Credits

Successful predictions consume either paid credits or free-tier allowance. Manage balance and purchase credit packs in the dashboard.

How billing works

1. If your account has a paid credit balance, successful calls debit credits first.
2. When the paid balance is 0, successful calls use the free tier (if remaining).
3. When both are exhausted, billed endpoints return 402.

Failed requests (validation errors, unknown measurements, out-of-range lookups, auth failures) do not consume credits or free-tier calls.

Free tier

• 10 successful calls per rolling 24-hour window
• Free-tier success responses may include remaining_free_calls
• When exhausted, the error includes resets_at so you know when the window refreshes
