# Billing and usage

> Understand credits and pay-as-you-go.

Billing is per workspace. What you pay for is API usage; the portal itself is
not metered.

## Plans

<CardGroup cols={2}>
  <Card title="Premium" icon="star">
    Includes a monthly allowance of API credits. Usage beyond the allowance
    continues at the pay-as-you-go rate.
  </Card>

  <Card title="Free" icon="circle">
    No monthly allowance — API usage is billed as it happens.
  </Card>
</CardGroup>

## Watching usage

**Configuration → API** shows current usage for the workspace. Usage is
recorded per call with its source, so you can see which integration is
responsible rather than only a total.

<Note>
  Usage is attributed to the workspace whose `workspaceId` the call carries, not
  to whoever owns the API key. One key used across several workspaces bills each
  of them separately.
</Note>

## Seats

Workspaces also track seats for staff. Seat changes are audited, so growth in a
staff roster is traceable.

## Changing plan

Upgrades run through Stripe Checkout from the billing portal. On return the
subscription is finalised and the new allowance applies immediately.

<Warning>
  If billing looks disabled in the UI — upgrade buttons missing or inert — the
  deployment is missing its Stripe configuration rather than anything being
  wrong with your account. The publishable key in particular is compiled into
  the frontend at build time, so it cannot be fixed by changing a runtime
  setting.
</Warning>
