Billing Mechanics & System Limits

Price is temporarily reserved upon task creation and charged only when the solve succeeds. Failed or timed-out tasks are released immediately; you are never charged.

Solved task solutions and tokens are preserved for exactly 1 hour following completion. Afterwards, records transition to "result expired" and payloads are purged.

60 task creations/min per key, 1,200 result polls/min per key (separate budgets), and maximum 20 concurrent tasks in progress per account.
