Mcp Server
Gives your AI agent access to Gatefare's catalog of paid HTTP APIs with USDC micropayments settling on Base via the x402 standard. Discovery tools let you search and filter APIs by price or category without a wallet. Add a private key and you get buyer tools that handle the full payment flow: estimate costs, check your balance, and make paid calls where the server signs EIP-3009 transfers locally and retries after 402 challenges. Publisher tools require a personal access token and let you register new APIs, update pricing, check revenue, and trigger on-chain payouts. The wallet budget cap is a runtime safety net, and all signing happens client-side so your key never leaves the machine. If you're building a backend integration instead of an agent workflow, you want Coinbase's x402 SDKs directly.
