I’ve never used API gateway outside of quick prototype tests to access lambda. $750 per month doesn’t sound like a lot of money if you have 225 million requests per month. A free API is probably an exception but I do realize why that would too expensive for your use case.

225e6 requests/month is about 80 requests/second. That's a very low rate for a gateway.

You’re assuming an even distribution of requests, but that’s not usually the case. It could be several multiples of that at peak.
