Grant and constraints of using rates dataset and conversion methods.

1. Grant of License

Subject to compliance with our usage metrics, we grant you a limited, non-exclusive, non-transferable, revocable license to request, download, and utilize exchange rates data in your software applications.

2. Permitted Uses

You may integrate the rates in web platforms, internal systems, mobile applications, and testing environments. You are encouraged to cache the data locally to enhance load times and minimize overall server dependency.

3. Restrictions

You shall not:

  • Sell, lease, or sub-license the raw database content as a standalone service.
  • Use the currency system to facilitate illegal financial transactions or market manipulation.
  • Reverse engineer the rate synchronization cron script or bypass security features.

4. Attribution Requirement

For public-facing applications using this API, developers must include a clear attribution note visible on the conversion screen (e.g., "Exchange rates powered by our local System API").

5. Termination

We reserve the right to suspend or terminate developer keys immediately upon breach of restrictions or failure to adhere to the terms.
