JWT Decoder — Inspect Claims, Expiry & Algorithm

axel-belfort/jwt-decoder

JWT token decoder API for AI agents. Decode and inspect JSON Web Tokens without verification: extract header (algorithm, type), payload (claims, issuer, audience), expiry timestamp, and signature info. Tools: security_decode_jwt. Use this for debugging authentication flows, inspecting token claims, or verifying token structure. IMPORTANT: This decodes without verifying — for security validation, verify signatures server-side. Returns: {header, payload, claims, expiresAt, algorithm}. No API key required — x402 micropayment $0.001/call on Base L2.
