Free key
No account, no email, no dashboard
100 calls a day without a key · 1,000 a day with this free key · 50,000 a day on Agent Pro. Send it as the x-api-key header on any /api/public/* request.
Planning to upgrade later?
This key is anonymous: it is not attached to any account, so it stays at 1,000 calls a day even if you subscribe afterwards. If you expect to go to Agent Pro (50,000 calls a day), create your key while signed in on /keys — account keys switch to 50,000 automatically the moment the subscription is active, with nothing to recreate.
