Api Endpoint

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

Buy the period once instead of ten times: up to 100 counted units of detected change in one 0.10 USDC GET (single-change calls cost 0.02 each, so this is the same data for half the price at 10 units and better after that). One unit = one target x one field x one detected change inside the period you pass, from the stored x402 catalogue observations. The response states units_requested, units_delivered and the unit definition, and when fewer units exist it says why — separating fields that were observed and did not change from fields whose target is missing observation cycles. 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.
