Delx Commerce DNS TTL Budget Check
x402
Delx Commerce DNS TTL Budget Check is a paid API for AI agents from commerce.delx.ai, paid per call via x402, $0.001/call, status unknown (last checked 2026-10-01).
Validates whether a set of DNS TTL values fall within a specified minimum/maximum budget policy, returning pass/fail status and out-of-policy entries.

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 a pass/fail status, a list of out-of-policy TTL values, the maximum and minimum TTL observed across the input array, and evidence metadata including a SHA-256 hash of the input and confirmation that no data is retained and no external calls were made.
Example use cases
Pre-deployment DNS policy audit
“Before we push this infrastructure change, check that all our DNS TTLs — 60, 300, 900, 3600, and 86400 — comply with our policy: minimum 60 seconds and maximum 3600 seconds. Tell me which ones fail.”
Web reliability compliance check
“I have a list of TTL values from our DNS records: 30, 120, 600, 7200. Our reliability policy requires all TTLs to be between 120 and 3600. Are any of these out of policy?”
Automated agent DNS budget guard
“Run a DNS TTL budget check on these values from the latest zone file — 60, 300, 1800, 86400 — with a minimum of 60 and maximum of 1800, and report any violations with a verifiable result.”
Technical details
Endpoint
POSThttps://commerce.delx.ai/api/v1/x402/dns-ttl-budget-check?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need a lightweight, verifiable, pay-per-use check of DNS TTL compliance against policy bounds with no signup or persistent data storage. Ideal for autonomous agents that need cryptographic evidence of result integrity (SHA-256 input hash, zero external calls) rather than a self-hosted validation script.
Side effects
- Missing required fields (ttls array not provided) — likely 400 error
- TTL array exceeds 256 items — rejected due to maxItems constraint
- Non-integer values in TTL array — schema validation failure
- Payment failure via x402 — 402 response requiring USDC payment on Base or Solana
