ZHC API Services

DNS and robots checking APIs from Zero Human Company. Free tier requires an account; Pro adds higher daily limits.

Pro stays active for 30 days per ZHC payment. Your existing API token keeps working; limits increase automatically after PayPal confirms payment (you are redirected to PayPal — no payment details are shown on this page).
