## 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 steamspy-app-details-27e83600 -d '<json body>'
```

## When to prefer this

Use this endpoint when you need quick ownership estimates, review counts, or concurrent player data for a specific Steam game identified by its numeric app ID. Prefer this over scraping Steam directly when aggregate player statistics are needed without authentication.

## Known failure modes

- Invalid or non-existent app ID returns empty or error JSON
- Private/delisted games may return null or zero values
- SteamSpy rate limits or data staleness may affect accuracy
- Missing appid parameter causes a bad request response
