Welcome to Parsera

Parsera is a lightweight Python library for scraping websites with LLMs.
You can run clone and run it locally or use an API, which provides more scalable way and some extra features like built-in proxy.

Installation

pip install parsera
playwright install

Basic usage

If you want to use OpenAI, remember to set up OPENAI_API_KEY env variable. You can do this from python with:

import os

os.environ["OPENAI_API_KEY"] = "YOUR_OPENAI_API_KEY_HERE"

Next, you can run a basic version that uses gpt-4o-mini

from parsera import Parsera

url = "https://news.ycombinator.com/"
elements = {
    "Title": "News title",
    "Points": "Number of points",
    "Comments": "Number of comments",
}

scraper = Parsera()
result = scraper.run(url=url, elements=elements)

result variable will contain a json with a list of records:

[
   {
      "Title":"Hacking the largest airline and hotel rewards platform (2023)",
      "Points":"104",
      "Comments":"24"
   },
    ...
]

There is also arun async method available:

result = await scrapper.arun(url=url, elements=elements)

Running with CLI

Before you run Parsera as command line tool don't forget to put your OPENAI_API_KEY to env variables or .env file

Usage

You can configure elements to parse using JSON string or FILE. Optionally, you can provide FILE to write output.

python -m parsera.main URL {--scheme '{"title":"h1"}' | --file FILENAME} [--output FILENAME]
