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.
