Tourist Framework

Tourist🤳

An open-source, low-cost, serverless application for SERP extraction and web scraping.

Work on your LLM projects without worrying about credits, subscriptions, or rate-limits. Tourist is a free alternative to many mainstream SERP and web scraping API services. Run Tourist on your machine or deploy it into your own AWS account.

[!IMPORTANT]
Tourist is still in early development. Features and API's may change unexpectedly.

Overview

Tourist has both Service and Client components. The Service (HTTP API) handles requests from the Client (your app, agent, or scraper scripts). You're in control of both components, and so none of your data is ever stored by third parties.

Service

Local deployment (for testing...)

[!TIP]
It is recommended to use Docker for running Tourist locally due to the various dependencies required to do headless browsing.

Run the Tourist service on your local machine for testing or prototyping:

1. Have Docker installed
2. Clone this repo
3. make tourist-local - builds and runs the container on your machine

Check the docs at http://localhost:8000/docs

AWS deployment (for real...)

Deploy your own instance of Tourist into AWS with Terraform:

1. Have Docker installed
2. Clone this repo
3. Have an AWS account with credentials copied to .env.aws in the root of this project
4. make tourist-iac-interactive
5. terraform apply - deploys the infrastructure into your AWS account

Use your endpoint: https://<uuid>.execute-api.us-east-1.amazonaws.com/main (available in terraform outputs)

[!WARNING]
Tourist uses serverless infrastructure to keep costs extremely low; however depending on how heavily you use your API, these costs will not be $0.00.

[!IMPORTANT]
Tourist uses the X-SECRET authorization header to protect your API, you should set this value in terraform/aws/terraform.tfvars

Client

Build your own LLM tools, web scraping apps, or automated testing workflows with the Tourist client.

Python

You can use the python client to interact with your Tourist service. Check out the examples folder for the complete code.

pip install tourist

LLM Tools

For example, create a LangChain Tool for your LLM Agent.

from bs4 import BeautifulSoup as bs
from tourist.core import TouristScraper
from langchain_core.tools import tool

# Assumes you're running locally,
# change this to your cloud endpoint if you've deployed via terraform.
scraper = TouristScraper(
    "http://localhost:8000",
    secret="doesntmatterlocally",  # authorization secret  
    concurrency=1,  # control concurrent searches/scrapes
)


@tool
def scrape_tool(url: str) -> str:
    """
    A web scraper. 
    Useful for when you need to answer questions related the contents of a website or URL.
    Input should be a URL.
    """
    results = scraper.get_page(url)
    if source_html := results.get("source_html"):
        soup = bs(source_html, "html.parser")
        return soup.get_text()
    else:
        return "Could not scrape that page. Try again."


@tool
def search_tool(query: str) -> str:
    """
    A search tool.
    Useful for when you need to answer questions about current events, people, places, or things.
    Input should be a search query.
    """
    results = scraper.get_serp(query, max_results=3):
    return " ".join([r["content"] for r in results])


# ... use the tools

Selenium

You can submit selenium scripts (human or AI-generated) to Tourist for execution.

from pprint import pprint

from tourist.core import TouristScraper


scraper = TouristScraper("http://localhost:8000", "no-secret")

my_selenium_code = """
# `driver`, a selenium `webdriver.Chrome` object, is available in globals
driver.get("https://www.example.com")
html = driver.page_source
# any key:values stored in `actions_output` will be available in the response
actions_output["html"] = html
actions_output["current_url"] = driver.current_url
"""

result = scraper.get_page_with_actions(my_selenium_code)
assert result["current_url"] == "https://www.example.com/"
pprint(result["html"])
