All market prices are quoted as probabilities (0.00 to 1.00), but amounts are in your chosen currency.

​
Supported currencies

  • USD — US Dollar (default).
  • NGN — Nigerian Naira.

​
Currency base multiplier

Each currency has a base multiplier that determines how probabilities convert to costs:
CurrencyBase multiplierPrice of 0.65Winning payout
USD1$0.65/share$1.00/share
NGN100₦65.00/share₦100.00/share
The cost per share is: price × base multiplier. Losing shares pay out 0.00.

​
Specifying currency

Add the currency query parameter to your requests: 
# Get events with prices in NGN
GET /v1/pm/events?currency=NGN

# Get a specific event in USD (default)
GET /v1/pm/events/evt_123?currency=USD

# Place an order in NGN
POST /v1/pm/events/evt_123/markets/mkt_456/orders
{
  "side": "BUY",
  "outcome": "YES",
  "amount": 10000,
  "currency": "NGN"
}
If you don’t specify a currency, USD is used by default.

​
Base multiplier vs. exchange rate

The base multiplier applies to trading amounts — share prices, order costs, and display values. It converts probabilities to currency-denominated costs (e.g., a price of 0.65 costs 65.00 NGN per share). The following are converted from USD using the live exchange rate, not the base multiplier:
  • Liquidity reward and maker rebate payouts
  • Eligibility thresholds like minNotionalOrderSize and minPayoutUsd (evaluated in USD internally, then converted at the current rate)
