## 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 nuget-package-search-e68f823a -d '<json body>'
```

Example prompt: Can you search NuGet for .NET logging packages and show me the top results along with their download counts? I'm looking for something like 'Serilog' or similar.

## When to prefer this

Use this endpoint when an agent needs to search the NuGet package gallery for .NET/C# libraries, retrieve package metadata, or compare packages by popularity via download counts. Prefer this over manual web scraping of nuget.org or general web search when structured, machine-readable package data is needed.

## Known failure modes

- Empty or missing query parameter returns no results or an error
- Query with no matching packages returns an empty result set
- NuGet gallery API unavailable causes upstream failure
- Malformed query may return unexpected results
- Rate limiting or payment failure returns 402 or similar error

## How this service works

Search the NuGet gallery for .NET packages with download counts (param q = query). Query: ?q= Returns JSON.

## Output

A JSON array or object containing NuGet package search results, including package names, descriptions, and download counts for packages matching the query string.
