List your x402/MCP tool in one API call

POST https://api.youraitools.co/listing/v1/submit with name, url (or endpoint), payTo, category and a manifest (mcp or x402). No signup, no captcha.

# x402 API: name, url (or endpoint), payTo, category, manifest. No signup, no captcha.
curl -s -X POST https://api.youraitools.co/listing/v1/submit \
  -H 'content-type: application/json' \
  -d '{"name":"Weather Now","url":"https://api.example.com","payTo":"0xYourOwnWallet","category":"data","description":"Current weather for any city, paid per call over x402.","manifest":{"type":"x402","resources":[{"path":"/v1/weather","method":"GET","price":"$0.001"}]}}'

# MCP server: same call with manifest {"type":"mcp"}
#   {"name":"Doc Search MCP","endpoint":"https://mcp.example.com/mcp","payTo":"0xYourOwnWallet","category":"search","manifest":{"type":"mcp"}}

# HTTP 202:
# {"id":"…","status":"screening","slug":"…","status_url":"https://api.youraitools.co/listing/v1/submit/…","poll_after_seconds":…,"gateway_url_when_approved":"https://api.youraitools.co/g/<slug>/…"}

It returns 202 with id, status: "screening", slug, status_url, poll_after_seconds and gateway_url_when_approved. Poll the status (free):

curl -s https://api.youraitools.co/listing/v1/submit/<id>
# status: screening → pending_review → approved | rejected (an approved listing can later be suspended)

Statuses: screening, pending_review, approved, rejected, suspended. Approved listings are served at /g/<slug>/… (x402) and /g/<slug>/mcp on api.youraitools.co.

Fees

• Free to submit, 0% cut.
• Buyers pay your registered payTo directly through your own 402s; we never hold funds.
• If a listing’s 402 points to a different wallet, the call is blocked and the listing suspended.
• Optional, live: a paid Featured slot in the gateway directory, $29 for 30 days, with at most 6 Featured slots at a time. It is labeled “Featured” and kept apart from the main list, whose order payment never changes. Pay in USDC over x402 (POST https://api.youraitools.co/listing/v1/featured with gateway_slug and contact_email) or by card (POST the same body to /listing/v1/card/featured). The slot starts only after your listing passes our checks again; if it doesn’t, you get a full refund. Refund and pause rules are in our terms. Listing stays free and 0% cut either way.

Screening

• A health check, a prompt-injection scan, OFAC/scam screening of your payTo, and SSRF and duplicate checks.
• Your first listing is reviewed by a person. Later clean listings from the same payTo are approved automatically.
• Limit: 5 submissions a day per payTo.

Spec: submit openapi.json · Directory of approved listings: /g/ (new, so it starts empty) · Stats: /stats/v1/tools/gateway

One MCP server for every YourAITools tool

Add https://api.youraitools.co/mcp/hub to Claude, Cursor or any MCP client. You get 45 tools: OFAC screening, token and counterparty safety, prompt-injection and leak scans, web-to-Markdown, perp and TA data, an x402 endpoint doctor, tool-list audits and task-to-tool routing, currency conversion on ECB reference rates, crypto price snapshots, and more.

• No account and no signup. 38 of the 45 tools have a free tier; the rest are paid per call.
• Paid calls: prepaid credits (card or USDC) or x402 in USDC on Base, Polygon, Arbitrum One or Solana.
• Same price as calling the tool directly. The hub adds no fee.
• Failed tool calls aren’t charged: credits are refunded automatically, and x402 payments settle only after a successful response.
• Live usage, uptime and latency are public at /stats/v1/tools (hub: /stats/v1/tools/mcp-hub).
