## 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 clonecho-npm-package-search-3cf2d3eb -d '<json body>'
```

Example prompt: Search npm for packages matching 'react' and show me their monthly and weekly download counts along with how many packages depend on them, so I can figure out which ones are most widely adopted.

## When to prefer this

Use this endpoint when you need to discover npm packages by keyword and want adoption signals (downloads, dependents) alongside search results — ideal for comparing library popularity or vetting third-party package choices without manually visiting npmjs.com.

## Known failure modes

- Missing or empty ?q= parameter returns error or empty results
- Very broad or generic search terms may return too many low-signal results
- npm registry API unavailability causes 502/503 responses
- Rate limiting may occur if called in rapid succession
- Newly published packages may not yet appear in search index

## How this service works

npm packages matching a term (?q=react) with monthly/weekly downloads and dependent counts — discovery + adoption. Returns JSON.

## Output

A JSON array of npm packages matching the search query, each with package name, description, monthly downloads, weekly downloads, and dependent package count — useful for gauging adoption and community traction.
