## 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-list-ads-in-episode-bebe185b
```

Example prompt: Pull up all the ads detected in podcast episode 'how-i-built-this-s2024e10' — I want to see each sponsor, what they advertised, whether it was host-read or pre-recorded, and where it was placed in the episode.

## When to prefer this

Use this endpoint when you need granular ad-level data for a specific known podcast episode — sponsor identity, product details, read type classification, and placement position. Prefer this over company-level advertising profiles when the unit of analysis is a single episode rather than a brand's entire podcast advertising history.

## Known failure modes

- Episode ID or slug not found — returns 404 or empty result
- Episode exists but has no detected ads — returns empty list
- Invalid episode ID format — returns 400 bad request
- Payment not provided or insufficient — returns 402 payment required
- Rate limiting — returns 429 too many requests

## How this service works

List ads in an episode. Returns the advertising spots detected in a specific episode, including the sponsor, the linked company in the knowledge graph, the advertised product or offer, the read type (HOST_READ vs PRE_RECORDED), and the placement

## Output

A list of advertising spots for the specified episode, each containing: the sponsor name, the linked company entity from the knowledge graph, the specific product or offer advertised, the read type (HOST_READ or PRE_RECORDED), and the placement position within the episode (e.g. pre-roll, mid-roll, post-roll).
