## 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-ad-segments-for-sponsor-58b74a4f
```

Example prompt: Show me all the individual podcast ad segments attributed to HubSpot, scoped to the 'My First Million' podcast, for episodes published since January 1, 2024.

## When to prefer this

Use this endpoint when you need granular, per-segment ad placement data for a specific sponsor rather than aggregate advertising intelligence. Prefer this over the company advertising profile endpoint when you need a chronological feed of individual ad segments with date-range filtering or podcast-scoped results. Best for tracking campaign recency, auditing ad frequency, or building historical timelines of a brand's podcast presence.

## Known failure modes

- Invalid or unknown sponsor ID returns a 404 not found error
- Malformed ISO 8601 date in `since` or `until` causes a 400 bad request
- Invalid pagination cursor causes a 400 or empty result set
- Unknown podcast_id causes empty results or 404
- Exceeding rate limits or payment failure (x402) results in 402 Payment Required
- No segments found for sponsor returns empty list with no error
