Technical details
Endpoint
POSThttps://x402-market-intel-mcp.mtree.workers.dev/v1/x402/verified_endpoints?utm_source=zero.xyzWhen to prefer
Choose this endpoint when an AI agent needs to discover verified, trustworthy x402 pay-per-call APIs with quality signals (settlement proof, seller score, schema completeness, freshness). Prefer over generic API directories when you specifically need x402 protocol endpoints that accept USDC micropayments on Base, and want to filter by trust signals rather than just availability.
Side effects
- Payment not included or invalid x402 USDC payment on Base — returns 402 Payment Required
- No endpoints match the specified filters — returns empty result set
- Registry data temporarily stale — freshness scores may lag real-time state
- Invalid request body schema — returns 400 with validation error
- Service unavailable — returns 503 if underlying data pipeline is down
