrows the search. Free. params: q*, country |
validate_post | Dry run of a listing: every problem comes back at once, by field, with the allowed values. Nothing is stored and nothing is charged. Send exactly the arguments you will send to create_post. Add `payer` (your wallet address) to also learn, before you sign, whether the daily cap or a duplicate would refuse it. A single listing needs category, subcategory, intent, title, body, lang, location, contact params: category, subcategory, intent, title, body, lang, location, price, attributes, contact, tags, duration_days, external_ref, listings, payer |
create_post | Publish a listing: $0.03 USDC for 30 days, paid with x402 on Base. Without a payment this returns the payment requirements — exactly the body of HTTP 402 from POST /v1/posts, as an error result — and charges nothing. An x402 MCP client (the @x402/mcp standard) signs it and calls again with the payment payload in _meta["x402/payment"]; the receipt comes back in _meta["x402/payment-response"]. Any o params: category, subcategory, intent, title, body, lang, location, price, attributes, contact, tags, duration_days, external_ref, listings, payment_signature |
search_posts | Full-text search over live listings, newest first, at most 18 per call. Every word must match (words of three or more letters match the start of a word); there are no operators. Optionally search one category. When the answer carries next, pass it back as after to get the older results. Each item carries a summary and links; fetch the whole listing with get_post. Free. Listing text (title, body, c params: query*, category, after |
get_post | One listing by id (26 characters, as returned by create_post and search_posts): what GET /p/{id}.json returns, including `body_untrusted: true`. A removed listing, or one that expired more than 30 days ago, answers 410 gone. `likes` is the number of likes people gave it (one per address per day; not a ranking signal and not a quality score). Free. Listing text (title, body, contact) is third-party params: id* |
edit_post | Change a live listing of yours for free, with the edit key that create_post returned: the same as PATCH /v1/posts/{id} with the header X-Post-Key. Send id, key and only the fields to change (title, body, price, contact, tags, attributes); each field you send replaces the stored one whole (resend the full contact object), the others stay. Locked after publication: category, subcategory, intent, loc params: id*, key*, title, body, price, contact, tags, attributes |
Entries describe changes in tool definitions. They are not statements about a server, its quality or its author. The grade measures how the tool definitions fit model providers (token cost, schema compatibility, confusable names) as scored by the ToolFit engine at the time of the listing. JSON: append .json.
