Api Endpoint

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

The observed x402 catalogue is mass-produced: one GET returns every repeating description template, how many resources share it, the axis it varies along and a representative example — 30 families, largest 80 members, computed from 2562 observed resources (2400 with a description). curl: GET /catalog/families (optional min_members>=2, axis=tld|selector|domain|number|url|literal|token|none, limit=1-200). Response: {"count":30,"max_members":80,"axis_counts":{"selector":1,"token":17,"none":10,"tld":1,"domain":1},"families":[{"family_id":"fam-001","members":80,"axis":"selector","axis_values":["sendgrid._domainkey.","namecheap._domainkey.","marketo._domainkey."],"template":"dkim public key selector <q> domain looks <var> <var> <var> <var> <var> <var> <var> <var> <var> <var> <var> <var> <var> ","price_usd":{"min":0.01,"median":0.01,"max":0.01},"representatives":[{"resource":"https://dns.intel.rallylive.ca/dns/dkim/ionos","description":"DKIM public key for selector \"ionos\" of a domain: looks up ionos._domainkey.<domain> (TXT, Cloudflare DoH) and parses v="}]}]}. 0.05 USDC, no account, no key, one GET, one delivery. 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.
