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 three keys — 'added', 'changed', and 'removed' — each containing the Cache-Control directives that were added, modified (with before/after values), or removed between the two input strings. Also includes operation status, whether inputs were retained (always false), and an SHA-256 hash of the input for auditability.

Example use cases

Deployment cache config audit

“I just deployed a new version of our site and I need to know what changed in the Cache-Control header — before the deploy it was 'public, max-age=300' and now it's 'private, max-age=60'. What directives were added, removed, or changed?”

CDN configuration regression check

“Can you diff these two Cache-Control values for me? The old one is 'public, s-maxage=3600, stale-while-revalidate=60' and the new one is 'public, s-maxage=7200'. I want to see exactly what directives got added, removed, or modified.”

Cache policy compliance verification

“I need to verify our Cache-Control header was updated correctly — it should have dropped 'public' and added 'no-store'. The before value is 'public, max-age=300' and the after is 'no-store, max-age=300'. Can you confirm what actually changed?”

When to prefer

Choose this endpoint when you need a structured, machine-readable diff of two Cache-Control header values with verifiable, auditable output (SHA-256 hash, no data retention). Ideal for agents automating deployment checks, CDN config audits, or compliance verification where deterministic, pay-per-call pricing and cryptographic evidence of processing are desirable.

Side effects

Malformed or non-standard Cache-Control directive strings may produce unexpected diff results
Inputs exceeding 8192 characters will be rejected
Missing 'before' or 'after' fields may cause a validation error or empty diff
Payment failure via x402 protocol will prevent execution
