## 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 rotary-agency-nuget-data-api-f52a29aa
```

Example prompt: Can you look up the NuGet package metadata for 'Newtonsoft.Json' and tell me its latest version, download count, and dependencies?

## When to prefer this

Choose this endpoint when you need quick, structured NuGet package metadata without setting up a direct NuGet API integration; ideal for agents that need .NET package info on demand at very low cost ($0.002/call) without managing authentication or proxy infrastructure.

## Known failure modes

- Package not found returns an empty or error JSON response
- Invalid package name returns 400-level error
- Payment not fulfilled via x402 results in 402 Payment Required
- Rate limiting may apply if payment is not correctly processed
- NuGet upstream unavailability may cause timeouts or stale data
