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.

      I built this local stdio MCP adapter to discover, preview, and purchase live agent data APIs, including vendor risk, company intelligence, transaction preflight, and EVM reads. Free discovery and previews require no wallet. Optional paid calls settle in Base USDC through x402 v2; auto-pay is disabled by default.
