## 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-lookup-by-external-platform-id-22b934aa
```

Example prompt: Can you look up the podcast with Spotify show ID '3jEBrMqFSjbBrLqAlhiLLF' on Particle Pro and get me its Particle podcast record?

## When to prefer this

Use this endpoint when you have an external podcast identifier (Apple Podcasts, Spotify, YouTube, or an RSS feed URL) and need to map it to a Particle podcast record for further querying — such as fetching related shows, advertiser data, or political bias metrics. Prefer this over a general search when you already know the exact platform-native ID.

## Known failure modes

- Identifier not found on the specified platform returns empty or null result
- Invalid or unsupported platform slug returns an error
- Exceeding the 100-identifier-per-call limit causes a validation error
- Malformed RSS URL when using platform=rss may fail to match
- Rate limiting or payment failure ($0.01 USDC per call) blocks the request

## How this service works

Look up podcasts by external platform identifier. Resolves one or more external platform identifiers (Apple Podcasts collection IDs, Spotify show IDs, YouTube channel IDs, …) — or RSS feed URLs via platform=rss — to Particle podcasts.

## Output

Returns one or more Particle podcast objects matched to the provided external platform identifiers, including Particle's internal podcast ID and associated metadata for each resolved podcast.
