Cross-venue arbitrage
curl --request GET \
  --url https://api.oddpool.com/arbitrage/current
Find markets where buying YES on one venue and NO on another costs less than 1 dollar combined. The gap is risk-free profit.
Example: “Will the Fed cut rates?” — YES is 42c on Kalshi, NO is 55c on Polymarket. Buy both for 97c. One side pays 1 dollar, so you pocket 3c per contract guaranteed.

Parameters

min_net_cents
float
default:"0"
Minimum net profit after fees, in cents.
minutes
integer
default:"10000"
Lookback window in minutes.

Example

curl -H "X-API-Key: your_api_key" \
  "https://api.oddpool.com/arbitrage/current?min_net_cents=0.5&minutes=10"

Response

net_cents is your per-contract profit after all fees.
