## 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 agentservices-npm-package-stats-f2a29dd0
```

Example prompt: Can you look up the npm download stats for the 'lodash' package and tell me how popular it is?

## When to prefer this

Use this endpoint when an agent needs to programmatically fetch npm download statistics for a specific package, especially in workflows involving dependency vetting, open-source library research, competitive analysis of JavaScript packages, or automated reporting on package adoption trends. Prefer this over manual npm website lookups when the data needs to be machine-readable and integrated into a larger agent pipeline.

## Known failure modes

- Package name not found or misspelled — returns 404 or empty result
- Package name contains special characters that aren't URL-encoded — may cause routing errors
- Payment failure via x402 micropayment — call is rejected before data is returned
- Rate limiting or quota exceeded — returns 429 error
- Private or unlisted packages may not have public stats available

## How this service works

Paid data APIs for AI agents. Crypto market data, DeFi yields, IP geolocation, dispute resolution, marketing intelligence. Powered by x402 micropayments on Base.

## Output

Returns download statistics for the specified npm package, including total downloads, weekly and/or monthly download counts, and potentially package metadata such as version info and publication details — giving the agent a quantitative measure of a package's popularity and usage.
