Get an sk_test_ API key instantly, with no account and no human. A test key never sends a real SMS and never spends credits, so a whole integration can be built and verified with it. Pass it as api_key to send_message and get_message, and keep it in the application's configuration (for example NOTIFY_API_KEY), never in source code. The result also has a claim_url for a human: opening it lets them sign in and take over the project. Anyone who opens it, signs in and confirms becomes the owner: give it only to the person who will own the project, and do not paste it into shared logs or tickets. Real SMS need an sk_live_ key that the human creates on the dashboard (https://n0t1fy.dev/dashboard). Limited to a few keys per minute and per day for each address: reuse a key you already have.
