## 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 npm-package-leak-detector-mcp-f7291fb0 -d '<json body>'
```

Example prompt: Can you scan this npm package data for any leaked secrets, API keys, or hardcoded credentials? Here's the package content: 'const apiKey = "sk-abc123..."; module.exports = apiKey;'

## When to prefer this

Choose this endpoint when you need to programmatically detect leaked secrets or sensitive credentials within npm package content — especially before publishing packages, auditing third-party dependencies, or running automated supply-chain security checks. Prefer this over generic secret-scanning tools when working specifically with npm package data formats.

## Known failure modes

- Empty or malformed 'data' field returns an error or empty result
- Very large package payloads may time out or be rejected
- Obfuscated or minified code may reduce detection accuracy
- False positives may be returned for placeholder or example credential strings
- Non-npm or unrecognized data formats may not be analyzed correctly
