I'm already a customer. Do I need Core?
If you're on the Scale or Enterprise plan, you already have access to the APIs—but they charge per result: each proposal, report, or receipt your AI generates costs you the platform price (~$2.50). With the Core membership, your software charges per API call: the same proposal costs you ~$1.50, and your first [5,000] calls (~100 proposals) are included.
I was about to cancel so I could develop my own software. What's the best option for me?
Don't rewrite the engine. With Core, you keep rates, configuration, data, and APIs, and your software works from day one.
