Developer API

YieldScope Public API

One free, open JSON endpoint with our base APY rates and A–F safety grades across every tracked exchange. No key, no sign-up, CORS-open. Refreshed daily. Build on it — just attribute the data.

Endpoint

GET https://yieldscope.io/api/rates.json

What's inside

Per platform: name, slug, safety grade (A–F), criteria passed, jurisdiction, homepage, last_updated, and a rates[] list (asset, apy, type, lock_days). Plus a borrow map (cheapest CeFi/DeFi rate per asset).
