No API key and no initialize handshake required. Paid tools return structured HTTP 402 / x402 payment challenges (USDC on Base; testnet during the current private beta) — settle and retry the resource with an X-PAYMENT / PAYMENT-SIGNATURE header.

Notes

Machine-to-machine only. Human browsers receive a plain-text 402 by design.
Status: closed private beta. Endpoints, pricing and datasets may change.
Source of the gateway lives in a private repository; this repo hosts the public MCP documentation and registry manifest.
