€19 for 1,000 units. Never expire, combinable with any plan, no automatic charges.

No — the quota included in your plan is per calendar month and doesn't roll over. Every month starts fresh with 5,000 units (the yearly plan is also 5,000/month, not an annual pool). Exception: separately purchased credits never expire and stay even after cancellation.
The API responds with 402 and a clear error message. Nothing is charged automatically — you decide whether to upgrade or buy credits.
Yes — the yearly plan includes two months free (€490 instead of €588). Switch anytime in the console.
You can cancel the monthly plan anytime, effective at the end of the billing month. The yearly plan runs for 12 months; you can turn off auto-renewal anytime — it then ends when the paid term expires, with no pro-rata refund. Credits never expire and are non-refundable.

Every report carries an engine version and a calendar-based ruleset version (e.g. 2026.07); /v1/health and the WASM bh_version() expose both. The ruleset bumps whenever rules are added, changed or tightened — log it alongside your result and any outcome stays reproducible.
