Application that connects to exchanges thru ccxt library and obtain prices from cryptocurrency exchange.

Default exchange used in this project is kucoin. Base currency is USDT. Both these values can be changed in docker-compose.yml file or in settings.py as default value.

Docs to this API is accessible on URL http://localhost:8899/docs and is done with Swagger.

Install and run:

docker-compose up

Application is exposed on port 8899 and has two endpoints:

• GET /price/{currency}
• GET /price/history?page={page}

Postgres database is exposed on port 5432 and credentials if needed could be found in config/default.conf file. I would strongly suggest storing passwords in some tools for secrets such as Vault, but it is out of the scope of this project.

To run tests:

docker-compose -f docker-compose.test.yml up

Code formatting is done by Black formatter to format the Python files.

Set of pre-commit hooks to apply Black, check YAML and Markdown files, etc. is provided. You can install pre-commit with pip or brew. Then you can install hooks itself with command: pre-commit install --install-hooks in your repo folder.
