Polygon Stock Middleware Backend Endpoints

[theDe-bugger]

Description

Need a backend endpoint that the site can access to test the crypto arbitrage strategies for a specific currency, two exchanges, and time frame.

Overall:

• Gurik made an endpoint similar to this for cryptos, feel free to discuss this with him
• pretty simple, just use our api key thats in the server folder and call polygon for corresponding data requests
• you can start by throwing a 400 error for any issues that come up, but will need to specify error codes for diff errors

We need to make GET request!

Endpoint

'/api/stock'

Params

• stock ticker
• start datetime
• end datetime

Return

• the data as received from polygon

• note that this return could be fairly heavy and lead to a bottleneck
• what are some ways you can address this? data aggregation? limit the data request to just a specific time period?

Example Call

GET /api/stock
with params:

• stock ticker = AAPL
• start = "01/01/2023 10:00:00"
• end = "09/09/2023 18:00:00"

Return results the same way polygon does
