Supported Coins

Alpaca supports over 20+ unique crypto assets across 56 trading pairs. Current trading pairs are based on BTC, USD, USDT and USDC) with more assets and trading pairs coming soon.

To query all available crypto assets and pairs you can you use the following API call:

curl --request GET 'https://api.alpaca.markets/v2/assets?asset_class=crypto' \
--header 'Apca-Api-Key-Id: <KEY>' \
--header 'Apca-Api-Secret-Key: <SECRET>'

Below is a sample trading pair object composed of two assets, BTC and USD.

{
  "id": "276e2673-764b-4ab6-a611-caf665ca6340",
  "class": "crypto",
  "exchange": "ALPACA",
  "symbol": "BTC/USD",

  "fractionable": true,
  "min_order_size": "0.0001",
  "min_trade_increment": "0.0001",
  "price_increment": "1"
}

Note that symbology for trading pairs has changed from our previous format, where BTC/USD was previously referred to as BTCUSD. Our API has made proper changes to support the legacy convention as well for backwards compatibility.

Transferring Crypto

Crypto Fees

While Alpaca stock trading remains commission-free, crypto trading includes a small fee per trade dependent on your executed volume and order type. Any market or exchange consists of two parties, buyers and sellers. When you place an order to buy crypto on the Alpaca Exchange, there is someone else on the other side of the trade selling what you want to buy. The seller's posted order on the order book is providing liquidity to the exchange and allows for the trade to take place. Note, that both buyers and sellers can be makers or takers depending on the order entered and current quote of the coin. A maker is someone who adds liquidity, and the order gets placed on the order book. A Taker on the other hand removes the liquidity by placing a market or marketable limit order which executes against posted orders.

See the below table with volume-tiered fee pricing:

Tier30D Trading Volume (USD)MakerTaker
10 - 100,00015 bps25 bps
2100,000 - 500,00012 bps22 bps
3500,000 - 1,000,00010 bps20 bps
41,000,000 - 10,000,0008 bps18 bps
510,000,000 - 25,000,0005 bps15 bps
625,000,000 - 50,000,0002 bps13 bps
750,000,000 - 100,000,0002 bps12 bps
8100,000,000+0 bps10 bps

The crypto fee will be charged on the credited crypto asset/fiat (what you receive) per trade. Some examples,

  • Buy ETH/BTC, you receive ETH, the fee is denominated in ETH
  • Sell ETH/BTC, you receive BTC, the fee is denominated in BTC
  • Buy ETH/USD, you receive ETH, the fee is denominated in ETH
  • Sell ETH/USD, you receive USD, the fee is denominated in USD

To get the fees incurred from crypto trading you can use Activities API to query activity_type by CFEE or FEE. See below example of CFEE object:

{
    "id": "20220812000000000::53be51ba-46f9-43de-b81f-576f241dc680",
    "activity_type": "CFEE",
    "date": "2022-08-12",
    "net_amount": "0",
    "description": "Coin Pair Transaction Fee (Non USD)",
    "symbol": "ETHUSD",
    "qty": "-0.000195",
    "price": "1884.5",
    "status": "executed"
}

Fees are currently calculated and posted end of day. If you query on same day of trade you might not get results. We will be providing an update for fee posting to be real-time in the near future.

Margin and Short Selling

Cryptocurrencies cannot be bought on margin. This means that you cannot use leverage to buy them and orders are evaluated against non_marginable_buying_power.

Cryptocurrencies can not be sold short.

Trading Hours

Crypto trading is offered for 24 hours everyday and your orders will be executed throughout the day.

Trading Limits

Currently, an order (buy or sell) must not exceed $200k in notional. This is per an order.
