Api Endpoint

x402-catalog-history.ai-business-surface.workers.dev

See what moved in the x402 catalogue over the period you choose: for every field, the value before and after, the observation time and the target it belongs to — plus where observation stopped, where it resumed and which cycles are missing. One GET, one delivery, read-only, no live upstream call. A purchase is two calls by design: this first call returns 402 with the price and the payment terms, and you then repeat the same request with the PAYMENT-SIGNATURE header to receive the 200 delivery.
