## When to use this

Use it to read a comment's thread. Get `comment_id` from a comment's `cid` in video comments. `reply_to_reply_id` shows which reply a reply answers.

**Pagination.** 50 replies per page. Pass the response's `cursor` back as `cursor` (with the same `url` and `comment_id`); it's null at the end.

## Parameters

All parameters go in the query string.

| Name | Type | Required | Default | Allowed values | Description | Example |
| --- | --- | --- | --- | --- | --- | --- |
| `url` | string | yes |  |  | The video's URL, e.g. `https://www.tiktok.com/@hubspot/video/7671325437229845774`. Photo post URLs and bare video ids work too. | `https://www.tiktok.com/@scout2015/video/6718335390845095173` |
| `comment_id` | string | yes |  |  | The comment's `cid`, from video comments. | `6718335906996502534` |
| `cursor` | string | no |  |  | The `cursor` from the previous response, to get the next page. |  |

## Response fields

Every field of a successful response. `[]` marks a list: `a[].b` is the `b` of each item in `a`. **nullable** fields can be `null`; **optional** fields can be missing.

| Field | Type | Description |
| --- | --- | --- |
| `success` | `true` | Always true here; errors have `success: false`. |
| `credits_remaining` | `number` | Your balance after this call. On anonymous playground calls: free tries left today. |

## Pagination

Pass the response's `cursor` back as `cursor`, with the other parameters unchanged, for the next page. It's `null` on the last page. Each page costs 1 credit.

The first five pages, in JavaScript:

```js
let cursor = null;
for (let page = 1; page <= 5; page++) {
  const params = new URLSearchParams({ url: "https://www.tiktok.com/@scout2015/video/6718335390845095173", comment_id: "6718335906996502534" });
  if (cursor) params.set("cursor", cursor);
  const res = await fetch(`https://api.lurkapi.com/v1/tiktok/video/comment/replies?${params}`, {
    headers: { "x-api-key": process.env.LURKAPI_KEY },
  });
  const data = await res.json();
  if (!data.success) throw new Error(`${data.code}: ${data.error}`);
  console.log(data.comments);
  cursor = data.cursor;
  if (!cursor) break; // last page
}
```

## Caching and freshness

Responses are cached for up to 5 minutes, so a repeat call within that window can return the same data. It still costs 1 credit.

## Errors

Errors return `{ success: false, error, code, docs }` with the HTTP status below. Validation errors, `401`/`402`/`429` rejections and `5xx` failures are free; `not_found` is charged ([how charging works](https://lurkapi.com/docs.md#credits)). [All error codes](https://lurkapi.com/docs.md#errors).

| Status | Code | Meaning |
| --- | --- | --- |
| 401 | `missing_api_key` | No API key. Send it in the `x-api-key` header. |
| 401 | `invalid_api_key` | The key is unknown or was revoked. |
| 402 | `insufficient_credits` | Not enough credits for this call. Buy a pack or wait for tomorrow's top-up. |
| 404 | `not_found` | The endpoint, or the thing you asked for (ad, post, subreddit), doesn't exist. Charged when the platform was checked. |
| 405 | `method_not_allowed` | Endpoints take GET with query params. |
| 429 | `rate_limited` | Too many calls at once. Wait for the `retry-after` seconds, then retry. |
| 500 | `internal_error` | Something broke on our side. Retry; 5xx errors are free. |
| 502 | `upstream_error` | The platform didn't give a usable answer. Retry; 5xx errors are free. |
| 503 | `upstream_busy` | All our connections to the platform are busy. Retry in a few seconds; 5xx errors are free. |
| 504 | `upstream_timeout` | The platform took over 30 seconds to answer. Retry; timeouts are free. |

## Use it in Claude

Once LurkAPI is [connected to Claude](https://lurkapi.com/docs.md#claude), this endpoint is the `tiktok_comment_replies` tool. Ask in plain English, for example:

Ask Claude:

```text
Use LurkAPI's tiktok_comment_replies with url "https://www.tiktok.com/@scout2015/video/6718335390845095173", comment_id "6718335906996502534" and summarize what you find.
```

Claude calls `tiktok_comment_replies` with arguments like these, and each call costs 1 credit:

Tool arguments:

```json
{
  "url": "https://www.tiktok.com/@scout2015/video/6718335390845095173",
  "comment_id": "6718335906996502534"
}
```

Tool results skip nulls and empty lists to save tokens.
