# List Comments

- Capability ID: `reddit.comments.list`
- Cost: 1 credit per request
- Maximum runtime: 30 seconds
- Execute endpoint: `POST https://data.upscrape.com/execute`

## Request

Use the exact public capability ID in the shared execute envelope.

  -H "Authorization: Bearer YOUR_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{"input":{"limit":25,"subreddits":"SaaS"},"capability":"reddit.comments.list"}'
```

## Input

| Field | Type | Required | Description |
| --- | --- | --- | --- |

| `limit` | `integer` | No | Page size, 1-100 (default 50). |
| `subreddits` | `string` | Yes | Comma-separated subreddit names (no leading r/), or the literal "all" for all of Reddit. |

```

## Response

Successful output is returned in `results[0].data`. Raw platform output is intentionally open-ended and may evolve with the upstream source.

No committed sample output is available for this capability.


## Execution behavior

A `200` response completed inline. A `202` response was queued; poll `GET /jobs/{id}` until the job reaches `completed` or `failed`. Use an `Idempotency-Key` when retrying must not create a duplicate logical job.

See [jobs and results](https://docs.upscrape.com/docs/api/jobs), [errors and retries](https://docs.upscrape.com/docs/api/errors), and [idempotency](https://docs.upscrape.com/docs/api/idempotency).
