# YouTube Video Comment Reply
> Get the reply list for YouTube video comments.
**Product**: Visual Intelligence — Social Media Scraping
**Use case**: Fetch video metadata, transcripts, captions, and comments from YouTube, Instagram, TikTok, and Twitter/X
**Host**: `https://mavi-backend.memories.ai/serve/api/v2`
**Auth**: `Authorization: sk-mavi-...` (no `Bearer` prefix)
This API is used to get the reply list for YouTube video comments with pagination support.
Channel routing guide: see [Social Media Scraping Overview](/visual-intelligence/social-media-scraping-overview). Endpoints with a `channel` request field let you choose `apify`, `rapid`, or `memories.ai`; endpoints without this field use managed routing.
Each API call costs **\$0.01 USD**.
### Channel Options
If your request supports a `channel` option, use it to control how scraper data is sourced:
| Channel | What it means | Typical trade-off |
| ------------- | ------------------------------------------------------------------------------------------------ | ----------------------------------------------------------------------- |
| `apify` | Uses [Apify](https://apify.com/), a dedicated web scraping platform with broad content coverage. | Most stable and most complete results, but usually more expensive. |
| `rapid` | Uses [RapidAPI](https://rapidapi.com/), a lower-cost aggregation platform. | Lower cost, but less stable and often narrower coverage. |
| `memories.ai` | Managed routing by Memories.ai. | Automatically selects the best price/performance path for your request. |
Recommendation: Start with `memories.ai` unless you need to force a specific provider.
* The maximum value for pagination parameter `page_size` is **100**
* `next_page_token` should be **null** for the first request, use the `next_page_token` returned from the previous response for subsequent requests
* When `next_page_token` in the response is `null`, it indicates all replies have been retrieved
### Code Example
```python Python theme={null}
import requests
BASE_URL = "https://mavi-backend.memories.ai/serve/api/v2"
API_KEY = "sk-mavi-..."
HEADERS = {
"Authorization": f"{API_KEY}",
"Content-Type": "application/json"
}
def youtube_video_comment_reply(comment_id: str):
url = f"{BASE_URL}/youtube/video/comment/reply"
page_size = 100
next_page_token = None
all_replies = []
while True:
data = {"comment_id": comment_id, "page_size": page_size, "next_page_token": next_page_token}
resp = requests.post(url, json=data, headers=HEADERS).json()
replies = resp.get("items", [])
all_replies.extend(replies)
next_page_token = resp.get("next_page_token")
if not next_page_token:
break
return all_replies
# Usage example
replies = youtube_video_comment_reply("comment_id")
print(replies)
```

);
return response.data;
