## 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 tokensafe-production-up-railway-app-7b42b8d9 -d '<json body>'
```

Example prompt: Can you check if this token is safe to use: 'sk-abc123xyz789abcdef' — I want to know before I deploy it in my app.

## When to prefer this

Use this endpoint when you need a quick, per-call safety check on a token or credential before using it in an application, especially when you want a lightweight pay-per-use validation without committing to a subscription service. Ideal for pre-deployment security checks or runtime credential verification.

## Known failure modes

- Missing or malformed token input returns a 400 error
- Invalid request format causes processing failure
- Payment not provided or insufficient USDC balance blocks the request
- Token too short or unrecognized format may return inconclusive result
- Network timeout on Railway-hosted service under load

## Output

Returns a safety assessment indicating whether the provided token is safe, compromised, or flagged, along with relevant risk or validation details.
