Get WeChat Channels User Collections

**Pricing** — billed per successful call; the final charge scales by your plan multiplier. Charged only when the upstream response body `code` is `200`.

<Note>
  Response structure is not yet fully documented — **refer to the actual API response**.

## Example

```bash theme={null}
curl -X POST "https://api.aisa.one/apis/v1/tikhub/wechat_channels/v2/fetch_user_collections" \
  -H "Authorization: Bearer YOUR_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{}'  # see request schema below

      summary: Get WeChat Channels User Collections
      description: >-
        WeChat Channels (v2). Pricing and billing notes describe the upstream
        provider. Use the AIsa price quote for gateway calls.


        ### Purpose

        - Get the "Collections" list on a creator's homepage. Pass each
        collection's `topic_id` to `fetch_collection_videos` to get its videos.

        - ⏱️ 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 `topic_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

        - username: WeChat Channels finder username (`v2_…@finder` format). E.g.
        `v2_060000231003b20faec8c6e4811dc1d4c602ee30b0771bbcf220c67926bb76ab7702ac335a53@finder`
        (People's Daily).

        - raw: Optional, default True. True=raw response; False=simplified
        parsed structure.


        ### Return

        - Collection list


        ### Response structure & JSON Path

        #### `raw=false` (simplified, snake_case):

        - `$.data.username` — finder username

        - `$.data.count` — total collections (e.g. 6)

        - `$.data.collections[]` — collection array, per item (N is the index):
            - `$.data.collections[N].topic_id` — collection ID (numeric, pass to `fetch_collection_videos`, e.g. `14616794565351966924`)
            - `$.data.collections[N].name` — collection name 
            - `$.data.collections[N].desc` — collection description (may be empty string)
            - `$.data.collections[N].cover_url` — collection cover
            - `$.data.collections[N].feed_count` — number of videos in the collection
            - `$.data.collections[N].topic_type` — collection type (e.g. 16, matches `topic_type` of `fetch_collection_videos`)
        #### `raw=true` (full raw response, camelCase):

        - `$.data.collectionCount` → `count`

        - `$.data.collectionInfo[]` → `collections[]`, per item:
            - `$.data.collectionInfo[N].collectionTopicId` → `topic_id` (number; `collectionTopicIdStr` provides a string alias)
            - `$.data.collectionInfo[N].collectionName` → `name`
            - `$.data.collectionInfo[N].collectionDesc` → `desc`
            - `$.data.collectionInfo[N].coverImgUrl` → `cover_url`
            - `$.data.collectionInfo[N].feedCount` → `feed_count`
            - `$.data.collectionInfo[N].collectionTopicType` → `topic_type`
            - Also raw fields like `lastUpdateTime` / `readCount` / `categoryId`
        - `$.data.lastBuffer` — pagination cursor of the collection list
        (usually empty; few collections, no pagination needed)
