How this service works
Extract issue/issuewild hosts from CAA record texts. Call when inventorying allowed CAs from CAA answers. Returns hosts list as deterministic JSON for $0.001 USDC via x402 on Base. First-party local math only—no RPC, live market feed, API keys, storage, or mediagen. Advisory only; the caller owns capital, risk, and production controls.
Output
Returns a JSON object containing a 'hosts' array of certificate authority hostnames parsed from the input CAA record strings (e.g. ['letsencrypt.org', 'pki.goog']), plus a schema identifier string.
Example use cases
Audit TLS cert issuance policy
“I have a bunch of raw CAA record strings from a domain audit — can you extract all the certificate authority hostnames that are authorized to issue certs from them?”
Verify Let's Encrypt is authorized
“Check these CAA records and tell me if letsencrypt.org appears as an authorized issuer: ["0 issue \"letsencrypt.org\"", "0 issuewild \"sectigo.com\""]”
Normalize CA list from DNS export
“I exported these CAA records from our DNS zone file. Extract just the hostnames of the allowed certificate issuers so I can cross-reference them with our cert inventory.”
Technical details
Endpoint
POSThttps://api.delx.ai/api/v1/x402/caa-issue-hosts?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need to programmatically extract certificate authority hostnames from raw CAA DNS record strings — particularly in infrastructure automation, security auditing, or certificate lifecycle management workflows where parsing CAA records manually would be error-prone.
Side effects
- Malformed CAA record strings may yield empty or partial hosts array
- Records without an 'issue' or 'issuewild' tag may produce no hosts
- Non-array or missing 'records' field causes request validation failure
- Records with semicolons or non-standard formatting may be included literally in the output
