Hard budget ceilings for AI agents

Your agents get a hard budget.
Per task. Cross-provider. Tools included.

Provider spend caps stop at monthly totals for one vendor. AgentBill enforces the number that actually matters: what this job is allowed to cost, across every model and tool it touches, blocked before the money is spent.
