AgentKey bills through a subscription. Each plan includes a monthly credit allowance shared across every service your agent uses. If you use up your allowance before the month ends, additional usage is billed as overage at per-credit rates — your agent keeps working without interruption.

​
How it works

One plan

A single subscription covers every service — no per-provider signups or invoices.

Monthly credits

Your plan includes a credit allowance that resets each billing cycle.

Overage beyond it

Past your allowance, usage is billed per credit — no hard cutoff, no interruption.
Each tool has a known per-call cost in credits, surfaced when you describe it. Calls draw down your monthly allowance first, then bill as overage.

​
See the cost before you spend

Every find_tools and describe_tool result includes the per-call cost in credits. Before any bulk work, multiply that cost by your planned call count, and check your remaining allowance with the free account tool.
For work involving several calls or a meaningful credit estimate, confirm the plan and cost with the user before proceeding.

​
Managing your plan

Choose or change your plan, set overage limits, and review usage from the console. The account tool returns your remaining credits and upstream health at any time — and never costs credits to call.
Plan tiers, included allowances, and overage rates are shown in the console; each tool’s per-call cost appears in its describe output.
