Frequently asked questions
What counts as an API call?
Each request to /v1/check counts as one call, regardless of the response (supported or unsupported product).
Do unused calls roll over?
No. Included calls reset on your billing anniversary each month.
Can I change plans?
Yes — upgrade or downgrade at any time via your billing portal. Tier changes take effect immediately.
What happens when I hit my limit?
It depends on your tier. Free tier: further calls return HTTP 429 until your period resets — upgrade to continue. Starter and Pro: calls beyond your included allocation are billed automatically via Stripe at the overage rate. Your pipeline is never blocked.
How does overage billing work?
Starter and Pro tiers use Stripe Meter billing. Once you exceed your included calls, each additional call is charged at $0.002 (Starter) or $0.0008 (Pro). There is no cap — the API keeps working. You'll see the overage charge on your next invoice.
Will I get a warning before hitting my limit?
Yes. You'll receive an email when you've used 80% of your included calls for the month. Free users get a prompt to upgrade; Starter and Pro users are reminded that overage billing will kick in automatically.
Is there a trial period?
The free tier is permanent — no time limit. You can evaluate the full response schema and integrate before upgrading.
What products are supported?
Currently 20+ products including PostgreSQL, nginx, Redis, OpenSSH, Log4j, Apache HTTP Server, OpenSSL, curl, MySQL, MongoDB, Elasticsearch, and more. See the full list on the Products page. Coverage expands each quarter based on data quality and demand.
