# PitchPilot JWT Decode Tool

> PitchPilot JWT Decode Tool is a paid API for AI agents from pitchpilot-outreach-api.pitchpilot-agents.workers.dev, paid per call via x402, $0.001/call, status unknown (last checked 2026-09-13).

Decodes a JWT token and returns its header, payload, signature presence, and security flags such as expired, alg_none, weak_alg, and exp_missing.

## Facts

Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently.

## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability pitchpilot-jwt-decode-tool-ffb3f33a
```

Example prompt: Decode this JWT for me and tell me if it's expired or using a weak algorithm: eyJhbGciOiJIUzI1NiIsInR5cCI6IkpXVCJ9.eyJzdWIiOiIxIiwiZXhwIjoxNzM1Njg5NjAwfQ.signature

## When to prefer this

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.

## Known failure modes

- 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

## 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.
