Bandcamp Async API

A modern, asynchronous Python client for the Bandcamp API.

This project was created to implement a Bandcamp music provider for Music Assistant, enabling seamless integration of Bandcamp's music catalog into home audio systems.

Installation

Install from PyPI:

pip install bandcamp-async-api

Or using uv:

uv add bandcamp-async-api

Quick Start

import asyncio
from bandcamp_async_api import BandcampAPIClient

async def main():
    async with BandcampAPIClient(identity_token='7%09optional_identity_token%7D') as client:
        # Search for music
        results = await client.search("radiohead")
        print(f"Found {len(results)} results")

        # Get album details
        if results:
            album_result = next(r for r in results if r.type == "album")
            album = await client.get_album(album_result.artist_id, album_result.id)
            print(f"Album: {album.title} by {album.artist.name}")

        # Get artist information
        artist_result = next(r for r in results if r.type == "artist")
        artist = await client.get_artist(artist_result.id)
        print(f"Artist: {artist.name} - {artist.bio}")

if __name__ == '__main__':
    asyncio.run(main())

Authentication

For accessing user collections, you need to obtain an identity token from Bandcamp cookies:

from bandcamp_async_api import BandcampAPIClient

client = BandcampAPIClient(identity_token="your_identity_token")

Music Feed

The get_feed() method retrieves a personalized music feed containing new releases from followed artists, fan purchases, and fan picks. This endpoint requires authentication - you must provide an identity token.

import asyncio
from bandcamp_async_api import BandcampAPIClient, BandcampMustBeLoggedInError

async def main():
    async with BandcampAPIClient(identity_token='your_identity_token') as client:
        # Get your music feed
        feed = await client.get_feed()
        print(f"New stories: {len(feed.stories)}")
        print(f"Has more: {feed.has_more}")

        # Iterate through feed stories
        for story in feed.stories:
            print(f"  - {story.story_type}: {story.item_title} by {story.band_name}")

        # Access tracks with streaming URLs
        for track in feed.track_list:
            print(f"  Track: {track.title} - {track.streaming_url}")

        # Paginate through older stories
        if feed.has_more and feed.oldest_story_date:
            older_feed = await client.get_feed(older_than=feed.oldest_story_date)
            print(f"Older stories: {len(older_feed.stories)}")

if __name__ == '__main__':
    asyncio.run(main())

Feed Story Types

The feed contains different story types:

• np - New track/track release
• nr - New album release
• p - Fan purchase
• fp - Fan pick

Error Handling

The feed endpoint requires authentication. If you try to access it without an identity token, you'll receive a BandcampMustBeLoggedInError:

from bandcamp_async_api import BandcampAPIClient, BandcampMustBeLoggedInError

async def safe_get_feed():
    client = BandcampAPIClient()  # No identity token
    try:
        feed = await client.get_feed()
    except BandcampMustBeLoggedInError:
        print("Feed requires authentication - provide an identity token")

API Reference

Core Client

• BandcampAPIClient() - Main API client
• search(query: str) - Search Bandcamp
• get_album(artist_id, album_id) - Get album details
• get_track(artist_id, track_id) - Get track details
• get_artist(artist_id) - Get artist details
• get_collection_summary() - Get collection overview
• get_collection_items(collection_type, older_than_token, count, fan_id) - Get collection/wishlist/following items with pagination
• get_artist_discography(artist_id) - Get artist's complete discography
• get_feed(older_than) - Get personalized music feed with pagination support

Data Models

• SearchResultItem - Base search result
• BCAlbum - Album with tracks and metadata
• BCTrack - Individual track information
• BCArtist - Artist/band profile
• CollectionSummary - User's collection data
• CollectionItem - Individual collection item
• FollowingItem - Band/artist from following list

• FeedStory - Individual feed story (new release, fan purchase, etc.)
• FeedTrack - Track from feed with streaming URL
• FeedBandInfo - Band information referenced in feed
• FeedFanInfo - Fan information referenced in feed

Exceptions

• BandcampAPIError - Base API error
• BandcampNotFoundError - Resource not found
• BandcampBadQueryError - Invalid search query
• BandcampRateLimitError - Rate limit exceeded (includes retry_after attribute)

Error Handling

The client provides specific exception types for different error conditions:

from bandcamp_async_api import (
    BandcampAPIClient,
    BandcampNotFoundError,
    BandcampAPIError
)

async def safe_get_album(client, artist_id, album_id):
    try:
        return await client.get_album(artist_id, album_id)
    except BandcampNotFoundError:
        print("Album not found")
        return None
    except BandcampAPIError as e:
        print(f"API error: {e}")
        return None

Rate Limiting

When Bandcamp's API rate limit is exceeded, a BandcampRateLimitError is raised with a retry_after attribute indicating how many seconds to wait before retrying:

import asyncio
from bandcamp_async_api import BandcampAPIClient, BandcampRateLimitError

async def get_album_with_retry(client, artist_id, album_id, max_retries=3):
    for attempt in range(max_retries):
        try:
            return await client.get_album(artist_id, album_id)
        except BandcampRateLimitError as e:
            if attempt < max_retries - 1:
                wait_time = e.retry_after or 30
                print(f"Rate limited. Waiting {wait_time} seconds...")
                await asyncio.sleep(wait_time)
            else:
                raise

For automatic retries with exponential backoff, you can use the tenacity library:

from tenacity import retry, retry_if_exception_type, wait_exponential
from bandcamp_async_api import BandcampAPIClient, BandcampRateLimitError

@retry(
    retry=retry_if_exception_type(BandcampRateLimitError),
    wait=wait_exponential(multiplier=1, min=30, max=300)
)
async def get_album(client, artist_id, album_id):
    return await client.get_album(artist_id, album_id)
