## How it works

Every hour on **9 and 39 minute** app checks if rates data in db is expired (updated yesterday or even older)

and if true, _update currency rates_:

1. Get data of specified item on steammarket for each needed currency.

2. Calculate exchange rates by comparing item price in previously fetched currencies.

3. Save data to db 😎.

> [!WARNING]

> It is possible to get max 4 currencies for each schedule wake up due to `Steam` rate limit.

## API

All currency rates eval to 1 USD 💵.

> [!IMPORTANT]

> All routes have `Expires` ⌛ header

> So please consider using a caching mechanism to avoid unnecessary requests to the service as its resources are limited.
