The platform bills your Noorle account for what your agents consume, as they consume it. One balance sits behind everything you run — every agent, every gateway, every workflow. There is no per-seat charge, so the size of your team is not an input to the bill. [noorle.com/pricing](https://noorle.com/pricing/) is the rate card. Rates are not repeated here: one published place means one thing to keep current. ## What gets recorded Every billable call writes a usage event carrying what the service was, how many units it used, and what produced it. Model spend is priced per model **and per route** — the same model reached a different way can carry different rates — with fresh input, cached input, cache-write input, and output metered as separate line items. Everything else meters on its own unit: per request, per second, per query, per hour, per GB-day. [Usage and limits](/docs/run/platform/usage-and-limits) has the detail. ## Where you read it **Usage & Billing** in the Portal, a month at a time: balance, free credits, current-month spend, spending cap, workspace and knowledge storage, top services, top capabilities, daily spend, and recent monthly statements. ## When the balance runs out The balance and the spending cap are enforced at the moment a run or an MCP request allocates its budget. An agent run with no budget available does not start; an MCP request with none is rejected with **402 Payment Required**. That is worth planning around if what you sell runs unattended: the stop lands on the next call, not at the end of a billing period. ## What you charge The meter measures your account's consumption. The price of the thing you sell is a separate decision, made by you and set outside the platform. Back to the overview.
