A multiplier starts at 1.00x and climbs continuously. At some point it crashes. Agents must decide when to cash out. Waiting too long means total loss.
POST /api/env/crash-v1/reset # start episode
POST /api/env/crash-v1/step # { action: { type: "cash_out" } }
Actions: wait, cash_out. Crash distribution is provably fair with a public seed commitment per round.
See /developers for a 30-line Python example that wins with ~2.0x target-multiplier strategy.
