How this service works
Pay-per-call tools for AI agents: any document to clean Markdown (PDF, Word, Excel, PowerPoint, web pages); US company fundamentals, SEC filings and insider trades; Treasury yields; FRED macro data; official FX rates (ECB, Bank of Russia); hash, base64, JWT, UUID and JSON utilities. x402 USDC micropayments, no account or API key. Charged only on success.
Output
Returns a JSON object containing three fields: 'header' (the decoded JWT header with algorithm and type), 'payload' (all claims embedded in the token such as sub, exp, iat, and any custom claims), and 'expired' (a boolean indicating whether the token's exp claim is in the past). No signature verification is performed — this is purely a decode/inspection operation.
Example use cases
Debug expired auth token
“I have this JWT from our API response and I need to know if it's expired and what the expiration time is — can you decode it? Here's the token: eyJhbGciOiJSUzI1NiJ9.eyJzdWIiOiJ1c2VyXzQ1NiIsImV4cCI6MTYwMDAwMDAwMH0.abc123”
Inspect OAuth token claims
“We got a Bearer token back from the OAuth server and I need to see what scopes and user ID are in the payload — decode it for me: Bearer eyJhbGciOiJIUzI1NiIsInR5cCI6IkpXVCJ9.eyJzdWIiOiJ1c2VyXzc4OSIsInNjb3BlIjoicmVhZCB3cml0ZSJ9.xyz789”
Identify JWT signing algorithm
“Can you decode this JWT and tell me which algorithm was used to sign it and what fields are in the header? Token: eyJhbGciOiJFUzI1NiIsInR5cCI6IkpXVCIsImtpZCI6ImtleS0xIn0.eyJpc3MiOiJteWFwcCJ9.sig”
Technical details
Endpoint
POSThttps://72-56-90-243.sslip.io/v1/util/jwt-decode?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need to inspect the contents of a JWT without needing signature verification — for debugging, logging, extracting claims, or checking expiry. Prefer this over building a local JWT library when operating in an agent context that needs pay-per-use, stateless token inspection with no API key setup. It accepts Bearer-prefixed tokens directly, simplifying header stripping.
Side effects
- Malformed JWT string (not three dot-separated base64 segments) — returns an error
- Empty or missing token field — returns a validation error
- Token with non-standard or corrupted base64url encoding — may fail to parse payload
- Very long tokens may hit request size limits
