This page covers how to use Apify within LangChain.
Apify is a cloud platform for web scraping and data extraction, which provides an ecosystem of more than a thousand ready-made apps called Actors for various scraping, crawling, and extraction use cases.
This integration enables you run Actors on the Apify platform and load their results into LangChain to feed your vector indexes with documents and data from the web, e.g. to generate answers from websites with documentation, blogs, or knowledge bases.
Installation and Setup#
Install the Apify API client for Python with
pip install apify-client
Get your Apify API token and either set it as an environment variable (
APIFY_API_TOKEN) or pass it to the
apify_api_tokenin the constructor.
You can use the
ApifyWrapper to run Actors on the Apify platform.
from langchain.utilities import ApifyWrapper
For a more detailed walkthrough of this wrapper, see this notebook.
You can also use our
ApifyDatasetLoader to get data from Apify dataset.
from langchain.document_loaders import ApifyDatasetLoader
