Congrats on the launch! Over the past 6 months or so I’ve been intermittently working on building pretty much exactly the same thing, but with a lot of procrastinating on fiddling with the internals rather than just putting something out there. Your API-first approach is a clever way to get around the desire to keep fiddling around with the page design!
I find that plain text is a very effective anti-procrastination tool. That's why the "API" was actually text-first. Limiting your options can be very liberating.
