Apify Actor Loader

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 loader runs a specific Actor and loads its results.

Usage

In this example, we’ll use the Website Content Crawler Actor, which can deeply crawl websites such as documentation, knowledge bases, help centers, or blogs, and extract text content from the web pages. The extracted text then can be fed to a vector index or language model like GPT in order to answer questions from it.

To use this loader, you need to have a (free) Apify account and set your Apify API token in the code.

from llama_index.core import Document
from llama_index.readers.apify import ApifyActor

reader = ApifyActor("<My Apify API token>")

documents = reader.load_data(
    actor_id="apify/website-content-crawler",
    run_input={
        "startUrls": [{"url": "https://docs.llamaindex.ai/en/latest/"}]
    },
    dataset_mapping_function=lambda item: Document(
        text=item.get("text"),
        metadata={
            "url": item.get("url"),
        },
    ),
)

This loader is designed to be used as a way to load data into LlamaIndex and/or subsequently used as a Tool in a LangChain Agent.

Apify Dataset Loader

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 loader loads documents from an existing Apify dataset.

Usage

In this example, we’ll load a dataset generated by the Website Content Crawler Actor, which can deeply crawl websites such as documentation, knowledge bases, help centers, or blogs, and extract text content from the web pages. The extracted text then can be fed to a vector index or language model like GPT in order to answer questions from it.

To use this loader, you need to have a (free) Apify account and set your Apify API token in the code.

from llama_index.core import Document
from llama_index.readers.apify import ApifyDataset

reader = ApifyDataset("<Your Apify API token>")
documents = reader.load_data(
    dataset_id="<Apify Dataset ID>",
    dataset_mapping_function=lambda item: Document(
        text=item.get("text"),
        metadata={
            "url": item.get("url"),
        },
    ),
)
