Create a sandbox key and call the real gateway against test data.
No sandbox session yet.
Broker integration demo — your account, raw JSON
Bring your own broker API keys, link your account, and pull your REAL portfolio through the unified rail — one contract for all 10 brokers. Keys stay in this page's memory only until connect; the vault stores them encrypted (AES-256) and they are hard-deleted on revoke. No keys handy? The sandbox buttons return deterministic demo data instantly.
Create a sandbox key above first — the demo calls the real gateway.
Each button is one GET on /v1/broker/* — the raw normalized JSON lands in the Response pane, identical shape for every broker.
