When GoldAPI.io might still be the right call
We don't pretend every team should pick us. If you've already integrated GoldAPI.io, your traffic fits inside their free tier, and you don't need widgets, a WordPress plugin, or 180+ currencies, there's no urgent reason to migrate. The case for Metal Sentinel gets stronger the more of these you need: more metals, more currencies, embeddable surfaces, transparent pricing, and a primary Kitco-sourced feed.
