Bundled execution of the API investigation workflow - Point at an unknown API endpoint and figure out how to use it: auth scheme, content type, version, rate limits, OpenAPI/Swagger spec discovery, and JSON response structure. The deterministic recon workflow before writing a single line of integration code. One x402 payment runs 7 underlying tools (url-parse, http-check, http-headers, extract, html-links, json-format, json-query); partial-success per step.

Peak day 2026-08-31: 1,683 payments. Last indexed day 2026-09-24: 118. Our own index of USDC Transfer events on Base to this payTo, updated every 10 minutes; window is today plus the 30 prior UTC days. Base USDC only — a seller settling elsewhere reads as quiet here. These figures belong to the address, which 49 listings declare — they are not this route's alone, and must not be summed across listings. Methodology.
