DANE Record Validator API

About the DANE Record Validator API

Includes validation of certificate data format, length verification, and security level assessment with recommendations for optimal DANE configuration.

What people use it for

DANE Configuration

Validate DANE/TLSA record configuration to ensure proper certificate association and DNS security implementation

Authentication Audit

Audit DNS-based authentication of named entities (DANE) for email servers and web services security compliance

Security Scanning

Build DNS security scanning tools that validate TLSA records for certificate pinning and trust anchor verification

Certificate Pinning

Verify certificate pinning implementation using TLSA records to protect against man-in-the-middle attacks and CA compromise

Request parameters — POST /v1/danevalidator

Sent as JSON in the request body. Premium parameters are accepted on every plan but only take effect on plans that include them. Anything not listed here is dropped rather than passed through.

curl -X POST "https://api.apiverve.com/v1/danevalidator" \
  -H "x-api-key: YOUR_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{"record":"_443._tcp.example.com. 86400 IN TLSA 3 1 1 0123456789ABCDEF0123456789ABCDEF0123456789ABCDEF0123456789ABCDEF"}'

Authentication

Send your key in the x-api-key header. That is the only auth step — no token exchange, and no per-endpoint scope to configure.

Response — POST /v1/danevalidator

Every APIVerve endpoint returns the same three top-level keys, so one response handler covers your whole integration: status, error and data. Only data changes shape.

Response fields

Paths are relative to data. Premium fields are absent rather than zeroed on plans that do not include them, so check for presence instead of comparing to 0.

Response headers

Every response carries your balance, so your own code always knows where it stands without polling anything. All four are exposed to browsers through CORS.

Errors

Read the HTTP status first, then error for the specific reason. The body names the parameter that has to change.

What a call costs — 2 credits per call

Credits are shared across every APIVerve API — one balance, one key, one bill. Failed requests never count against it, so a rejected input costs nothing.

Calls are what the credits buy at this API's rate — spend them here, on any of the other APIs, or across both. Nothing is reserved per endpoint.

Zero-code embed — one snippet, no backend

Drop an interactive DANE Record Validator form onto any page. The widget calls the API for you, so no key ever appears in your markup and there is nothing to deploy.

Changelog — DANE Record Validator API

Every change to this endpoint, newest first. Breaking changes ship as a new version and the previous one keeps serving — response fields are added, never removed or retyped in place, so an integration written against v1 keeps working.
