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 safe-upgrade-decision-api-license-check-9e9e96ec -d '<json body>'
```

Example prompt: Check the licenses for lodash, axios, and express in my project — flag any that might cause compliance issues before I upgrade them.

## When to prefer this

Use this endpoint when a coding agent needs to validate npm package license compliance before recommending or executing a dependency upgrade, especially in commercial or open-source projects where license compatibility matters. It's purpose-built for npm ecosystems and returns structured pass/fail evidence suitable for automated CI/CD gates or agent-driven upgrade workflows.

## Known failure modes

- Empty or missing 'packages' array and 'dependencies' object returns a validation error
- Unknown or unpublished package names may not resolve license data
- Payment failure via x402 protocol results in 402 response before processing
- Malformed version strings in the dependencies map may cause lookup failures
- Service may return incomplete data for very new or scoped private packages

## How this service works

Evidence-backed npm package upgrade decisions for coding agents.

## Output

A JSON object containing a summary with a boolean 'passed' field, the total number of packages checked, and the count of flagged packages. Flagged packages are those with licenses that may pose compliance risks.
