PROJECT TERMINATED:

lack of infra, need gpu to compute, usecase is very limited

Music Generation API

A FastAPI-based service for AI music generation using Replicate's MusicGen model.

tester@gmail.com pass@123 --user_id = 4 2June -- proj_id = 5

Prerequisites

• Docker and Docker Compose
• Replicate API token (get one from replicate.com)
• Python 3.9+ (for local development)

Environment Setup

1. Clone this repository
2. Copy the .env.example to .env (if it doesn't exist already)
3. Update the .env file with your Replicate API token:

   REPLICATE_API_TOKEN=your_replicate_token_here
   REPLICATE_MODEL_ID=meta/musicgen:7a76a8258b23fae65c5a22debb8841d1d7e816b75c2f24218cd2bd8573787906
   MUSICGEN_MODEL_ID=facebook/musicgen-small
   

Starting the Services

Using Docker (Recommended)

Start all services with a single command:

docker-compose up -d

This will start:

• PostgreSQL database
• Redis for Celery
• FastAPI application
• Celery worker
• Flower (Celery monitoring)

To check if all services are running:

docker-compose ps

Verify Service Status

Check API service logs:

docker-compose logs -f api

Check Celery worker logs:

docker-compose logs -f celery_worker

Testing the Replicate API Connection

You can test if your Replicate API token is working correctly by using the test endpoint:

curl -X POST http://localhost:8000/api/v1/test/test-replicate-connection/

Or test the full audio generation:

For Windows Command Prompt:

curl -X POST http://localhost:8000/api/v1/test/test-generate/ -H "Content-Type: application/json" -d "{\"prompt\": \"Upbeat electronic music\", \"duration\": 5}"

For PowerShell:

Invoke-WebRequest -Uri http://localhost:8000/api/v1/test/test-generate/ -Method POST -Headers @{"Content-Type"="application/json"} -Body '{"prompt": "Upbeat electronic music", "duration": 5}'

For Linux/Mac/Git Bash:

curl -X POST http://localhost:8000/api/v1/test/test-generate/ \
  -H "Content-Type: application/json" \
  -d '{"prompt": "Upbeat electronic music", "duration": 5}'

Checking Environment Variables

To verify environment variables in containers:

# Check Replicate API token (masked for security)
docker-compose exec api bash -c 'echo ${REPLICATE_API_TOKEN:0:4}...${REPLICATE_API_TOKEN:(-4)}'

# Check Replicate model ID
docker-compose exec api bash -c 'echo $REPLICATE_MODEL_ID'

# Check MusicGen model ID
docker-compose exec api bash -c 'echo $MUSICGEN_MODEL_ID'

Stopping Services

Stop all services:

docker-compose down

To stop and remove volumes (will delete database data):

docker-compose down -v

Local Development

For local development without Docker:

1. Install dependencies:

   pip install -r requirements.txt

2. Set environment variables:

   export REPLICATE_API_TOKEN=your_token_here
   export RUNNING_LOCALLY=true

3. Run the API:

   uvicorn app.main:app --reload --host 0.0.0.0 --port 8000

4. Run Celery worker (in a separate terminal):

   celery -A app.celeryworker.worker worker -l info

API Documentation

Once the API is running, you can access the interactive documentation at:

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