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. Limits 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?
Further calls return HTTP 429. Your integration can catch this and log it or pause the pipeline. No data is lost.
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?
V1 covers PostgreSQL, nginx, Redis, OpenSSH, Log4j, Apache HTTP Server, OpenSSL, and curl. More products ship post-launch based on demand.
