How this service works
Where to list an MCP server, x402 API, AI agent or skill - the whole edition of places checked by us, all 5 sections (free and working, paid, backlink only, lists you by itself, broken), for $0.99. With a personal access token: the newest edition for 30 days, then the edition you bought, forever (JSON or Markdown). Each record: how to submit and how to check you are listed. Same service per record: POST /v1/places/next at $0.01 per record. Free index: GET /v1/places
Output
A JSON object containing: a list of up to ~93 directory/catalog records (each with name, domain, submit URL, auth method, submission form type, review process, section classification, and a check URL to verify listing); the current edition date; an access token with expiry for 30-day fresh updates; a receipt with settlement transaction; and section labels (e.g. 'Checked, free to list, working', 'Broken').
Example use cases
Launch-day MCP server promotion
“I just published an MCP server and want to get it listed everywhere possible — can you pull the full AISkills402 directory catalog so I know every place to submit it, whether they're free or paid, and how to check I'm actually listed?”
Auditing broken or dead submission sites
“Before I spend time submitting my x402 API to directories, can you fetch the complete AISkills402 places catalog so I can see which sites are broken or non-functional and skip them?”
Building a submission checklist for an AI agent
“I'm launching an AI agent and want a structured checklist of every catalog and registry that indexes agents — pull the full AISkills402 directory catalog with submission instructions for each record so I can work through them one by one.”
Technical details
Endpoint
GEThttps://api.aiskills402.com/v1/places/all?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need the complete, curated, human-checked list of every place to submit an MCP server, x402 API, or AI agent — including broken and paid-only entries that free indexes omit. Use the free GET /v1/places for a partial index, and POST /v1/places/next at $0.01/record to page through records individually. This endpoint is the right choice when you want all sections in one call for a one-time $0.99 fee.
Side effects
- Payment not settled — returns 402 with payment requirements if USDC payment header is missing or invalid
- Token expired — if personal access token is past the 30-day update window, returns the edition at purchase time rather than current
- No records returned — if catalog is empty or unavailable, count may be 0
- Network timeout — if the upstream catalog build takes too long
- Invalid method — HEAD requests return headers only, no body
