## 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 saylor-innovations-package-download-trends-0d4b155e
```

Example prompt: Can you pull the download trend stats for the 'axios' npm package — I want to see last day, last week, 30-day totals, the daily series, and how it's changed week over week?

## When to prefer this

Use this endpoint when you need quick, multi-period download statistics for a specific open source package across npm, PyPI, or crates.io — especially when you need both aggregate totals and a daily time series with week-over-week trend in a single call. Prefer this over scraping registry websites or piecing together multiple API calls to individual registries.

## Known failure modes

- Package not found on the specified ecosystem returns an error or empty result
- Invalid or misspelled ecosystem name returns a bad request error
- Very new packages with no download history may return zeros or sparse series data
- Rate limiting or payment failure returns a 402 or 429 error
- Network timeout if the upstream registry API is slow

## How this service works

Package download trend - last day, week and 30 days of downloads, daily series and week-over-week change for any npm, PyPI or crates.io package

## Output

Returns download counts for the last day, last week, and last 30 days, a daily time-series array of download counts, and the week-over-week percentage change for the specified package on the requested ecosystem (npm, PyPI, or crates.io).
