How this service works
Pay-per-result APIs for agents. No signup. Exact price. Verifiable delivery. USDC on Base + Solana via x402.
Output
Returns a JSON object with the TLSA record split into its component fields (usage, selector, matching type, certificate data), a boolean indicating whether the shape is valid, an overall status ('pass' or 'fail'), and evidence metadata including a SHA-256 hash of the input and confirmation that no data is retained or external calls made.
Example use cases
Pre-publish TLSA record validation
“Before I add this TLSA record to my zone file, check that '2 0 1 abc123def456...' is properly formatted and has all the right fields.”
Debugging a DANE configuration
“I'm getting DANE validation errors — can you check if my TLSA record '3 1 2 deadbeef...' is even the right shape, so I can rule out a formatting mistake?”
Automated certificate rollover verification
“I just generated a new TLSA record for my mail server. Can you confirm this string has valid TLSA structure before I deploy it: '3 0 1 1234567890abcdef...'?”
Technical details
Endpoint
POSThttps://commerce.delx.ai/api/v1/x402/dns-tlsa-record-shape-check?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need a lightweight, pay-per-call, no-signup check of DNS TLSA record formatting without sending data to a persistent backend. It is ideal for agents performing DANE configuration validation, pre-deployment sanity checks, or certificate rollover workflows where privacy (no data retention) and verifiable delivery matter.
Side effects
- Malformed or empty record string returns shape_valid: false with field parse details
- Record exceeding 8192 characters may be rejected
- Non-TLSA formatted strings will fail shape validation with status 'fail'
- Network or service errors may return HTTP 5xx
