There's no fixed requests-per-second limit for registered API keys — your real constraint is the monthly credit allowance. Once it's exhausted, you'll get `429` responses until your next billing cycle (or you can enable pay-as-you-go). We do throttle abusive or unregistered local-dev traffic to prevent abuse. Expecting high, sustained volume? [Email us](mailto:support@stadiamaps.com) and we'll make sure your use case is covered.
