Welcome to Parsera

Parsera is a lightweight Python library for scraping websites with LLMs.
You can 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]
