## When to use this

Use it to size up a sound before you build content on it: `videoCount` is how many posts use it. `original: true` means a creator's original sound rather than a released track, and `is_commerce_music` is TikTok's flag for sounds cleared for commercial use (the ones business accounts can pick). Get the id from any video's `music.id`, or pass the sound's tiktok.com/music/… URL.

Unknown and removed sounds return 404 `not_found`.

## Parameters

All parameters go in the query string.

| Name | Type | Required | Default | Allowed values | Description | Example |
| --- | --- | --- | --- | --- | --- | --- |
| `clipId` | string | yes |  |  | The sound's id, e.g. `7433619007506761744`, or its URL (`https://www.tiktok.com/music/…-<id>`). Every video carries it as `music.id`. | `7433619007506761744` |

## Example request

## Caching and freshness

Responses are cached for up to 1 hour, 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).

## Use it in Claude

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

Ask Claude:

```text
Use LurkAPI's tiktok_song with clipId "7433619007506761744" and summarize what you find.
```

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

Tool arguments:

```json
{
  "clipId": "7433619007506761744"
}
```

Tool results skip nulls and empty lists to save tokens.
