# Twitter Video Caption
> Get Twitter video caption.
**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 endpoint allows you to generate visual captions for a Twitter video.
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.
**Pricing:** Base fee ($0.01/video) + Input tokens ($0.45/1M) + Output tokens ($3.75/1M) + Duration ($0.0001/sec)
This is an **asynchronous** endpoint. It returns a `task_id` immediately. You must configure a [Webhook](/visual-intelligence/getting-started/webhooks) to receive the processing results.
If no webhook is configured on the account, the call is **rejected at submit time** with `HTTP 400`:
```json theme={null}
{"code": 400, "msg": "An async request requires at least one webhook.", "data": null}
```
### 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}"
}
def twitter_video_caption(video_url: str):
url = f"{BASE_URL}/twitter/video/mai/transcript"
data = {"video_url": video_url}
resp = requests.post(url, headers=HEADERS, json=data)
return resp.json()
# Usage example
result = twitter_video_caption("https://x.com/NBCOlympics/status/1989901761650323606")
print(result)
```
### Response
Returns the caption task information.

The women continue to smile and laugh, one of them patting his shoulder."
