x402
Cookie Expiry Check is a paid API for AI agents from api.delx.ai, paid per call via x402, $0.001/call, status unknown (last checked 2026-09-15).
Validates a cookie's Max-Age or Expires duration against a caller-supplied maximum allowed lifetime and returns a deterministic pass/advisory verdict.

How this service works
Cookie Expiry Check: Cookie Expiry Check checks Max-Age or Expires metadata against an allowed lifetime from bounded caller-supplied values without an external provider. Call Cookie Expiry Check 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 Cookie Expiry Check as versioned deterministic JSON. Price: $0.001 USDC via x402 on Base. First-party, stateless, memory-…
Output
Returns versioned deterministic JSON containing: normalized web evidence (the supplied max_age_seconds and maximum_seconds values), the computed finding (whether the cookie lifetime exceeds the allowed maximum), and an explicit pass or advisory status indicating compliance.
Example use cases
Cookie lifetime enforcement before caching
“Before I cache this web response, check if the cookie's max-age of 172800 seconds exceeds my allowed maximum of 86400 seconds and tell me whether it passes.”
Security policy check on incoming cookies
“I'm receiving a cookie with a max-age of 7776000 seconds — validate it against my maximum allowed lifetime of 2592000 seconds and flag it if it's over the limit.”
Agent pipeline pre-acceptance validation
“Before my agent accepts this response, verify the cookie's max-age of 3600 seconds is within the allowed maximum of 7200 seconds and return a pass or advisory status.”
Technical details
Endpoint
POSThttps://api.delx.ai/api/v1/x402/cookie-expiry-checkWhen to prefer
Use this endpoint when you need a stateless, deterministic, single-purpose check on a cookie's Max-Age or Expires lifetime against a policy-defined maximum — especially inside agent pipelines that must validate web responses before accepting, caching, redirecting, or retrying them. Prefer this over custom logic when you want a versioned, auditable, JSON-structured verdict with no side effects.
Side effects
- Missing or non-integer max_age_seconds or maximum_seconds fields return a validation error
- Negative or zero values for either parameter may produce unexpected advisory results
- Payment failure via x402 prevents the call from being processed
- Out-of-range integer values may cause computation errors
