Balance & billing

Generation usage is billed against a prepay balance, priced per second of inference. Check your balance and your rate card at any time with a single GET request.

Field	Type	Required	Description
balance_usd	number	always	Your current prepay balance in USD. May be slightly negative — see overdraft below.
min_balance_usd	number	always	Minimum balance (currently `$1.00`) required to start a new job.
rates	object	always	Your rate card: USD per second of inference, keyed by serving instance type.

Pricing rates

Rates are quoted in USD per second of inference, keyed by the serving instance type. The platform picks the instance for each job — your rate card is always in rates, so read your price from the response rather than hardcoding it.

Instance	USD per second	≈ USD per minute
`g5`	$0.000844	$0.0506
`g6e`	$0.001556	$0.0934
`g7e`	$0.002333	$0.1400

How billing works

Prepay balance. Usage is deducted from a balance you top up in advance on the dashboard, paid via Stripe. Preset top-ups are $10, $25, and $100, or any custom amount between $1 and $1,000. There is no public top-up endpoint.
Minimum balance. Creating a new job requires balance_usd ≥ min_balance_usd (currently $1.00). Below that, the request fails with 402 insufficient_balance.
You pay only for success. Usage settles per second, and only on SUCCEEDED jobs. The billed window runs from capacity allocation to inference finish, rounded up to the whole second. FAILED and CANCELED jobs cost nothing.
Overdraft is accepted. Settlement can drive the balance slightly negative — a job that already started always finishes. Only new jobs are gated by the minimum balance.

For the exact charge applied to a finished job, compare created_at against your balance history after settlement; the rates object in this response is the authoritative pricing source.
