## 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 hermes-profit-engine-app-store-watch-c9e9aaa8
```

Example prompt: Keep an eye on the top productivity apps in the iOS App Store and let me know if any new apps enter the top 10 or if existing rankings shift significantly.

## When to prefer this

Choose this endpoint when you need real-time or near-real-time app store monitoring and competitive intelligence, especially if you want to detect ranking changes, new entrants, or listing updates without scraping the app store yourself. Pairs well with the sibling PR Watch and Citation Check endpoints on the same platform for a broader competitive intelligence workflow.
