How this service works
Checks caller-supplied HTTP 402 cache and paid-route facts for leakage risk.
Output
Returns a JSON audit result indicating whether the specified x402 route has cache misconfiguration that could expose paid content to unpaid users, including comparison against a reference configuration, specific policy violations detected, and an overall compliance verdict.
Example use cases
Detect CDN cache bypass on paid route
“Audit my x402 payment-gated route '/api/blockchain/wallet-map' for cache leakage — the current response has status 200, cache-control set to 'public, max-age=600', payment_required is false, and cdn_cache_present is true with paid_content_cached also true. Use a reference where cache-control was 'no-store, no-cache' and paid content was not cached.”
Verify correct cache headers after deployment
“After my latest deploy I want to confirm my x402 route '/api/x402/premium-report' isn't leaking — status is 402, cache-control is 'no-store', payment_required is true, cdn_cache_present is false. Check this against the same reference config to make sure nothing regressed.”
Compliance check for x402 route monetization audit
“I need to run a formal cache leakage compliance audit on route '/api/v2/defi-map' — current facts are status 200, cache-control 'private, no-cache', payment_required true, cdn_cache_present false, paid_content_cached false. Reference facts are the same. Flag any policy issues.”
Technical details
Endpoint
POSThttps://api.blockchainmoneymap.com/api/x402/x402-cache-leakage-guard?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need to specifically audit x402-monetized API routes for HTTP/CDN cache misconfiguration that could allow paid content to be served without payment. It is purpose-built for the x402 payment protocol context, making it more targeted than generic HTTP header validators or security scanners when the concern is cache leakage on blockchain-payment-gated endpoints.
Side effects
- Missing required fields (route_path, status_code, cache_control, payment_required_present) returns validation error
- Invalid mode value (not 'audit') returns schema rejection
- Conflicting facts (e.g. free_route_present and paid_content_cached_present both true) may produce ambiguous audit output
- Payment failure via x402 protocol returns 402 with payment details
- Malformed headers object exceeding maxProperties returns schema error
