How this service works
Decode JWT payload claims without signature verify. Call when inspecting exp/iat for debugging (untrusted decode). Returns claims and exp_human if present as deterministic JSON for $0.001 USDC via x402 on Base. First-party local math only—no RPC, live market feed, API keys, storage, or mediagen. Advisory only; the caller owns capital, risk, and production controls.
Output
Returns a JSON object containing the decoded JWT claims (e.g. exp, sub) as-is, plus a human-readable ISO 8601 string for the expiry timestamp (exp_human), and a schema identifier. No signature verification is performed.
Example use cases
Debug expired auth token
“I have this JWT from an API response and I want to know if it's expired and what the expiry date looks like in plain English — can you decode it and show me the claims? Token: eyJhbGciOiJIUzI1NiJ9.eyJzdWIiOiJhZ2VudF80MiIsImV4cCI6MTcwMDAwMDAwMH0.sig”
Inspect user identity in token
“Take this JWT and tell me what's inside it — specifically who the subject is and when it expires: eyJhbGciOiJSUzI1NiJ9.eyJzdWIiOiJ1c2VyXzc3NyIsImV4cCI6MTcyMDAwMDAwMH0.sig”
Validate token freshness in workflow
“I'm building an agent workflow that needs to check whether a token is still valid. Can you parse this JWT and tell me its expiry as a readable timestamp so I can compare it to now? eyJhbGciOiJIUzI1NiJ9.eyJleHAiOjE3NTAwMDAwMDAsInN1YiI6InN2Y19ib3QifQ.sig”
Technical details
Endpoint
POSThttps://api.delx.ai/api/v1/x402/jwt-claims-humanizeWhen to prefer
Choose this endpoint when you need a quick, lightweight decode of a JWT's payload claims — especially to humanize the exp timestamp — without caring about signature verification. Ideal for debugging, logging, or agent workflows that need to inspect token metadata (subject, expiry) before deciding whether to re-authenticate. Prefer this over full JWT verification libraries when you don't have the secret/public key available or when signature validity is handled elsewhere.
Side effects
- Malformed JWT string (not three dot-separated base64 segments) — returns parse error
- Missing jwt field in request body — validation error
- JWT with no exp claim — exp_human field may be absent or null
- Network timeout — retry with same input
- Payment failure — 402 response if USDC balance insufficient
