Apify

This page covers how to use Apify within LangChain.

Overview

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 ApifyWrapper as apify_api_token in the constructor.

Wrappers

Utility

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.

Loader

You can also use our ApifyDatasetLoader to get data from Apify dataset.

from langchain.document_loaders import ApifyDatasetLoader

For a more detailed walkthrough of this loader, see this notebook.
