Yes, it is possible to create a program in Python that satisfies the requirements you have outlined. Here is a rough outline of how such a program might work:
|
|
|
|
The program will be written in Python 3 and be contained in a single file.
|
|
|
|
To record the Bitcoin price, the program will use the requests module to fetch the price data from the Binance API. The response from the API will be parsed to extract the mins and price values, which will be stored in an SQLite database along with the current timestamp, the symbol name, and the source of the data.
|
|
|
|
To ensure that the program fetches the price data at regular intervals, it will use a timer to check the time since the last data was fetched. If the time since the last fetch is greater than the mins value from the API response, the program will fetch new data.
|
|
|
|
To serve the price data via an HTTP/JSON API, the program will use the flask module to create a server that listens for incoming HTTP requests. The server will be configured to require token authentication, and will provide two endpoints: one for dumping the entire database as a JSON document, and another for dumping a subset of the data based on a provided timestamp.
|
|
|
|
To control the size of the database, the program will use a daily timer to rotate the database at midnight each day. This will involve creating a new database file and copying the data from the old database into the new one, then deleting the old database file.
|
|
|
|
To implement the program, you will need to use Python's threading module to create separate threads for the data gathering and API serving processes. This will allow the program to fetch data and serve requests concurrently, ensuring that the API is always available and up-to-date.

I hope this helps! Let me know if you have any other questions.
