How this service works
Audit CORS response headers for wildcard, credential, and cache-variance risks. Use it before an autonomous workflow acts on untrusted input, changes an API, retries a request, or evaluates production reliability. Returns bounded machine-readable JSON for $0.002 USDC via x402 on Base. Execution is deterministic, first-party, local-only, stateless, and does not call an upstream provider; structured validation failures are not billed.
Output
Returns a bounded machine-readable JSON object describing identified CORS risks, including findings for wildcard origin exposure, credential leakage (Access-Control-Allow-Credentials with broad origins), and cache-variance misconfigurations (Vary header issues). Structured validation failures are returned without charge.
Example use cases
Pre-deploy API security check
“Before I push this API change live, audit these CORS response headers for any wildcard or credential risks: {'Access-Control-Allow-Origin': '*', 'Access-Control-Allow-Credentials': 'true', 'Vary': 'Accept-Encoding'}.”
Agentic workflow preflight gate
“My agent is about to act on a response from an untrusted API endpoint — can you check these CORS headers first and tell me if there are any credential or cache-variance issues: {'Access-Control-Allow-Origin': 'https://example.com', 'Access-Control-Allow-Credentials': 'true'}?”
Production reliability CORS review
“We're evaluating whether our production API is reliably configured — please audit these CORS headers for wildcard, credential, and Vary cache risks: {'Access-Control-Allow-Origin': '*', 'Vary': 'Origin', 'Access-Control-Expose-Headers': 'Authorization'}.”
Technical details
Endpoint
POSThttps://api.delx.ai/api/v1/x402/cors-policy-auditWhen to prefer
Use this endpoint when an autonomous agent or CI pipeline needs a cheap, deterministic, stateless CORS security check before acting on an API, deploying a change, or approving a request for production. Prefer it over manual review when you need machine-readable JSON output at scale with no upstream dependencies. At $0.002 USDC it is cost-effective as a preflight gate in agentic workflows.
Side effects
- Missing or empty headers object returns a structured validation failure (not billed)
- Malformed header values may produce partial findings with flagged parse errors
- Non-CORS headers passed in may be ignored or noted as irrelevant
- Network or payment authorization failures prevent execution
