## 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-ratings-summary-a7517a5f
```

Example prompt: Pull the full ratings summary for the podcast with iTunes ID 1200361736 — I want to see the breakdown by platform and locale, the combined roll-up score, and the latest AI-generated narrative of what listeners are saying.

## When to prefer this

Choose this endpoint when you need a one-call consolidated view of a podcast's ratings health — including per-platform breakdowns, locale-level granularity, a combined roll-up, and an AI narrative of listener sentiment — rather than querying multiple platform APIs individually or scraping review pages.

## Known failure modes

- Invalid or unknown podcast ID returns a 404 not found error
- Payment failure or insufficient USDC balance returns a 402 payment required response
- Podcast exists but has no ratings data yet returns empty arrays with null roll-up
- Rate limiting or quota exhaustion returns a 429 too many requests error
- Malformed slug or non-numeric iTunes ID returns a 400 bad request

## How this service works

Summarize a podcast's ratings. Returns the numeric aggregate of a podcast's ratings — one entry per (platform, locale) it has been rated on, a combined cross-source roll-up, and the latest LLM-generated narrative summary of recent review text

## Output

Returns one ratings entry per (platform, locale) pair the podcast has been rated on, a combined cross-source numeric roll-up score, and an LLM-generated narrative summary synthesizing recent review text — all in a single response.
