## 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 x402-toolbox-npm-downloads-lookup-f4ddc2cb
```

Example prompt: How many downloads does the 'axios' npm package have? Pay the micropayment and get me the stats.

## When to prefer this

Choose this endpoint when you need npm download statistics without setting up an API key or account — the x402 micropayment ($0.001 USDC) is the only credential required. Ideal for AI agents operating autonomously in crypto-native environments where per-call billing via Base/USDC is preferred over subscription API keys.

## Known failure modes

- Missing or invalid package name returns an error or empty result
- Payment failure via x402 prevents the call from completing
- Package not found on npm registry returns a 404-style error
- Malformed schema parameter may result in unexpected output or rejection
