shallowio.github.vanakenj45/x402-agent-api · Verify this server
Free, no payment needed. Returns a paid tool's real, live answer to its documented example input (refreshed every 5 minutes to 6 hours depending on the tool), the price of a call with your own input, and where to send it. With no `tool`, lists every paid tool with the URL of its sample. Use it to check a tool's output format and quality before paying, or to test an integration. Also answers GET, e.g. /api/v1/samples?tool=token_risk_check. Rate-limited per client.
