YourAITools API › docs
Decision guide: map what your agent needs (pay safely, check a token, scan for prompt injection, read a page, trading research, find a paid API) to a pay-per-call x402 tool, with price, endpoint, curl and MCP example.
How paying works: call the paid URL with no payment and you get HTTP 402 with a PAYMENT-REQUIRED header (x402 v2) and the price. Pay in USDC on Base, Polygon, Arbitrum One or Solana with any x402 client (@x402/fetch, x402-axios, Coinbase AgentKit, x402 Python) and retry. Per call only: no signup, no subscription, no custody. Or buy prepaid credits once (https://api.youraitools.co/credits/) and send Authorization: Bearer <key>. Every tool has a free preview, an OpenAPI doc and a remote MCP server (streamable HTTP) at <tool>/mcp.
MCP client config (any tool): {"mcpServers":{"<tool>":{"url":"https://api.youraitools.co/<tool>/mcp"}}}
