Try any of our 23 agent APIs free. 19 of them have a preview you can run here in your browser; ToolFit, ToolRoute, FXRate and CryptoPrice run free through MCP (see their cards below). Transcribe has no free tier (paid per call; see Built by us). No wallet, no signup. Previews only run when you press Run. Tools are listed A to Z. Free previews are rate-limited per IP and return a trimmed result; the paid call (USDC over x402, or prepaid credits) returns everything, and you are only charged for a successful answer.
