How this service works
Audit JWT claim names, expiry, and identifiers at an explicit reference time without returning claim values. Use it as a bounded preflight or analysis step inside an enterprise agent workflow before data, policy, integration, security, or commercial decisions reach production. Returns deterministic machine-readable JSON for $0.003 USDC via x402 on Base. Execution is first-party, local-only, stateless, memory-only, and has no paid upstream or input retention. Results are advisory; the caller rem…
Output
Returns deterministic machine-readable JSON listing the JWT claim names present, expiry evaluation result relative to the provided reference epoch, and identified identifier fields — without revealing any claim values. No data is retained or logged.
Example use cases
Preflight JWT before policy enforcement
“Before we apply our data-sharing policy, audit the JWT claims object I'm passing you — check the claim names, expiry, and any identifiers as of epoch 1719800000, but don't reveal the actual claim values.”
Detect expired tokens in integration pipeline
“I need to know if this JWT is expired relative to epoch 1718000000 — audit its claim names and expiry status so we can decide whether to reject it before it hits our integration layer.”
Security review of JWT structure
“Can you inspect the structure of this JWT claims object and tell me what claim names and identifiers are present, evaluated at epoch 1720500000, without exposing the values themselves?”
Technical details
Endpoint
POSThttps://api.delx.ai/api/v1/x402/jwt-claims-auditWhen to prefer
Choose this endpoint when you need a stateless, privacy-preserving preflight audit of JWT claim metadata — specifically when you must not expose claim values, when you need deterministic expiry evaluation at an explicit reference time, or when integrating a lightweight JWT structure check into an enterprise agent workflow before a security, policy, or access-control decision.
Side effects
- Missing or malformed claims object returns a validation error
- Invalid or missing now_epoch causes evaluation to fail or default unexpectedly
- Malformed JWT structure may result in parse errors
- Payment failure via x402 prevents execution
- Empty claims object returns minimal audit with no fields found
