ontarioprotocol.com/api/x402/list-service

List your paid x402 API for agent discovery: a 0.50 USDC Bazaar Launch Passport with a live readiness scan, a five-query Coinbase Bazaar retrieval audit with a rank table, a public profile with a signed JSON twin, a badge, MCP/catalog copy, and 30 days of maintenance with day-7 and day-30 Bazaar re-checks for a Base USDC endpoint. Validation is free. The fee covers evidence processing and publication, not placement, ranking, buyers, or safety.
