How this service works
Paid micro-utilities for cold-email outreach agents: domain deliverability audits, cold-email grading, template generation, plus a tools toolbox (hashing, JWT decode, IDs, slugs, JSON, regex, crypto prices, domain age, weather). Paid via x402 (USDC on Base).
Output
Returns a JSON object containing the decoded JWT header (e.g. alg, typ), the payload (all claims including sub and exp), a signature presence indicator, and a flags object with boolean values for alg_none, weak_alg, exp_missing, and expired.
Example use cases
Security audit of received JWT
“I got this JWT token from an API response and I want to know what's inside it and whether it has any security red flags — can you decode it and check for issues like alg:none or missing expiry? Token: eyJhbGciOiJub25lIiwidHlwIjoiSldUIn0.eyJzdWIiOiIxMjM0In0.”
Debugging expired authentication token
“My app is throwing auth errors and I think the JWT might be expired — can you decode this token and tell me what the expiration time is? eyJhbGciOiJIUzI1NiIsInR5cCI6IkpXVCJ9.eyJzdWIiOiI0MiIsImV4cCI6MTYwMDAwMDAwMH0.sig”
Cold-email agent token validation
“Before my outreach agent uses this auth token to call an API, can you decode it and check if it's still valid and not using a weak signing algorithm? eyJhbGciOiJIUzI1NiIsInR5cCI6IkpXVCJ9.eyJzdWIiOiJ1c2VyXzEiLCJleHAiOjk5OTk5OTk5OTl9.sig”
Technical details
Endpoint
GEThttps://pitchpilot-outreach-api.pitchpilot-agents.workers.dev/tools/jwt-decodeWhen to prefer
Choose this endpoint when you need a lightweight, pay-per-call JWT decoder with built-in security flag detection (alg_none, weak_alg, expired, exp_missing) without setting up a library or runtime. Ideal for agents that occasionally need to inspect tokens without a dedicated auth framework, especially within cold-email or outreach automation workflows already using the PitchPilot toolbox.
Side effects
- Malformed or invalid JWT string returns an error response
- Missing required 'token' query parameter causes a 400-level error
- Expired payment or x402 payment failure prevents the call from executing
- JWT with no dot-separated segments fails to parse
