Frequently asked questions
What counts as an API call?
Each completed provider request executed through Alter's proxy counts as one API call. SDK management calls (creating sessions, listing grants, and resolving identity) do not count toward the allowance.
What happens when I hit my API call limit?
On the Free plan, additional API calls are blocked at the 10K limit. On Starter and Growth plans, you can exceed the included limit and overage charges of $0.50 per 1K additional calls apply automatically.
Can I upgrade or downgrade at any time?
Yes. Upgrades take effect immediately. Downgrades take effect at the start of the next billing cycle.
Do you offer annual billing?
Yes. Contact us at founders@alterauth.com for annual pricing with a discount.
What happens to custom limits when I change plans?
Custom limits negotiated for your organization are grandfathered: they are stored as per-organization overrides and survive upgrades and downgrades, so a plan change never silently revokes an exception you were granted. Removing an override is always a separate, explicit action.
What's included in the free tier?
The Free tier includes every platform feature except custom branding: OAuth, managed secrets, the full policy engine, and OIDC identity providers, with unlimited apps, connections, and team members, 10K API calls per month (no overage charges; usage pauses at the limit), and 30-day audit log retention. No credit card required.
