Lusor bills two things: Your plan includes a monthly amount of each. See Pricing for the numbers, and Settings → Billing in the Lusor app for your balance.

​
Credits

Every agent session uses credits for the model’s work. How many depends on the task and on the model you choose. When your plan’s credits run low, upgrade your plan or add a credit pack in Settings → Billing. Credits from a credit pack are used after your plan’s credits.

​
Lusor Phone minutes

Lusor Phone minutes count time on your workspace’s Lusor Phones. They are shared by the whole workspace and reset every month.
  • Agent sessions on a Lusor Phone use minutes for the time the agent works on the phone.
  • Direct control of a Lusor Phone with an API key uses minutes too. Time is counted from your first action until 60 seconds after your last one. See Direct phone control.
  • Your own phone uses no minutes. Agent sessions on it still use credits for the model.

​
Overages

When your workspace has used its included minutes, the Overages setting decides what happens:
  • On: extra minutes are paid from your credits.
  • Off: Lusor Phone time stops at your included minutes.
Overages are off by default on the Free plan and on by default on paid plans. Workspace admins change the setting on the plan card in Settings → Billing.

​
When you run out

​
Before a session starts

If the workspace has no credits left, Lusor refuses new work before it starts. Sending a turn, starting a session, sending a follow-up message or answering the agent returns 402:
tier is your current plan and upgradeTo the next one up. A direct-control action on a Lusor Phone returns 402 credits_exhausted with resource: "phone_minutes" when the workspace is past its minutes and either has no credits left or has Overages off. The action is not sent to the phone.

​
During a session

When a session starts, Lusor notes the workspace’s credit balance. If the session’s model cost reaches that balance, the session stops partway: its status becomes failed and its error is credits_exhausted. To finish the work, add credits, then send the session a follow-up message such as “Carry on where you stopped.” The agent keeps what it did so far.

​
A Lusor Phone without a paid plan

402 with error: "billing_required" means the session’s Lusor Phone is not covered by an active paid plan. Check your Phone plan in Settings → Billing.
