2. TRY END POINT USING CURL

• Get Current Price curl -X GET http://localhost:8000/price/BTC-USDT

• Get Price History curl -X GET http://localhost:8000/price/history?page=1&page_limit=10&currency=BTC-USDT

• Delete Price History curl -X DELETE http://localhost:8000/price/history

RUN PYTEST

To run PyTest on endpoints, run following command

cd .. && cd test
pytest endpoint_test.py
