v0.1.16 — October 27, 2026

New feature

Combos

A combo is a single position built from 2 to 10 legs, where each leg is one market outcome. The whole slip is priced as one price and multiplier, and it wins only if every leg wins. You can cash out an open combo before any of its games start. Combos are not the same as combined events. See Combos for pricing, voided legs, settlement, and cashout rules.

New WebSocket channel

`combos` on `/ws/v1/user`

A private channel for your own combos. Subscribe with {"type": "subscribe", "channel": "combos", "auth": {"apiKey": "pk_live_..."}}.

combo_placed — sent once when you place a combo.
combo_updated — sent on every later state change: a game starting, the cashout window closing, settlement, cashout, and the payout landing.

Each event carries the full current state of the combo. See Combos WebSocket.
