Soap client for Here Comes the Bus

hcb_soap_client

A Python async SOAP client for the "Here Comes the Bus" API, used to track school bus locations and schedules.

Installation

pip install hcb_soap_client

Or install from source:

git clone https://github.com/pcartwright81/hcb_soap_client.git
cd hcb_soap_client
pip install -e .

Usage

Basic Usage (Context Manager - Recommended)

Using the async context manager is the most efficient approach as it reuses the HTTP session across multiple requests:

import asyncio
from hcb_soap_client import HcbSoapClient

async def main():
    async with HcbSoapClient() as client:
        # Get school ID from school code
        school_id = await client.get_school_id("YOUR_SCHOOL_CODE")

        # Login and get parent/account info
        account = await client.get_parent_info(school_id, "username", "password")
        print(f"Account ID: {account.account_id}")
        print(f"Students: {[s.first_name for s in account.students]}")

        # Get bus stop info for a student
        for student in account.students:
            # Use AM_ID for morning routes, PM_ID for afternoon
            stops = await client.get_stop_info(
                school_id,
                account.account_id,
                student.student_id,
                HcbSoapClient.AM_ID  # or HcbSoapClient.PM_ID
            )

            if stops.vehicle_location:
                print(f"Bus location: {stops.vehicle_location.address}")
                print(f"Speed: {stops.vehicle_location.speed} mph")

asyncio.run(main())

Simple Usage (Without Context Manager)

For one-off requests, you can use the client without a context manager. Note that this creates a new HTTP session for each request:

async def simple_example():
    client = HcbSoapClient()
    school_id = await client.get_school_id("YOUR_SCHOOL_CODE")

Using a Custom Session

You can provide your own aiohttp.ClientSession for advanced use cases:

import aiohttp

async def custom_session_example():
    async with aiohttp.ClientSession() as session:
        client = HcbSoapClient(session=session)
        school_id = await client.get_school_id("YOUR_SCHOOL_CODE")
