hCaptcha and AI agents.
hCaptcha is a check a site puts on a form, most often the sign-up form. Each site decides where it shows.
Most stops reflect each site's own settings, not the vendor's defaults.

What an owner can change.
Check the Web Bot Auth signature on the sign-up request (the agent's key directory is public) and skip hCaptcha for signed agents; or offer a documented sign-up API with email verification.
