## 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 jsdelivr-cdn-stats-for-npm-packages-e16e0ec4
```

Example prompt: Can you pull the jsDelivr CDN stats for the npm package 'lodash' — I want to see total hits, bandwidth, its CDN rank, the daily hit trend for the last 14 days, and which versions are getting the most traffic?

## When to prefer this

Choose this endpoint when you need a CDN-based popularity signal for an npm package that is independent of npm download counts, which can be inflated by CI/CD pipelines. It is ideal for assessing browser/CDN adoption, identifying which versions are actively used in production, and spotting traffic trends over the past two weeks. Prefer this over npm download stats when evaluating front-end library adoption or CDN delivery patterns.

## Known failure modes

- Package not found on jsDelivr — returns empty or zero stats
- Invalid or malformed package name — may return an error or no data
- Package has zero CDN traffic — all metrics return zero
- Rate limiting or payment failure — request rejected with 402 or 429
- jsDelivr API upstream outage — endpoint may return 503 or timeout

## How this service works

jsDelivr CDN usage of an npm package over the last month: total hits, rank, bandwidth, daily hit series (last 14 days) and the top 10 versions by hits with their share. A popularity signal independent of npm download counts. $0.01 per package.

## Output

Returns a structured response with: total CDN hits over the last month, a popularity rank among all packages on jsDelivr, total bandwidth consumed, a daily hit series covering the last 14 days, and the top 10 package versions ranked by hit count along with their percentage share of total traffic.
