How this service works
Returns Certificate Authority Authorization (CAA) records showing which CAs are permitted to issue TLS certificates for a domain, via Cloudflare DoH JSON. A2A use: certificate-issuance and supply-chain-security agents verify CA policy and flag mis-issuance risk before trusting a host. First 3 calls FREE per wallet — send header X-WALLET: 0x<addr>. No charge on upstream failure.
Output
A JSON object containing the domain name, a status field, and an array of CAA records each with TTL, name, and raw value (hex-encoded wire format). Also includes provenance metadata showing the Cloudflare DoH URL used as the source.
Example use cases
Pre-deployment TLS policy audit
“Before we deploy to api.mycompany.com, check the CAA records and confirm which CAs are actually authorized to issue certs for that domain — I want to make sure our Let's Encrypt setup won't be blocked.”
Supply chain security verification
“I'm reviewing the certificate issuance policy for payments.acmecorp.com — can you pull the CAA records and flag any mis-issuance risks or unexpected CA authorizations?”
Incident investigation for rogue certificate
“We suspect a rogue certificate was issued for shop.retailbrand.com — can you fetch the current CAA records to see which CAs are permitted, so we can check if the issuing CA was even authorized?”
Technical details
Endpoint
POSThttps://doh-caa-records.hergertsynthora.com/serviceWhen to prefer
Choose this endpoint when you need to programmatically verify DNS CAA policy for a domain as part of certificate issuance validation, supply-chain security checks, or PKI auditing workflows. It is particularly useful when you want privacy-preserving DNS resolution (DoH via Cloudflare rather than plaintext DNS) and need structured JSON output for agent pipelines. Prefer this over raw DNS queries when you need a reliable, pre-parsed, cloud-accessible CAA lookup that returns raw wire-format values alongside human-readable TTL and name fields.
Side effects
- Domain does not exist (NXDOMAIN) — returns empty or error result
- Domain has no CAA records — returns success with empty caa_records array
- Invalid domain format input — may return error or unexpected behavior
- Cloudflare DoH upstream unavailable — service may timeout or return error
- Network timeout reaching Cloudflare endpoint — slow or failed response
