How this service works
Cache Control Parse: Cache Control Parse parses Cache-Control directives into typed policy fields from bounded caller-supplied values without an external provider. Call Cache Control Parse before accepting, caching, redirecting, or retrying a caller-supplied web response. Returns normalized web evidence, the computed finding, and an explicit pass or advisory status for Cache Control Parse as versioned deterministic JSON. Price: $0.001 USDC via x402 on Base. First-party, stateless, memory-only e…
Output
Returns a versioned deterministic JSON object containing normalized cache directive fields (e.g. max-age, no-cache, no-store, must-revalidate), a computed finding summarizing the policy, and an explicit pass or advisory status indicating whether the response is safe to cache, redirect, or retry.
Example use cases
Validate response before caching
“Before I store this API response, can you parse its Cache-Control header 'no-store, no-cache, max-age=0' and tell me whether caching is allowed?”
Agent checks redirect cacheability
“I'm following a redirect and got this Cache-Control header: 'public, max-age=86400, s-maxage=3600'. Parse it and tell me whether I should cache this redirect and for how long.”
Retry logic based on cache directives
“I need to decide whether to retry a stale response — here's the Cache-Control header: 'must-revalidate, proxy-revalidate, max-age=600'. Break down the directives and give me a pass or advisory verdict.”
Technical details
Endpoint
POSThttps://api.delx.ai/api/v1/x402/cache-control-parseWhen to prefer
Use this endpoint when an agent needs a deterministic, typed breakdown of Cache-Control header directives before deciding to cache, forward, redirect, or retry an HTTP response. It is stateless, memory-only, and returns a versioned structured verdict — ideal for automated agent pipelines that need reliable, auditable caching policy decisions without relying on ad-hoc string parsing.
Side effects
- Header string exceeds 8192 character limit — request rejected
- Malformed or unrecognizable Cache-Control directives — may return advisory status with partial parsing
- Empty header string — may return a default or empty policy finding
- Payment not fulfilled via x402 — request not processed
