# Particle: List Publisher Advertising Sponsors

> List the sponsors advertising across a publisher's podcasts, from its publisher slug. Includes inputs, outputs, SDK V2 examples, and Deepline cost.

List the sponsors advertising across a publisher's podcasts, from its publisher slug.

> [!NOTE]
>
> Tool ID: `particle_list_publisher_advertising_sponsors`

## Run this action

Use the TypeScript SDK for one call. Use `ctx.tools.execute(...)` inside a Play for durable calls, scheduled calls, or CSV processing.

```ts theme={"languages":{"custom":["/languages/deepline-prompt.json"]}}
import { Deepline } from 'deepline';

const deepline = await Deepline.connect();
const result = await deepline.tools.execute(
  'particle_list_publisher_advertising_sponsors',
  {
    "id": "id_123"
  },
);

console.log(result.toolResponse.raw);
```

### CLI

```bash theme={"languages":{"custom":["/languages/deepline-prompt.json"]}}
deepline tools execute particle_list_publisher_advertising_sponsors --input '{
  "id": "id_123"
}' --json
```

## Example response

The SDK returns this shape at `result.toolResponse.raw`. The example values illustrate the response.

```json theme={"languages":{"custom":["/languages/deepline-prompt.json"]}}
{
  "data": {
    "data": [
      {
        "ad_count": 123,
        "coverage_share": 123,
        "episode_reach": 123,
        "id": "id_123",
        "name": "Example",
        "podcast_coverage": 123
      }
    ],
    "has_more": true
  }
}
```

Use `deepline describe particle_list_publisher_advertising_sponsors --json` for the latest machine-readable contract.

## Input reference

Returns a paginated list of sponsors active across the publisher's catalog. Each entry includes the bundle-buy signal — podcast\_coverage (distinct podcasts in the catalog where the sponsor appears) and coverage\_share (the same as a 0..1 fraction of the publisher's catalog). Sort by podcast\_coverage and combine with min\_podcast\_coverage to surface network buyers.

| Name | Type | Required | Default | Details |
| - | - | - | - | - |
| `payload.limit` | `integer` | No | `25` | Results per page Format: `int64`. Minimum: 1. Maximum: 100. |
| `payload.cursor` | `string` | No | — | Opaque pagination cursor from previous response |
| `payload.q` | `string` | No | — | Search by name (case-insensitive partial match) Maximum length: 200. |
| `payload.id` | `string` | Yes | — | Podcast publisher slug (e.g., 'iheartpodcasts', 'bbc-radio-4') or ID |
| `payload.sort` | `"ad_count" \| "podcast_coverage" \| "episode_reach"` | No | `"ad_count"` | Sort order. ad\_count ranks by ad volume on the publisher's catalog. podcast\_coverage surfaces network buyers (sponsors hitting many shows). episode\_reach prioritizes broad episode-level exposure. Allowed: `ad_count`, `podcast_coverage`, `episode_reach`. |
| `payload.min_podcast_coverage` | `integer` | No | — | Only return sponsors that appear on at least this many distinct podcasts in the publisher's catalog. Use to filter for bundle/network buyers. Format: `int64`. Minimum: 0. Maximum: 500. |
