## 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`):

Example prompt: Pull the 20 most recent podcast ad placements for Squarespace from Particle Pro, filtering for episodes published since January 1 2024, and show me the episode title, podcast name, and any co-sponsors.

## When to prefer this

Use this endpoint when you need structured, attributed podcast advertising data for a specific company — including episode context, co-sponsor relationships, and time-bound filtering. It is ideal for competitive intelligence, brand tracking, and sponsorship research workflows. Prefer this over generic web search or podcast directory APIs when you need machine-readable, paginated advertising placement data with sponsor attribution.

## Known failure modes

- Unknown company slug or domain returns a 404 or empty result set
- Invalid cursor value causes a pagination error
- Date range filters with malformed ISO 8601 strings return a 400 validation error
- Requesting a nonexistent podcast_id returns an empty placement list
- Rate limiting or payment failure (x402) blocks the request
- Very new or obscure companies may return zero placements
