API Gateway came out with a cheaper variant (called HTTP APIs, admittedly a poor name) that is $1 per 300 million requests (114 requests per second for a month): https://aws.amazon.com/api-gateway/pricing/

You can also hook up an Application Load Balancer to Lambdas if that works for you: https://aws.amazon.com/elasticloadbalancing/pricing/

That's $1/million requests for the first 300m requests each month, not $1/300m requests.

It still increases the cost of running Lambda a whole lot, but that seems pretty reasonable for the projects I'm running.

You are correct, I misread this.
