State the use case
One concrete integration use case defines what the API needs to support.

YOUR INPUTS
Build your result
Complete every field. The result updates only when you choose Calculate.
How it works
List endpoints
5 or fewer endpoints is a lean starting surface.
Choose auth
API keys ship faster than OAuth for a first integration partner.

Frequently asked questions
Should I version my API from the start?
Yes — even with one consumer, versioning (e.g. /v1/) is far easier to add now than later.
Is API key auth secure enough?
For a first integration partner, yes, if paired with HTTPS and reasonable key rotation practices.
When do I need rate limiting?
Add it once you have real usage patterns to base limits on, or before opening the API more broadly.
