## 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 whatchuneed-npm-package-lookup-b341f211 -d '<json body>'
```

Example prompt: Can you look up the npm package 'lodash' and tell me its latest version, description, and main dependencies?

## When to prefer this

Use this endpoint when an AI agent needs to quickly fetch npm package information without setting up direct npm registry API access, especially in pay-per-call agentic workflows where occasional lookups don't justify a full integration. Useful for dependency research, license checks, or version verification tasks.

## Known failure modes

- Package name not found in npm registry returns an error result
- Misspelled or scoped package names (e.g. missing @scope/ prefix) may return no results
- Private or unpublished packages are not accessible
- Network or upstream npm registry errors may cause failures
