概要

What is Gatefare — paid-API marketplace?

Gatefare — paid-API marketplace is a Model Context Protocol (MCP) server that connects Claude Desktop, Cursor, or any MCP-compatible agent to the Gatefare catalog of paid HTTP APIs. Payments settle as USDC on Base via the open x402 standard, with no SaaS keys, subscriptions, or escrow. It is non-custodial: signing happens locally and the private key never leaves the machine.

How to use Gatefare — paid-API marketplace?

Configure the server in your client’s MCP config (Claude Desktop, Cursor, etc.) using the npx command npx -y @gatefare/mcp. Add optional environment variables like WALLET_PRIVATE_KEY for buying APIs or GATEFARE_PAT for publishing APIs. Tools auto-register based on which environment variables are set.

Key features of Gatefare — paid-API marketplace

  • Non-custodial: private key never leaves your machine
  • USDC settlement on Base via open x402 standard
  • 13 tools across discovery, buyer, publisher, and safety domains
  • Tools auto-register based on environment configuration
  • Runtime budget safety cap (WALLET_BUDGET_USD)
  • Structured error codes for agent retry logic

Use cases of Gatefare — paid-API marketplace

  • Search the catalog and call a paid weather API in one conversation
  • Publish your own HTTP APIs for per‑call USDC pricing
  • Programmatically query and purchase APIs from an MCP‑compatible agent
  • Browse the catalog and estimate costs before buying

よくある質問

1

What networks does Gatefare support?

The default network is `eip155:8453` (Base mainnet). For testing, set `WALLET_NETWORK` to `eip155:84532` (Sepolia testnet).

2

What happens if I don't set a wallet key?

Without `WALLET_PRIVATE_KEY`, only discovery and safety tools are available. Buyer tools (`call_api`, `get_wallet_balance`, `estimate_cost`) are hidden.

3

How are payments secured?

The server signs an EIP‑3009 `transferWithAuthorization` that is single‑use and time‑bounded. The private key is never logged, and the server rejects network confusion attacks by verifying the configured chain.

4

Can I use this without an AI agent?

Yes. For paying x402 APIs from a backend, use Coinbase's official x402 SDKs. To browse the catalog programmatically, use the REST API at `gatefare.io/api/catalog` (OpenAPI 3.1 spec available).

5

What runtime does Gatefare depend on?

The server runs on Node.js via `npx` and is installed from npm as `@gatefare/mcp`. No additional runtime dependencies are required beyond a standard Node.js environment.
