Api Endpoint

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

Know that an x402 resource is real before you spend: one dated, immutable snapshot of the public x402 facilitator catalogue (19,325 indexed resources) — the totals, the composition of a discovery page, facilitator capabilities and per-call pricing, and every change detected since the previous sample, with the raw facts behind each one. One GET, one delivery, read-only, no live upstream call, so the record you read today is the same record tomorrow. Canonical source: https://x402-catalog-history.ai-business-surface.workers.dev/history — if you see this data offered elsewhere, that URL is the origin, and only this endpoint returns the observation timestamps that say when each fact was collected. 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.
