Credits (Pay-as-you-go)

Credits let you use the API without a monthly subscription. Top up a balance, and it’s consumed as you make requests. Credits never expire.

How credits work

1. Top up credits from the Billing page
2. Create a credit key from the API Keys page or via POST /api/keys/credit
3. Use that key like any other API key
4. The platform tracks spend against your credit balance
5. When the balance runs out, top up again

Top-up amounts

Minimum $10. You can top up any amount from $10 upward.

Amount
$10
$25
$50

Pay with card (Stripe) or USDC on Base L2.

Credit key rate limits

Credit keys have fixed rate limits:

Limit	Value
RPM	60
Budget	Your topped-up balance

Unlike subscription keys, credit key budgets do not reset — the balance is consumed until depleted, then you top up again.

Multiple top-ups

Each top-up increases your credit key’s budget. For example:

• Top up $10 → balance is $10
• Use $3 → balance is $7
• Top up $25 → balance is $32

You keep the same credit key across top-ups.
