Overview

Decodes a JWT and inspects its claims without needing the signing key. Base64URL-decodes header and payload, parses standard claims (iss, aud, sub, exp, iat, nbf, jti), and reports algorithm, key id (kid), token type (typ), TTL, and clock-validity (is_expired / is_not_yet_valid / is_currently_valid_by_clock). Does NOT verify signatures — for inspection only, never trust output for auth decisions. Use it as a JWT parser, JSON Web Token inspector, Bearer token debugger, OAuth ID-token reader, or Auth0 + Cognito + Firebase token inspector.

How to call it

Requests are paid per call over the x402 protocol. Call the endpoint, receive a 402 Payment Required quote, then repeat the request with the signed payment header. The SDKs do both steps for you.

# 1. Ask for a quote
curl -i -X POST https://api.jarvisclaw.ai/v1/marketplace/api/jwt-decode-254 \
  -H 'Content-Type: application/json' \
  -d '{}'

# 2. Pay it (the SDK signs and retries for you)
curl -X POST https://api.jarvisclaw.ai/v1/marketplace/api/jwt-decode-254 \
  -H 'Content-Type: application/json' \
  -H 'X-PAYMENT: <signed-payload>' \
  -d '{}'
