When GoldAPI.io might still be the right call
If you've already integrated GoldAPI.io, your traffic fits inside their free tier, and you don't need embeddable widgets or 180+ currencies, there's no urgent reason to migrate. Metal Sentinel makes more sense as your needs grow: more metals, more currencies, embeddable widgets, transparent pricing, or a primary market data feed.
