# WeChat Channels video comments

Get first-level comments of a video (with IP region / like count); pass comment_id to get second-level replies under that comment. Needs object id. Served by TikHub.

Purpose:
- Get first-level comments of a video (with IP region / like count); pass `comment_id` to get second-level replies under that comment.
- Supports pagination for more comments.
- ⏱️ Due to WeChat server latency, this endpoint responds slowly; please set your client request timeout to 30 seconds — a timeout that is too small may result in being billed without receiving the response.
- ⚠️ Large-integer ID precision: IDs such as `comment_id` in the response are 64-bit big integers beyond JavaScript's safe-integer range (2^53-1). Always receive / pass such IDs as **strings** (parse JSON with json-bigint or read them as text), never through JS `Number`. Swagger UI rounds the trailing digits of huge integers in its docs view — this is expected and does not affect the actual data returned by the API.
Parameters:
- object_id: Video objectId (numeric), e.g. `14941130915890399732`. From the video `id` of `fetch_user_videos` / `fetch_video_detail`.
- last_buffer: Optional pagination cursor (base64). **Leave empty for the first page**; when `down_continue` is truthy, pass the previous page's `last_buffer`.
- comment_id: Optional. To expand the replies of a comment, pass its `comment_id` (numeric); leave empty for the first-level page.
- raw: Optional, default True. True=raw response; False=simplified parsed structure.
Return:
- Comment list with pagination cursor

Response structure & JSON Path:
`raw=false` (simplified):
- Top level: `$.data.object_id` (echo) / `$.data.comment_id` (echo when expanding replies, otherwise null) / `$.data.count` (comments on this page) / `$.data.d

## Published example

This is the provider tool’s published example. Replace example values with the user’s requested inputs, respecting the schema; do not execute an example merely to test a connection.


```json
{

  "input": {
    "object_id": "14941130915890399732",

## Execute and retrieve

Inspect again before execution, explain the price and obtain the required authority. Use MCP run_tool or POST /v1/run with this tool ID, valid input and an idempotency key. Save the returned run ID and follow the actual state. If Agentik answers that the tool is temporarily unavailable, do not retry it blindly; use discovery to propose an alternative.

A partial or uncertain result can still have consumed provider resources. Consult [billing](/docs/billing.md), [idempotency](/docs/idempotency.md) and [asynchronous results](/docs/async.md).
