## 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-advertising-sponsor-ad26102b
```

Example prompt: Pull up the Particle Pro sponsor profile for squarespace.com and show me their podcast ad activity from 2024-01-01 to 2024-12-31.

## When to prefer this

Use this endpoint when you need detailed advertising activity metrics for a specific known sponsor, identified by company domain, slug, or ID. Prefer this over list endpoints when you already know which company you're researching and want focused metrics rather than ranked or paginated results. Ideal for brand intelligence, competitive ad-spend research, or validating whether a specific company is actively advertising on podcasts.

## Known failure modes

- Sponsor ID not found — 404 if the provided ID, domain, or slug doesn't match any sponsor
- Multiple alias match resolved to most-recently-active sponsor — may not be the intended sponsor
- Invalid date format for since/until — 400 if not valid ISO 8601
- Empty metrics if no ads fall within the specified date range
- Company exists but has no sponsorship history — returns sponsor with zero activity metrics

## How this service works

Get a sponsor. Returns a single advertising sponsor with activity metrics.

## Output

Returns a single sponsor object including the sponsor's identity (linked company, aliases), and advertising activity metrics such as ad counts and episode coverage, optionally scoped to a date range defined by since/until parameters.
