# PAR Scrape
[](https://pypi.org/project/par_scrape/)
[](https://pypi.org/project/par_scrape/)
PAR Scrape is a versatile web scraping tool with options for Selenium or Playwright, featuring AI-powered data extraction and formatting.
[](https://buymeacoffee.com/probello3)
## Screenshots
## Features
- Web scraping using Playwright or Selenium
- AI-powered data extraction and formatting
- Supports multiple output formats (JSON, Excel, CSV, Markdown)
- Customizable field extraction
- Token usage and cost estimation
- Prompt cache for Anthropic provider
## Known Issues
- Selenium silent mode on windows still shows message about websocket. There is no simple way to get rid of this.
- Providers other than OpenAI are hit-and-miss depending on provider / model / data being extracted.
## Prompt Cache
- OpenAI will auto cache prompts that are over 1024 tokens.
- Anthropic will only cache prompts if you specify the --prompt-cache flag. Due to cache writes costing more only enable this if you intend to run multiple scrape jobs against the same url, also the cache will go stale within a couple of minutes so to reduce cost run your jobs as close together as possible.
## Prerequisites
To install PAR Scrape, make sure you have Python 3.11.
### [uv](https://pypi.org/project/uv/) is recommended
#### Linux and Mac
```bash
curl -LsSf https://astral.sh/uv/install.sh | sh
```
#### Windows
```bash
powershell -ExecutionPolicy ByPass -c "irm https://astral.sh/uv/install.ps1 | iex"
```
## Installation
### Installation From Source
Then, follow these steps:
1. Clone the repository:
```bash
git clone https://github.com/paulrobello/par_scrape.git
cd par_scrape
```
2. Install the package dependencies using uv:
```bash
uv sync
```
### Installation From PyPI
To install PAR Scrape from PyPI, run any of the following commands:
```bash
uv tool install par_scrape
```
```bash
pipx install par_scrape
```
### Playwright Installation
To use playwright as a scraper, you must install it and its browsers using the following commands:
```bash
uv tool install playwright
playwright install chromium
```
## Usage
To use PAR Scrape, you can run it from the command line with various options. Here's a basic example:
Ensure you have the AI provider api key in your environment.
You can also store your api keys in the file `~/.par_scrape.env` as follows:
```bash
GROQ_API_KEY= # is required for Groq. Get a free key from https://console.groq.com/
ANTHROPIC_API_KEY= # is required for Anthropic. Get a key from https://console.anthropic.com/
OPENAI_API_KEY= # is required for OpenAI. Get a key from https://platform.openai.com/account/api-keys
GITHUB_TOKEN= # is required for GitHub Models. Get a free key from https://github.com/marketplace/models
GOOGLE_API_KEY= # is required for Google Models. Get a free key from https://console.cloud.google.com
LANGCHAIN_API_KEY= # is required for Langchain Langsmith tracing. Get a free key from https://smith.langchain.com/settings
AWS_PROFILE= # is used for Bedrock authentication. The environment must already be authenticated with AWS.
# No key required to use with Ollama models.
```
### Running from source
```bash
uv run par_scrape --url "https://openai.com/api/pricing/" -f "Title" -f "Description" -f "Price" -f "Cache Price" --model gpt-4o-mini --display-output md
```
### Running if installed from PyPI
```bash
par_scrape --url "https://openai.com/api/pricing/" -f "Title" -f "Description" -f "Price" -f "Cache Price" --model gpt-4o-mini --display-output md
```
### Options
- `--url`, `-u`: The URL to scrape or path to a local file (default: "https://openai.com/api/pricing/")
- `--fields`, `-f`: Fields to extract from the webpage (default: ["Model", "Pricing Input", "Pricing Output"])
- `--scraper`, `-s`: Scraper to use: 'selenium' or 'playwright' (default: "playwright")
- `--headless`, `-h`: Run in headless mode (for Selenium) (default: False)
- `--wait-type`, `-w`: Method to use for page content load waiting [none|pause|sleep|idle|selector|text] (default: sleep).
- `--wait-selector`, `-i`: Selector or text to use for page content load waiting.
- `--sleep-time`, `-t`: Time to sleep (in seconds) before scrolling and closing browser (default: 5)
- `--ai-provider`, `-a`: AI provider to use for processing (default: "OpenAI")
- `--model`, `-m`: AI model to use for processing. If not specified, a default model will be used based on the provider.
- `--prompt-cache`: Enable prompt cache for Anthropic provider. (default: False)
- `--display-output`, `-d`: Display output in terminal (md, csv, or json)
- `--output-folder`, `-o`: Specify the location of the output folder (default: "./output")
- `--silent`, `-q`: Run in silent mode, suppressing output (default: False)
- `--run-name`, `-n`: Specify a name for this run
- `--version`, `-v`: Show the version and exit
- `--pricing`: Enable pricing summary display ('details','cost', 'none') (default: 'none')
- `--cleanup`, `-c`: How to handle cleanup of output folder (choices: none, before, after, both) (default: none)
- `--extraction-prompt`, `-e`: Path to alternate extraction prompt file
- `--ai-base-url`, `-b`: Override the base URL for the AI provider.
### Examples
1. Basic usage with default options:
```bash
par_scrape --url "https://openai.com/api/pricing/" -f "Model" -f "Pricing Input" -f "Pricing Output" --pricing -w text -i gpt-4o
```
2. Using Playwright and displaying JSON output:
```bash
par_scrape --url "https://openai.com/api/pricing/" -f "Title" -f "Description" -f "Price" --scraper playwright -d json --pricing -w text -i gpt-4o
```
3. Specifying a custom model and output folder:
```bash
par_scrape --url "https://openai.com/api/pricing/" -f "Title" -f "Description" -f "Price" --model gpt-4 --output-folder ./custom_output --pricing -w text -i gpt-4o
```
4. Running in silent mode with a custom run name:
```bash
par_scrape --url "https://openai.com/api/pricing/" -f "Title" -f "Description" -f "Price" --silent --run-name my_custom_run --pricing -w text -i gpt-4o
```
5. Using the cleanup option to remove the output folder after scraping:
```bash
par_scrape --url "https://openai.com/api/pricing/" -f "Title" -f "Description" -f "Price" --cleanup --pricing
```
6. Using the pause option to wait for user input before scrolling:
```bash
par_scrape --url "https://openai.com/api/pricing/" -f "Title" -f "Description" -f "Price" --pause --pricing
```
7. Using Anthropic provider with prompt cache enabled and detailed pricing breakdown:
```bash
par_scrape -a Anthropic --prompt-cache -d csv -p details -f "Title" -f "Description" -f "Price" -f "Cache Price"
```
