| --------- | ---------------------------------------------------------------------- | -------- |
| `id`      | The ID of the event whose replies are requested in hexadecimal format. | Yes      |
| `depth`   | The maximum depth of replies to fetch.                                 | No       |
| `limit`   | The maximum number of events to return.                                | No       |

## Response Schema

The response is a JSON object with the following structure:

```json
{
  "id": "root_event_id",
  "events": [
    {
      "id": "event_id",
      "pubkey": "author_pubkey",
      "created_at": 1234567890,
      "kind": 1,
      "tags": [],
      "content": "Event content",
      "sig": "event_signature"
    }
  ],
  "profiles": {
    "author_pubkey": {
      "id": "profile_event_id",
      "pubkey": "author_pubkey",
      "created_at": 1234567890,
      "kind": 0,
      "tags": [],
      "content": "Profile content",
      "sig": "profile_signature"
    }
  },
  "depth": 3
}
```

* `id`: The ID of the event whose comment thread is being retrieved.
* `events`: An array of events in the thread, including the original event.
* `profiles`: A map of author profiles, keyed by pubkey.
* `depth`: The actual depth reached in the thread.

## Example Call

```bash
curl -X GET "https://huddlers-ovduv.ondigitalocean.app/thread?id=5c3e529bb75f165d822b468114e3bc928288ae5679e38849452e0389124a333b&depth=3&limit=5"
```

## Notes

* If `depth` is not provided, it defaults to 2.
* Once the server collects as many events as are allowed by the `limit` constraint, it returns that set even though it may not have reached the maximum allowed `depth`. Similarly, once all replies up to the specified `depth` have been collected, the set is returned even if the `limit` has not been reached.

## Error Responses

* **400 Bad Request**: If the root event ID is missing or invalid.
* **404 Not Found**: If the root event cannot be found.
* **500 Internal Server Error**: If there's an issue processing the request.
