Action402 or paid webhook execution
Also try pay per API call, agent action relay, x402 webhook receipt, Slack webhook x402, or Zapier webhook x402.
MCP and Bazaar
Discovery-first instructions for agents.
Action402 publishes enough metadata for MCP/Bazaar clients to find the paid route, inspect price and schema, call through x402, then verify the receipt.
Agent flow
Search, inspect, call, verify.
Do not hard-code a hidden route if your client supports discovery. Search by task phrase, inspect the returned x402 metadata, then use the returned route.
Read price, network, schema, tags
Use /api/bazaar, /api/capabilities, and /openapi.json to check contract and budget.
Pay once through x402
Send url, method, optional headers/body, idempotencyKey, retry, and timeout.
Check the proof report
Use returned links.job, links.receipt, or the verify endpoints before marking the action complete.
