Currencies Format

In the SpectroCoin API, all currency codes, both FIAT and cryptocurrency, must be specified using uppercase letters (e.g., "SOL", "BTC", "EUR", "USD"). If a request is made to an endpoint with a currency code in an incorrect format (e.g., lowercase or mixed case), the API will return an error response. The response includes details about the validation failure, structured as follows:

{
  "errorCode": "GEN_8",
  "category": "validation",
  "key": "entity_not_found",
  "defaultMessage": "Requested entity was not found.",
  "spanId": "382ec2e29d50544a",
  "traceId": "1ae3a8bb1d1bf7d3",
  "errorParameters": [
    {
      "key": "Id",
      "value": "id"
    }
  ]
}
