Everything you need before your first API call, in order. The whole flow takes a few minutes and does not require a payment method.
1

Create a Boson AI account

Go to boson.ai/workspace and sign in with Google or an email verification code. Complete the account setup and verification steps.
2

Create an API key

Open the API Keys page, click Create API Key, and give the key a descriptive name. Copy the key when it is shown — Boson API keys use the format bai-xxxx.Store it securely and never commit it to source control. See Authentication for storage patterns and how requests are authenticated.
3

Claim your free trial credit

New accounts get $10 in free trial credit, but it is not added automatically — claim it from the banner on the API Keys page or in billing overview. No payment method is required.
Don’t skip this step. API calls from an account without claimed credit or a positive balance fail with a 429 insufficient_quota error. See Free trial credit.

Optional: set up payment and limits

When you’re ready to go beyond the trial credit, add a payment method and credits, turn on auto-reload so service never stops mid-project, and set a monthly spend cap if you want a hard ceiling.
