## 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-advertising-recommendations-for-a-company-3370909c
```

Example prompt: Can you pull up the podcast advertising prospects for Squarespace — I want to see the shows they don't currently advertise on, ranked by how related they are to their existing ad placements, in English only, and show me which of their current shows led to each recommendation?

## When to prefer this

Use this endpoint when you need a buy-side prospect list — showing where a brand should advertise next based on its existing podcast ad footprint. Prefer it over the general 'related podcasts' endpoint when the use case is specifically about a company's advertising gap analysis rather than podcast-to-podcast similarity. It is ideal for media planners, ad sales teams, and brand strategists who need actionable, company-specific recommendations rather than generic podcast discovery.

## Known failure modes

- Unknown company identifier returns 404 or empty result
- Company with no existing ad placements returns empty recommendations (nothing to base similarity on)
- Very restrictive min_score or language filter returns zero results within the 200-recommendation cap
- Invalid cursor causes pagination error
- Rate limit or payment failure (x402) blocks the request

## How this service works

List podcasts a company could advertise on next. Returns shows the company does NOT advertise on, ranked by how related they are to the shows it DOES — the buy-side prospect list.

## Output

A ranked list of podcasts the company does not yet advertise on, each with a relevance/calibration score (and optional band/strength tier), an opaque pagination cursor for subsequent pages, and — if include=via is requested — the company's own current ad shows that semantically drove each recommendation.
