Multi-Asset Support
Unified API across crypto, equities, FX, and derivatives
The broker provides a single API surface for trading across multiple asset classes. Symbol format and market data routing are handled automatically based on the asset type.
Symbol Format
The broker distinguishes asset classes by symbol format:
| Format | Asset Class | Examples | Routing |
|---|---|---|---|
Contains / | Crypto pair | BTC/USD, ETH/BTC | Crypto exchanges (Coinbase, Binance, Kraken, etc.) |
| Plain uppercase | US equity | AAPL, TSLA, SPY | Broker-dealers (Alpaca, IBKR, Tradier) |
| Three-letter pair | FX | EUR/USD, GBP/JPY | FX desks (CurrencyCloud, LMAX) |
When you request a route or place a smart order, the router queries all providers that support the asset class and returns only those with active quotes.
Asset Classes by Provider
| Asset Class | Providers |
|---|---|
| US Equities | Alpaca, Interactive Brokers, Tradier |
| Crypto Spot | Coinbase, Binance, Kraken, Gemini, SFOX, BitGo, LMAX |
| Options | Interactive Brokers, Tradier |
| Futures | Interactive Brokers |
| FX | CurrencyCloud, LMAX, Interactive Brokers |
| Commodities/Metals | LMAX, Interactive Brokers |
| Stablecoins | Circle (USDC/EURC mint/burn) |
Market Data Routing
Market data endpoints are provider-scoped: /v1/market/{provider}/snapshot/{symbol}. This lets you query a specific provider's view of an asset.
For cross-venue comparison, use the consolidated endpoints:
GET /v1/bbo/{symbol}-- Best bid/offer across all venuesGET /v1/bbo/{symbol}/{quote}-- BBO for a specific pairGET /v1/stream-- SSE stream of real-time consolidated tickers
The consolidated BBO response includes provider attribution, showing which venue has the best bid and which has the best ask.
Aggregated Asset List
GET /v1/assets returns all tradable assets deduplicated across providers. Each asset includes the list of providers that support it:
{
"symbol": "BTC/USD",
"name": "Bitcoin",
"class": "crypto",
"providers": ["binance", "coinbase", "kraken", "sfox"]
}This is useful for building UIs that show which venues are available for a given instrument.
