## 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 particle-pro-podcast-rankings-movers-f87b003d
```

Example prompt: Show me the top 10 podcasts that moved up on the Apple charts in the US compared to 7 days ago — include new debuts and rank climbers.

## When to prefer this

Use this endpoint when you need to track podcast chart momentum — specifically which shows are rising, falling, debuting, or exiting rankings on Apple or Spotify across different countries and categories. Prefer this over a static rankings list when change detection and trend analysis are the goal rather than a snapshot of current positions.

## Known failure modes

- Invalid country code returns an error or empty results
- Unsupported chart_type value returns a validation error
- window_days with no available snapshot returns empty or approximate comparison
- Invalid source/platform enum value causes a 400 error
- No movers found for the given filters returns an empty list
- Rate limiting or payment failure returns a 402 or 429 error

## How this service works

List ranking movers. Returns the chart entries whose rank changed between the live snapshot and the comparison snapshot window_days ago.

## Output

A list of podcast chart entries that experienced rank changes, including each podcast's identifier, previous and current rank positions, change type (up/down/new/exit), and associated metadata such as title and category. Results are scoped to the requested platform, country, chart type, and comparison window.
