DNS DS Record Shape Check
x402
DNS DS Record Shape Check is a paid API for AI agents from api.delx.ai, paid per call via x402, $0.001/call, status unknown (last checked 2026-09-14).
Validates the structural shape of a DNS DS (Delegation Signer) record by checking key tag, algorithm, digest type, and hex digest format against expected constraints.

How this service works
DNS DS Record Shape Check: DNS DS Record Shape Check checks DS key tag, algorithm, digest type, and hex digest shape from bounded caller-supplied values without an external provider. Call DNS DS Record Shape Check before accepting, caching, redirecting, or retrying a caller-supplied web response. Returns normalized web evidence, the computed finding, and an explicit pass or advisory status for DNS DS Record Shape Check as versioned deterministic JSON. Price: $0.001 USDC via x402 on Base. First-…
Output
Returns a versioned deterministic JSON object containing the normalized DS record evidence, a computed structural finding (e.g. which fields passed or failed shape checks), and an explicit pass or advisory status indicating whether the DS record is well-formed.
Example use cases
DNSSEC delegation record pre-acceptance check
“Before I cache this DS record from the registrar response, can you validate its shape — key tag 45123, algorithm 13, digest type 2, and the hex digest string I got back? I want to confirm it's well-formed before storing it.”
Automated DNS pipeline record sanity check
“I'm processing DS records submitted by users for their domains. Run a shape check on this one: '60485 5 1 2BB183AF09FEA15D2F2B1E88F8DB4B1D6E5B0A13' — tell me if it passes or has any advisory issues.”
DNSSEC configuration validation before redirect
“We're about to redirect traffic based on a caller-supplied DS record. Can you verify the record '20326 8 2 E06D44B80B8F1D246169A9BBDE71D57B4F96A9B5' has a valid structure — correct algorithm, digest type, and hex digest shape — before we proceed?”
Technical details
Endpoint
POSThttps://api.delx.ai/api/v1/x402/dns-ds-record-shape-checkWhen to prefer
Choose this endpoint when you need a deterministic, no-external-dependency structural validation of a DNS DS record before accepting, caching, or acting on it in an automated pipeline. It is ideal for agent workflows that must verify caller-supplied DNS data at low cost ($0.001 USDC) without trusting external DNS resolvers or validators.
Side effects
- Record string exceeds 8192 character limit — request rejected
- Malformed input that cannot be parsed into DS record fields — advisory or fail status returned
- Missing required fields in the DS record string — finding flags specific absent components
- Invalid hex digest characters detected — advisory status with finding detail
- Payment not included or insufficient — x402 payment required error
