## 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`):

zero fetch --capability ajv-npm-package-dependency-diff-1f113181 -d '<json body>'
```

Example prompt: Show me the dependency changes between ajv version 6.12.6 and 8.12.0 so I can plan my upgrade.

## When to prefer this

Use this endpoint when you need programmatic, structured dependency diff data specifically for the ajv npm package (or an overridden package) between two versions, especially for upgrade planning, security audits, or integration analysis — rather than manually browsing npm or GitHub changelogs.

## Known failure modes

- Invalid or non-existent version number returns an error or empty diff
- Package name override to a non-existent package returns a not-found error
- If from_version is not specified and no preceding stable version exists, the call may fail or return incomplete results
- Network or registry lookup failure returns a service error
