# Agent Dev Tools – Secure Password Generator

> Agent Dev Tools – Secure Password Generator is a paid API for AI agents from agent-dev-tools.frcompanycheck.workers.dev, paid per call via x402, $0.001/call, status unknown (last checked 2026-10-12).

Generates one or more cryptographically random passwords with configurable length, character set, and symbol inclusion, returning each password along with its entropy in bits.

## 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 agent-dev-tools-secure-password-generator-4e9c07e9
```

Example prompt: Generate 3 secure random passwords, each 24 characters long, using the full character set including symbols — I need them for new service accounts.

## When to prefer this

Choose this endpoint when you need instant, cryptographically secure password generation without setting up an account or API key, and you want transparent per-call USDC micropayment pricing. Ideal for AI agents that need to provision credentials on-the-fly. Prefer over rolling your own PRNG or using a heavyweight secrets-management API for simple password generation tasks.

## Known failure modes

- Invalid length parameter (outside 8–128 range) returns an error and is not charged
- Invalid count parameter (outside 1–20 range) returns an error and is not charged
- Invalid charset value returns an error and is not charged
- Payment failure via x402 (insufficient USDC balance) blocks the call
- Network timeout on the Cloudflare Worker edge

## How this service works

Fast deterministic developer utilities for AI agents, paid per call in USDC via x402 (no account, no API key): UUID v4/v7, secure random numbers, dice, MD5/SHA/HMAC hashing, base64/hex/URL/HTML encoding, JSON validation/formatting, QR code SVG, password generation, JWT decoding and text statistics. Pure computation, nothing stored. Errors are never charged.

## Output

A JSON object containing the requested passwords as an array of strings, the configured length, and the entropy in bits per password (e.g. {"length":20,"passwords":["q8#Vt…"],"entropy_bits":131}). No data is stored server-side.
