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 validated result value, a boolean 'accepted' flag, a 'pass' or 'fail' status, the operation name, and an evidence block containing the SHA-256 hash of the input, a flag confirming no data was retained, and the count of external calls made (zero, indicating pure in-memory processing).
Example use cases
Security header audit for a web app
“I want to audit my web app's security headers — can you check if 'nosniff' is a valid and compliant value for the X-Content-Type-Options header?”
CI pipeline header compliance check
“In my CI/CD pipeline, I need to verify that the X-Content-Type-Options header value 'nosniff' passes security validation before we deploy — can you run that check?”
Security checklist verification for a client site
“I'm reviewing a client's site security checklist — can you validate whether the X-Content-Type-Options header is set to an accepted value like 'nosniff'?”
Technical details
Endpoint
POSThttps://commerce.delx.ai/api/v1/x402/x-content-type-options-check?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a lightweight, verifiable, pay-per-call check of an X-Content-Type-Options header value without setting up an account or long-term subscription. It is ideal for automated agents, CI pipelines, or security audits that require cryptographic evidence of the result (input SHA-256) and guaranteed no data retention — distinguishing it from general-purpose HTTP header scanners or full website security scanners.
Side effects
- Invalid or malformed input string may return a fail status with accepted=false
- Value exceeding 8192 character maxLength will be rejected
- Missing or empty 'value' field may cause a validation error
- Network or payment processing failure may result in no response
