Trying to understand why a developer would like to call an API to generate code rather than use a coding AI assistant within their editor? Genuinely curious.
I'm not yet committed to this because I know that many (most?) people cannot express their intentions in plain English concisely and precisely enough to be implemented as an algorithm. As my first formal instructor of programming taught me, a lot of programming just that: thinking through what one wants, with sufficient rigor. Support for such a feature could be a nightmare, making it more trouble than it is worth. However, I may offer it as an experiment. It might work well enough to, say, draft Google Sheets formulas that power users could tweak.
