Get an API key
100 calls per day. The key is shown once. Screwtape stores a SHA-256 hash, a short prefix, your email, and your name. Nothing else is required, and Stripe is not required.
Your key
This tab keeps the key in sessionStorage so you can check usage. It is not a cookie, and it is not sent anywhere except back to this API.
Prepaid packs
Starter is $30 for 10,000 calls. Builder is $100 for 50,000 calls. Checkout uses Stripe test mode and adds credits only after the webhook sees a paid test session.
