How this service works
Pay-per-result APIs for agents. No signup. Exact price. Verifiable delivery. USDC on Base + Solana via x402.
Output
A JSON object with a top-level pass/fail status, the parsed max_age_seconds, whether includeSubDomains is present, a SHA-256 hash of the input for auditability, a confirmation that no data was retained and no external calls were made, and the operation identifier 'web_reliability:hsts_policy_check'.
Example use cases
Pre-deployment HSTS compliance audit
“Before I deploy my new site, validate this HSTS header — 'max-age=31536000; includeSubDomains' — and confirm it meets a minimum of 31536000 seconds with subdomains required.”
HSTS preload eligibility check
“I want to submit my domain to the HSTS preload list. Can you check this header 'max-age=63072000; includeSubDomains; preload' and confirm it passes with a minimum max-age of 10886400 and subdomains required?”
Security header regression test in CI
“As part of my automated security checks, verify that this HSTS response header from my staging server — 'max-age=86400' — passes a policy requiring at least 86400 seconds but without requiring subdomains.”
Technical details
Endpoint
POSThttps://commerce.delx.ai/api/v1/x402/hsts-policy-check?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need a deterministic, auditable, no-signup HSTS header policy check paid per-call in USDC without storing your data. Prefer it over rolling your own parser when you need a verifiable evidence trail (input hash, zero external calls, no retention) or when running inside an autonomous agent workflow that needs a lightweight, pay-as-you-go security validation step.
Side effects
- Header string missing or empty — validation cannot proceed
- max-age value in header is below the specified minimum_seconds threshold — returns passed:false
- includeSubDomains directive absent when require_subdomains is true — returns passed:false
- Malformed or unparseable HSTS header string — may return an error or failed parse result
- Header exceeds 8192 character limit — rejected by schema validation
