API docs

Every tool works over MCP (https://aipaygen.com/mcp) and HTTP (GET with query parameters or POST with a JSON body to /v1/<tool>).

Authentication and payment

Send Authorization: Bearer apg_… to pay from prepaid credits. Create a key with POST /v1/keys. Without a key, paid endpoints answer 402 Payment Required with a PAYMENT-REQUIRED header (x402 v2). Retry with a PAYMENT-SIGNATURE header; the receipt comes back in PAYMENT-RESPONSE. Over MCP, the payment goes in _meta["x402/payment"].

Successful responses look like {"tool": "...", "data": {...}, "receipt": {...}}. Errors look like {"error": {"code": "...", "message": "..."}}.

search_marketplace

Search 19,000+ AI-agent resources: AIPayGen's paid tools, 11,000+ third-party APIs (with docs and auth info, many x402-payable), 1,500+ MCP servers, 3,900+ reusable skills, 950+ registered agents and 1,500+ agent services. Free.
