Futuur supports two trading modes: play money for risk-free testing and real money for live trading. You select the mode via the currency_mode parameter and specify the currency when placing orders.

​
Supported currencies

OOM (play money)

Virtual currency with no real-world value. Use OOM to explore the API, test your integration, and practice trading without any financial risk.

USDC, USDT, USD (real money)

Real stablecoins and fiat currency for live prediction markets. Subject to country restrictions.

​
currency_mode parameter

Many endpoints accept a currency_mode query parameter that controls which trading environment you interact with.
ValueDescription
play_moneyReturns data and places orders in the OOM (virtual) environment
real_moneyReturns data and places orders in the real money environment
The currency_mode parameter affects endpoints that list events, retrieve order books, and place orders. Omitting it typically defaults to play_money. 
# Browse real money events
GET /events/?currency_mode=real_money

# Browse play money events
GET /events/?currency_mode=play_money
Start with currency_mode=play_money during development. It lets you test the full order lifecycle — placing, filling, and canceling orders — without real funds.

​
Specifying currency when placing orders

When you create an order via POST /orders/, include the currency field to specify which currency to use. 
{
  "market": 42,
  "side": "bid",
  "position": "l",
  "amount": 100,
  "currency": "OOM",
  "price": null
}
Use USDC or USDT for real money orders: 
{
  "market": 42,
  "side": "bid",
  "position": "l",
  "amount": 10.00,
  "currency": "USDC",
  "price": 0.60
}
The currency value you supply must match the currency_mode of the event you are trading on. Mixing OOM with a real money event (or vice versa) will return an error.

​
Country restrictions

Real money trading (USDC, USDT, USD) is not available in all countries. If your account or IP address is associated with a restricted region, real money order placement will be rejected.Use currency_mode=play_money if you are in a restricted region or building an application that does not require real money trading.
Play money (OOM) is available everywhere with no restrictions.
