Two-way arbitrage detector API

Detects a two-way sure-bet (1/oddsA + 1/oddsB < 1) and computes the stake split for a target total that locks equal profit on either outcome, with guaranteed profit and ROI. Answers 'Is there an arbitrage between these two books?', 'How do I split my stake to lock a sure profit?'.
