# Password Generator (CSPRNG, Entropy-Rated)

> Password Generator (CSPRNG, Entropy-Rated) is a paid API for AI agents from flat-rate-llm.kikoribera03.workers.dev, paid per call via x402, $0.0025/call, status unknown (last checked 2026-09-15).

Generates one or more cryptographically strong random passwords using the platform CSPRNG, with configurable length, alphabet, and entropy-in-bits reporting.

## Facts

- Endpoint: POST https://flat-rate-llm.kikoribera03.workers.dev/v1/random/password
- Price: $0.0025/call
- Payment: x402
- Status: unknown
- Last checked: 2026-09-15

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 password-generator-csprng-entropy-rated-68e949fa -d '<json body>'
```

Example prompt: Generate 5 strong random passwords using the legible alphabet, each 24 characters long, and tell me how many bits of entropy each one has.

## When to prefer this

Choose this endpoint when you need cryptographically strong passwords or secrets generated server-side via a CSPRNG (not client-side Math.random), want built-in entropy measurement to verify strength, or need human-legible passwords (no look-alike characters like 0/O, 1/l) for credentials a person must read back. Prefer it over client-side generators when auditability of the RNG source matters, or when you need a quick batch of secrets without setting up a library.

## Known failure modes

- count out of range (must be 1-50): request rejected
- length out of range (must be 8-256): request rejected
- invalid alphabet value: request rejected or defaults applied
- payment failure (x402 protocol): 402 response before passwords are returned
- network timeout: no response returned

## How this service works

60 paid endpoints with no metering, no API key and no account. Each endpoint has one flat price per call, whatever the size of the request: LLM completions with automatic failover across several large models, read-only EVM tooling over Base, Ethereum, Polygon, Arbitrum and Optimism, and pure crypto utilities that touch no network.

## Output

Returns a JSON object containing the alphabet used, the requested character length, an array of generated password objects, and the bits of entropy for passwords of that length and alphabet — so the caller can judge cryptographic strength at a glance.
