fast-api-task

This is a test project, that implements an asynchronous API service that:

• Provides an authenticated FastAPI endpoint to query Tao dividends from the Bittensor blockchain
• Caches blockchain query results in Redis for 2 minutes
• Optionally triggers background stake/unstake operations based on Twitter sentiment:
• Queries Twitter via Datura.ai API for tweets about the subnet
• Analyzes tweet sentiment using Chutes.ai LLM
• Stakes or unstakes TAO proportional to sentiment score (-100 to +100)
• Uses Celery workers to handle async blockchain and sentiment analysis tasks
• Stores historical data in a high-concurrency asynchronous database

The architecture follows modern async patterns:

• FastAPI handles HTTP requests
• Redis serves as cache and message broker
• Celery workers process background tasks
• Async database stores results
• Docker containers orchestrate all components

Usage

1. Clone it git clone git@github.com:Kulv3r/fast-api-task.git
2. Do cp .env_example .env and update API keys and secrets (if needed) there
3. Run it: docker-compose up
4. Do the DB migrations: docker-compose run --rm backend alembic upgrade head
