Velobase gives your AI application a fast, reliable credit system. Deposit credits for your users, freeze a budget before a model call, then settle the exact cost when you know it — without risking negative balances or double charges.

How Velobase works

Velobase acts as a credit bank between your application and your customers. You top up a customer’s balance, and your app deducts credits as users consume AI features.
1

Get an API key

Sign in to the Velobase Dashboard, create a project, and generate an API key under Project Settings → API Keys.
2

Deposit credits for a user

Call POST /v1/billing/deposit with a customer_id and an amount. Velobase creates the customer automatically if they don’t exist yet.
3

Charge credits for AI work

Use direct deduction for fixed-price tasks, or the freeze → consume flow for LLM calls where cost is only known after generation.
4

Track every transaction

Every operation is recorded in an immutable ledger. Query customer balances and audit charges in real time from the dashboard or API.

​
Choose a billing flow

Direct Deduction

Charge immediately when cost is known upfront — image generation, fixed-price API calls.

Staged Deduction

Freeze a maximum budget, then consume the actual cost — LLM inference, async tasks.

Depositing Credits

Top up customer balances, set expiry dates, and manage wallet categories.
