Building a Comedy Show Travel Planner with Hyperbrowser

Let's build a smart travel planner that combines AI planning with web automation to find comedy shows and flights. This agent will:

Break down complex travel planning into simple steps
Search for shows and check ticket availability
Find matching flights based on show dates
Keep track of progress across multiple sites

No more juggling between tabs or losing track of your planning process!

Prerequisites

You'll need:

A Hyperbrowser API key (sign up at hyperbrowser.ai)
An Anthropic API key
Python 3.9+

Store your API keys in a .env file:

HYPERBROWSER_API_KEY=your_hyperbrowser_key_here
ANTHROPIC_API_KEY=your_anthropic_key_here

import os
import json
from typing import List

from dotenv import load_dotenv
from hyperbrowser import AsyncHyperbrowser
from hyperbrowser.models import (
    StartBrowserUseTaskParams,
    CreateSessionParams,
    ScreenConfig,
)
from anthropic import AsyncAnthropic
from anthropic.types import MessageParam

from pydantic import BaseModel

from IPython.display import Markdown, display

load_dotenv()

Initialize Clients

Set up both Hyperbrowser for web automation and Anthropic for task planning.

hb = AsyncHyperbrowser(api_key=os.getenv("HYPERBROWSER_API_KEY"))
llm = AsyncAnthropic(api_key=os.getenv("ANTHROPIC_API_KEY"))

Smart Task Planning

First, we'll break down our travel planning into manageable steps. This helps ensure we:

Don't miss any important details
Handle tasks in the right order
Keep track of progress
Can recover from any failures

Usually, Browser Use already has a planner process that it uses internally, but for more complex steps, a separate planner that lets us review steps before execution can be helpful. Smaller steps are easier to process and handle, so this makes sure we give our Browser Use instance the best shot at success!

    step_info: str
    sub_steps: list[str]


class Task(BaseModel):

If you have to search for something, don't be too specific, but rather add steps so that the information gets filtered there. The response should have the overall task information, the steps information, the sub-steps in each step and the end-result to be achieved.

Let's Plan a Trip!

Watch as our agent:

Creates a detailed plan
Executes each step systematically
Keeps you updated on progress
Finds the best combination of show tickets and flights

Look for flight tickets two days arriving two days before the event, and leaving one day after the event. "

Make It Your Own

This pattern works for any event planning:

Different performers or shows
Various departure cities
Custom date ranges
Specific planning requirements

Conclusion

We've built a powerful travel planning agent that combines AI planning with web automation to:

Break down complex travel searches into simple steps
Search multiple sites for show tickets and flights
Track progress and maintain context between steps
Handle failures gracefully

This approach not only saves time but also ensures a systematic search across multiple sites - perfect for finding the best deals on shows and flights. More importantly, it shows how we can break down a process into smaller steps to increase our chances of success.

This pattern can be extended to other types of event planning or multi-step web tasks.

Happy planning! 🎭✈️
