What you integrate
One documented REST and WebSocket surface across asset classes and venues. Open accounts, move funds, place idempotent orders, stream quotes, fills and positions — on rails of a licensed operator, not a vendor-only API.
What you integrate
Same capabilities as on Embedded Investing and Brokerage Infrastructure — listed here for teams that start from the API.
Open client accounts via API. KYC stays inside your UI — document OCR, liveness and sanctions screening, white-labeled.
Connect your wallet, card or bank rail. Funds settle to the brokerage account.
Idempotent orders, deterministic IDs, event-sourced fills. Pre-trade risk and position limits run on our side.
Streaming quotes, order book, fills, your positions and P&L.
Equities, ETFs, bonds, FX, derivatives, Shariah instruments — one API. 14 connected markets.
Client statements, tax forms, regulator filings — generated and filed by us after you go live.
What clients see
Live quotes, charts and order tickets for stocks, crypto and ETFs. Ship our white-label web, iOS, Android and Telegram clients, or keep your own front-end and talk to the same REST and WebSocket surface.
Where it lands
Plug investing into an app you already own. No OMS required. MegaFon Tajikistan is live.

Same request shape as on Embedded Investing. Sandbox credentials are issued after a scoping call.

Move funds from your wallet to the account POST /v1/transfers { "account_id": "acc_01H...", "amount": 500, "currency": "USD" } POST /v1/orders { "account_id": "acc_01H...", "symbol": "AAPL", "side": "buy", "quantity": 1, "type": "market" }
Tell us the channel — bank app, telecom, white-label or Telegram — and the asset mix. Engineering will map the same REST and WebSocket surface.
