If you're building something that needs to interact with Binance's earning products, this handles the API calls for you. It works with Binance's Simple Earn endpoints, which let you subscribe to flexible or locked savings products, check balances, and manage redemptions. You'll need your API key and secret since these are authenticated endpoints. The skill returns everything in JSON, so it's straightforward to parse. It's part of Binance's official skills hub, which passed most security audits except Snyk. Honestly, this is one of those utilities that saves you from reading Binance API docs if you just want to let users earn yield through your app.
