# Particle: List Sponsor Publishers

> List the podcast publishers a sponsor advertises with, from a sponsor ID (from particle_list_sponsors). Includes SDK V2 examples, schemas, and cost.

List the podcast publishers a sponsor advertises with, from a sponsor ID (from particle\_list\_sponsors).

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

## 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_sponsor_publishers',
  {
    "id": "id_123"
  },
);

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

### CLI

```bash theme={"languages":{"custom":["/languages/deepline-prompt.json"]}}
deepline tools execute particle_list_sponsor_publishers --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,
        "podcast_coverage": 123,
        "publisher": {
          "id": "id_123",
          "name": "Example"
        },
        "publisher_podcast_count": 123
      }
    ],
    "has_more": true
  }
}
```

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

## Input reference

Returns the podcast publishers a sponsor advertises across, ordered by podcast coverage (the count of distinct publisher podcasts where the sponsor appears). Surfaces the bundle-buy signature: a sponsor showing 60–100% coverage on multiple publishers is doing network buys, not per-show buys.

| 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.id` | `string` | Yes | — | Sponsor ID, company ID, company domain, or company slug. When the value resolves to a company (not a specific sponsor), the response aggregates across every sponsor linked to that company — the canonical 'where does this advertiser buy?' view. When it resolves to a sponsor ID, the response is scoped to that single deduped sponsor. |
