## 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 coco-password-strength-checker-3c0a132c
```

Example prompt: Can you check how strong the password 'Tr0ub4dor&3' is and give me a score out of 4?

## When to prefer this

Use this endpoint when you need a lightweight, pay-per-call password strength score without setting up a local library. It is ideal for agents automating account creation flows, validating user-supplied passwords, or enforcing password policies at low cost ($0.001 per call).

## Known failure modes

- Missing `pw` query parameter may return an error or a zero/null score
- Extremely long passwords may be truncated or rejected
- Non-string input types will fail schema validation
- Network or server errors may return non-JSON responses

## Output

Returns a JSON object with a single field `score_0_4`, a number between 0 and 4 indicating password strength: 0 = very weak, 4 = very strong.
