How this service works

Where to list an MCP server, x402 API, AI agent or skill - places checked by us, in 5 sections (free and working, paid, backlink only, lists you by itself, broken). $0.01 per record, 5-50 records per call: POST {"n":5} costs $0.05. Each record: how to submit (URL, method, fields, sign-in, review time) and how to check you are listed (URL + control). Next records: same body with after=next_cursor. Only changes: since=<edition>. Whole edition: GET /v1/places/all, $0.99. Free index: GET /v1/places

Output

A JSON object with a list of directory records (up to 50 per call), each containing the directory name, domain, section classification (free/paid/backlink/auto/broken), submission details (URL, HTTP method, form fields, sign-in requirement, review time), and a verification object (URL and control listing to confirm inclusion). Also includes the current edition date, remaining record count, next pagination cursor, and payment receipt.

Example use cases

Launching a new MCP server

“I just published a new MCP server and want to get it listed everywhere I can — give me 20 directories where I can submit it, including free ones, and tell me how to submit to each and how to check that my listing went through.”

Monitoring directory catalog changes

“I already submitted my x402 API to directories last month — give me 15 records from the MCP and x402 catalog list that have changed since 2025-06-01 so I know if there are new places to submit or if any old ones broke.”

Backlink acquisition for AI tool

“I'm trying to build backlinks for my AI agent product — show me 10 directories from the AI skills catalog that accept submissions just for backlinks, with the submission URL and review details.”

When to prefer

Use this endpoint when you need a curated, up-to-date, paginated list of places to submit an MCP server, x402 API, or AI agent for discovery. It is the right choice when you want structured submission instructions (not just a URL) and want to track changes over time using edition-based diffing. Prefer it over a web search when you need machine-readable, agent-actionable submission metadata with verification controls.

Side effects

n out of range (must be 5–50) — returns validation error
invalid cursor format in 'after' field — returns cursor error or empty result
malformed date pattern in 'since' or 'edition' — rejected by schema validation
payment failure or insufficient USDC balance — request not fulfilled
no remaining records — returns empty records array with remaining: 0
stale edition requested — may return empty or partial results
