What this key can trade right now

GEThttps://app.skylit.ai/api/nexus/v1/trading/capabilities

The asset classes, order types, futures contracts and futures accounts this key can trade right now, plus your per-key limits. Call it when your bot starts, so it asks instead of guessing.

Options and stocks always list market as their only order type. The futures block is there only when your account has futures paper trading. When it doesn't, the futures entry under assetClasses says why. The first call creates your futures practice account if you don't have one yet, as Nexus does when you open the futures ticket.

Authorization

Authorization: Bearer <your API key>

Required. A missing header returns 401; an invalid, revoked or expired key returns 403.
