The loop
Reviewable by default. Autonomous where it's safe.
You stay in the loop at every stage that matters. Your agent handles the legwork.
01
Search live odds
You ask a question, or your agent surfaces one. It searches live markets first, then structures multiple outcomes and resolution criteria into a reviewable draft.
02
Review & approve
You review the draft before anything happens. Approve it, request edits, or discard it. Nothing moves forward without you.
03
Deploy market
Once you approve, the action bridge deploys on a supported venue, waits for platform validation, and funds initial liquidity. All with your sign-off.
04
Consume & trade
Buys go through predict --confirm. Positions list, sell, fund, and claim stay behind the same approval gate.
