The API is auto-correcting certain numbers to currencies
The service seems to be having some kind of training data bias for some inputs. Sending only numbers like 50000, 250000, 500000 etc., is returning $50,000, $250,000 and $500,000 respectively. This does not seem to happen for other numbers like 5000, 10000, etc. The service should never assume that a number denotes monetary value unless there is more context surrounding it.
