BachtrackAPI

A Python web scraper and REST API for extracting classical music opera events from Bachtrack.com.

Overview

BachtrackAPI provides two complementary ways to access opera event data:

1. Scraper Module - Direct web scraping of Bachtrack opera listings
2. FastAPI Backend - RESTful API endpoints for searching and filtering events

Search by work ID (e.g., 12285 for Gianni Schicchi) or freetext (e.g., "La Traviata").

Installation

pip install -r requirements.txt

Quick Start

1. Using the Scraper Directly

from scraper.scraper import BachtrackScraper

scraper = BachtrackScraper()

# Search by work ID
events = scraper.search_operas(12285)  # Gianni Schicchi
print(f"Found {len(events)} events")

# Search by freetext
events = scraper.search_operas("La Traviata")
for event in events:
    print(f"{event['title']} - {event['city']} @ {event['venue']}")

Output:

Found 28 events
Gianni Schicchi - Berlin @ Deutsche Oper
Gianni Schicchi - Winterthur @ Stadttheater Winterthur
...

2. Using the FastAPI Backend

Start the server:

uvicorn api.main:app --reload

Example API Requests:

# Freetext search
curl "http://localhost:8000/api/v1/events/get_operas?q=gianni%20schicchi"

# Work ID search
curl "http://localhost:8000/api/v1/events/get_operas?q=12285"

# POST search
curl -X POST "http://localhost:8000/api/v1/events/search" \
  -H "Content-Type: application/json" \
  -d '{"work_id": 12285}'

Response:
