What happens when I hit the Free plan limit?

Calls return 429 quota-exceeded until the next calendar month (UTC). Add a card to move to Pay as you go and keep going.

No. We serve public reference data and never accept patient information, so there's nothing to sign.

Are cached or repeated calls billed?

Yes, every served call counts, including repeats. Use ETags: a 304 Not Modified response still counts as a call but saves bandwidth.
