When MetalpriceAPI might still be the right call
We don't pretend every team should pick us. If you've already integrated MetalpriceAPI, your traffic fits inside their free tier, and you don't need embeddable widgets 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 market data feed.
