New Boson AI accounts get $10 in free trial credit to use on any Boson API — Higgs Realtime, Higgs TTS 3, and Higgs Avatar. No payment method is required.

​
Claim your credit

Trial credit is not added to your balance automatically. Claim it once from either: The claim banner in your workspace shows the exact amount available to your account.
Until you claim, your account has no active billing balance and API calls fail with a 429 insufficient_quota error (Realtime sessions receive an error event and close with code 4429). See Common error types.

​
Scope and expiry

  • Trial credit works on all Boson APIs — there is no per-product restriction.
  • Trial credit expires 12 months after you claim it.
  • Usage draws down your balance at the standard pricing rates.

​
When it runs out

When your balance reaches zero, requests are refused with the same insufficient_quota error until you add credits. Your account and API keys are unaffected — service resumes once you add credits. To avoid interruption, add a payment method and turn on auto-reload before the credit runs out. You can watch your balance and spend anytime in billing overview.
