supadata-langchain 0.1.0

Supadata document loader integration for LangChain (Python)

supadata-langchain

Supadata document loader integration for LangChain (Python).

This package provides a SupadataLoader that calls Supadata’s video/post scraping endpoints only:

• transcript — fetch a transcript for a social media video/post URL
• metadata — fetch structured metadata for a social media video/post URL

Supadata supports social media video/post URLs (YouTube, TikTok, Instagram, Facebook, and X/Twitter).

Usage

import os
from supadata_langchain import SupadataLoader

os.environ["SUPADATA_API_KEY"] = "YOUR_API_KEY"

docs = loader.load(
    {
        "url": "https://www.youtube.com/watch?v=dQw4w9WgXcQ",
        "operation": "transcript",
        "lang": "en",
        "text": True,
