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 schema 'delx/util-http-header-diff/v1' containing: 'added' (list of newly added headers), 'removed' (list of deleted headers), 'changed' (list of headers with name, before value, and after value), 'unchanged_count' (integer count of unchanged headers), 'security_sensitive_changes' (list of header names considered security-sensitive that changed), and 'credential_values_redacted' (boolean indicating if credential-like values were masked).
Example use cases
Post-deployment security header audit
“After we pushed the new config, the server headers changed. Can you diff the old headers (content-type: text/html, strict-transport-security: max-age=60, x-frame-options: DENY) against the new ones (content-type: text/html, strict-transport-security: max-age=31536000) and tell me what security-relevant things changed?”
CI pipeline header regression check
“In our CI pipeline we captured headers before the release and after — the before set is content-type: application/json, cache-control: no-store, and the after set is content-type: application/json, cache-control: public, max-age=3600. Show me what changed and flag anything security-sensitive.”
Monitor HSTS policy changes over time
“I want to track whether our HSTS header settings changed between yesterday's snapshot and today's — before was strict-transport-security: max-age=86400 and after is strict-transport-security: max-age=31536000; includeSubDomains. What's different and is it a security-sensitive change?”
Technical details
Endpoint
POSThttps://commerce.delx.ai/api/v1/x402/http-header-diff?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a structured, security-aware diff of two HTTP header snapshots with automatic redaction of credential-like values and explicit flagging of security-sensitive header changes. Ideal for deployment pipelines, monitoring agents, and security audits where a simple text diff would miss security context.
Side effects
- Invalid or non-object input for 'before' or 'after' fields returns an error
- Exceeding 200 properties in either object may be rejected
- Payment not processed — USDC payment via x402 required before result is returned
- Malformed header values may cause unexpected diff results
