No account, card, premium plan, or upgrade nag. The core tool stays free.

Where does IndieOpenAPI's answer come from?

The answer follows OpenAPI Specification. The source stays named and linked beside the result it produced.

What happens to what I check?

Nothing you check becomes public inventory. The page uses cookieless analytics and stores no lookup history.
