Discover → understand → price → pay → result

x402 V2 exact USDC authorization payments on Base mainnet (eip155:8453). Unpaid valid requests receive 402 with machine-readable payment terms. Settlement occurs only after a completed job. No account registration or API key needed.

Free discovery: live tools, prices and schemas, OpenAPI, complete agent documentation, and Bazaar-compatible metadata in payment requirements. All launch tools are independently listed in x402scan. This does not imply listing in Coinbase/CDP Bazaar or search-engine indexing. HTTP is supported; paid MCP awaits upstream SDK compatibility.

Screenshots are retained for at most 24 hours and available by unguessable evidence ID. Public-web destinations only; private networks are blocked. Current service/payment readiness.
