POST /new-x402-listings is charged $0.01 via x402 (Base Sepolia TESTNET, not real funds); the MCP tool is currently free -- see README. Payment settles BEFORE this handler runs: a call that 422s (invalid request body) is still charged, same as a 200. Underlying registration data is 402index.io's own free public API (https://402index.io/api-docs) -- this service does not have exclusive access to anything; its value is polling/dedup/filtering convenience over 402index's ~96k+ entry catalog, not raw data access."}}
