In this notebook, we will assume that we’re running a company selling a product - vacuum cleaners -, and we want to monitor our competitors, by looking at the positive and negative reviews that their products are receiving and latest product announcements.

​
Generate an API Key

To get started, generated an API key in the Twin dashboard and substitute the value of the variable twin_key below. 
import requests
import time

twin_key = "<your api key>"
browse_endpoint = "https://api.twin.so/browse"
task_endpoint = "http://api.twin.so/task/"
Define the websites we want to navigate 
name_of_competitors = ["Dyson", "Shark", "LG", "Samsung"]
We’ll define a helper function that waits until the task is completed. The /browse endpoint is asynchronous, therefore we need to poll /task/{taskId} until the task is completed 
def wait_for_tasks(task_ids):
    outputs = []
    latest_actions = {task_id: None for task_id in task_ids}
    remaining_tasks = set(task_ids)

    while remaining_tasks:
        for task_id in list(remaining_tasks):
            response = requests.get(url=task_endpoint + task_id + "?limit=1", headers={"x-api-key": twin_key})
            data = response.json()
            
            if data["status"] in {"COMPLETED", "FAILED"}:
                outputs.append(data["output"])
                remaining_tasks.remove(task_id)
            elif data["steps"] and data["steps"][0]["action"] and latest_actions[task_id] != data["steps"][0]["action"]:
                latest_actions[task_id] = data["steps"][0]["action"]
                print(f"Task {task_id}: {latest_actions[task_id]}")
        
        time.sleep(1)
    
    return outputs

​
Amazon reviews

For the first step, we’ll check Amazon to find the reviews 
def launch_amazon_task():
    amazon_task_ids = []

    for competitor in name_of_competitors:
        print(f"Getting reviews for {competitor}")
        response = requests.post(
            url=browse_endpoint,
            headers={"x-api-key": twin_key},
            json={
                "goal": f"Find the latest reviews for {competitor}'s most popular vacuum cleaner - summarize the points made in the most positive and negative ones",
                "startUrl": "https://www.amazon.com/",
            },
        )
        amazon_task_ids.append(response.json()["taskId"])
    return amazon_task_ids

amazon_task_ids = launch_amazon_task()
amazon_reviews = wait_for_tasks(amazon_task_ids)

for review, competitor in zip(amazon_reviews, name_of_competitors):
    print(f"# Reviews for {competitor}")
    print(review)
    print("-"*100)
    print("\n\n")

​
Latest announcements

Now we’ll find what are the latest announcements by each company using Google News 
def launch_latest_announcements_task():
    latest_announcements_task_ids = []

    for competitor in name_of_competitors:
        print(f"Getting latest announcements for {competitor}")
        response = requests.post(
            url=browse_endpoint,
            headers={"x-api-key": twin_key},
            json={
                "goal": f"Find the latest product announcements of {competitor}, by searching for '{competitor} product announcements",
                "startUrl": "https://news.google.com/",
            },
        )
        latest_announcements_task_ids.append(response.json()["taskId"])
    return latest_announcements_task_ids

latest_announcements_task_ids = launch_latest_announcements_task()
latest_announcements = wait_for_tasks(latest_announcements_task_ids)
for announcement in latest_announcements:
    print(announcement)
    print("\n\n")
