GET /sys/balance
Balance of your account: how many requests are left and how much money is on it.
The two values refresh at different rates:
requestsis real time — it goes down with every call you make.amountis settled once per hour — spending is charged in whole hours, a few minutes after the hour ends. Between chargesamountlooks frozen even though you are spending. Top-ups are the exception: they appear within seconds.
So use requests for quota checks and low-balance alerts, and amount for
accounting. Calling this endpoint is free — it does not consume a request.
