200 calls a day, for your email.

Without a key the API allows 25 calls a day for each IP address. A free key gives 200 calls a day, resetting at 00:00 UTC, with no card and no account. Your key appears on this page at once. One key per address. We send one note three days later with what it has used. Nothing else. Free use is for one person: your own projects or your studies. Production, team and commercial use need a paid plan.
