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 containing the parsed Cache-Control directives (e.g. public, max-age, stale-while-revalidate) as structured key-value pairs, a cacheable_hint boolean indicating whether the response is likely cacheable, the operation name, processing status ('pass'), and an evidence block confirming no input retention and zero external calls, plus a SHA-256 hash of the input for verifiability.
Example use cases
CDN cache policy audit
“I'm auditing our CDN configuration — can you parse this Cache-Control header and tell me whether the response is publicly cacheable and what the max-age is? Header: 'private, no-store, max-age=0'”
Debugging stale content issues
“We're seeing stale content being served — can you parse this Cache-Control header and extract the stale-while-revalidate and max-age values so I can figure out the caching window? Header: 'public, max-age=600, stale-while-revalidate=60, stale-if-error=3600'”
Validating API response cacheability
“Before we deploy this API endpoint, can you check if this Cache-Control header actually allows caching? Header: 'no-cache, must-revalidate'”
Technical details
Endpoint
POSThttps://commerce.delx.ai/api/v1/x402/cache-control-parse?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a lightweight, pay-per-call, no-signup way to parse Cache-Control headers into structured data with verifiable, privacy-preserving processing (no retention, SHA-256 evidence). Ideal for agents running automated web reliability checks, CDN audits, or HTTP response analysis pipelines where predictable $0.001 USDC pricing and auditability matter. Prefer over rolling your own parser when you need the evidence/audit trail or are operating in a crypto-native payment environment using x402/USDC on Base or Solana.
Side effects
- Header string exceeds 8192 character limit — request rejected
- Malformed or unrecognized Cache-Control directives may not appear in output directives map
- Empty header string returns empty directives with cacheable_hint false
- Payment not received or insufficient USDC — 402 response returned before processing
