JioSaavn API

A high-performance unofficial API for JioSaavn, written in Python using the FastAPI framework. This API allows you to fetch DRM-free songs, cover art, lyrics, albums, playlists, artist information, and more.

Tech Stack

• Language: Python3
• Framework: FastAPI
• Libraries:

* requests: For making HTTP requests to the JioSaavn website. * pyDes: For decrypting encrypted media URLs. * pydantic: For data validation and serialization. * fastapi: For building the API. * uvicorn: For serving the API. * markdown: For rendering the README.md in the browser.

Architecture Overview

This API interacts with the JioSaavn website by scraping data and utilizing undocumented APIs. It then processes and formats the retrieved data, including decrypting media URLs, to provide a clean and consistent JSON response.

Data Flow:

• Request: A client sends a request to a specific API endpoint (e.g., /song/).
• Fetch: The API sends a request to the JioSaavn website to retrieve the relevant data.
• Process: The API processes the raw data, extracts necessary information, and formats it. This may include decrypting media URLs using pyDes and cleaning up strings.
• Response: The API returns the processed data as a JSON response to the client.

Design Choices

• FastAPI: Chosen for its speed, ease of use, and built-in features like automatic documentation generation.
• pydantic: Used for data validation and serialization, ensuring data integrity and consistency.
• Asynchronous Requests: Using requests to handle requests from JioSaavn Website.

Getting Started

• Clone the repository:

git clone https://github.com/anxkhn/jiosaavn-api

• Navigate to the project directory:

cd jiosaavn-api

• Run the application:

You have two options for running the application:

- Option 1: Run directly using FastAPI Install the dependencies and run the application using FastAPI (without Docker):

pip install -r requirements.txt      fastapi dev main.py

- Option 2: Run the application using Docker Alternatively, you can run the application in Docker using Docker Compose:

docker-compose up --build

• Access the application:

After running the application, you can access the following documentation pages:

- Swagger UI: http://localhost:8000/docs - ReDoc: http://localhost:8000/redoc

You can also visit the app directly at http://0.0.0.0:8000.

API Endpoints

Songs:

/song/: Search for songs.

- Query Parameters: - query: Search term for finding songs (required). - lyrics: Include song lyrics in the response (optional, default: False). - songdata: Fetch full song details or basic information (optional, default: True).

Example of a Song Response

Curl

curl -X 'GET' \
  'http://localhost:8000/song/?query=Chammak%20Challo&lyrics=false&songdata=true' \
  -H 'accept: application/json'

Request URL

http://localhost:8000/song/?query=Chammak%20Challo&lyrics=false&songdata=true

The response will contain details about the song "Chammak Challo" from the album Ra-One:

Notes:

• media_url: The 320kbps decrypted media URL (provides high-quality audio).
• mediapreviewurl: The 96kbps preview URL (for low-quality preview).

• There can be a .mp4 extension occasionally in the URLs. It does not denote a video; instead, it is just in .mp4 format with only an audio channel. Endpoints should handle it.

• /song/get: Retrieve a specific song by its ID.

* Query Parameters: * song_id: Unique identifier of the song (required). * lyrics: Include song lyrics in the response (optional, default: False).

Albums:

• /album/: Retrieve album details.

* Query Parameters: * query: Album URL or ID (required). * lyrics: Include song lyrics in the response (optional, default: False).

Playlists:

• /playlist/: Retrieve playlist details.

* Query Parameters: * query: Playlist URL or ID (required). * lyrics: Include song lyrics in the response (optional, default: False).

Lyrics:

• /lyrics/: Retrieve song lyrics.

* Query Parameters: * query: Song URL, link, or direct lyrics ID (required).

Health:

• /ping: Health check on all JioSaavn endpoints, including service-specific connectivity statuses.

• Note: Kindly ensure all endpoints are working properly before use. Check the health status using the /ping endpoint. If everything is functioning correctly, you should receive a response similar to the following:

{
        "msg": "Pong!",
        "status": "healthy",
        "details": [...]
    }

• TODO:

[ ] Enhance the /ping endpoint to include more comprehensive testing. This will involve validating actual media data (e.g., fetching and processing song, album, and playlist details) to ensure the full functionality of the services.
