## 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 undici-npm-dependency-diff-856950fc -d '<json body>'
```

Example prompt: What dependencies changed between undici 5.28.0 and 6.0.0? I'm planning an upgrade and need to know what was added, removed, or updated.

## When to prefer this

Use this endpoint when you specifically need to compare dependency trees between two releases of the undici npm package (or a compatible override package) for upgrade planning, security auditing, or automated dependency review workflows. Prefer it over generic npm CLI tooling when you need programmatic, structured diff results payable via x402 without setting up local tooling.

## Known failure modes

- Invalid or non-existent version numbers return an error or empty diff
- Package name override to a non-existent package returns not-found error
- Network or npm registry unavailability causes timeout or failure
- Specifying the same version for both from_version and version yields an empty diff
