Buy Pro on the Pricing page. Agents can buy either pass themselves: see Passes for agents.
What stays free
Every check shows every warning, with or without a pass: Svalin never hides “don’t pay this address” behind a paywall.
When limits reset
Free calls and a Pro pass’s daily calls come back at 00:00 UTC. Each answer from a free route carries an X-Free-Remaining header that says how many are left today.
What counts as a call
A call that fails is never charged and does not count against a pass. Bad input is rejected before any payment. See Errors.
