## 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-get-podcast-chart-slot-history-88d429b2
```

Example prompt: Pull the Apple top_podcasts chart history for the US, limited to 20 results per page, from January 1 2025 to March 31 2025 — I want to see how rankings changed over that period.

## When to prefer this

Use this endpoint when you need historical chart ranking data for podcasts on Apple or Spotify, especially when you need to analyze trends over time, track a specific podcast's chart trajectory, or compare rankings across date ranges. Prefer this over live/current chart endpoints when retrospective analysis is the goal.

## Known failure modes

- Invalid country code returns an error or empty results
- Unsupported chart_type value rejected (only 'top_podcasts' allowed)
- Invalid source platform (only 'apple' or 'spotify' accepted)
- Malformed ISO 8601 date strings for since/until return validation errors
- Invalid pagination cursor returns an error
- No data available for specified filters returns empty result set
- Payment failure (x402) blocks access to the endpoint
