Getting a key
Keys are issued by our team. Email [email protected] with a short note on what you are building and your expected request volume. Starter plans include a 7-day free trial.
Keeping your key safe
- Treat the key like a password. Send it only in the request header, never in a URL.
- Use separate keys per environment if your plan includes them, so a leaked staging key never touches production.
- If a key is exposed, write to us and we will rotate it.
