The MtGox API provides methods to access information from the market, place orders, and more.
Two APIs are currently available:
Number Formats
In the "old API", currency- and amount-values (price, volume,...) were given as float. These values are likely being deprecated and replaced by fields of the same name with "_int" as suffix. These are fixed-decimal, so you have to move the decimal point yourself (divide). The exponent differs based on the kind of the value.
In order to convert the int to a decimal you can...
| kind of field | ...divide by | ...multiply by |
|---|---|---|
| BTC (volume, amount) | 1E8 (100,000,000) | 0.00000001 |
| USD (price) | 1E5 (100,000) | 0.00001 |
| JPY (price) | 1E3 (1,000) | 0.001 |
Implementation advice: it's probably best to use int or Decimal (if your language/db offers such a type) in your clients. Using float will likely lead to nasty rounding problems.
Currency Symbols
List of the currency symbols available with the API:
USD, AUD, CAD, CHF, CNY, DKK, EUR, GBP, HKD, JPY, NZD, PLN, RUB, SEK, SGD, THB
Date and time
Most dates you will find in mtgox API are UNIX time
