Markets
GET /v1/{chain}/markets lists every pair with everything you need before placing an order:
GET /v1/{chain}/markets/{symbol} returns one market. Write the symbol as BTC-USD or BTC%2FUSD in the path.
Prices
GET /v1/{chain}/prices returns the mark and index price of every market. Mark is the execution price (spot plus skew for core crypto, futures for volatile crypto); index is the price liquidations use. They differ on volatile crypto pairs and are equal elsewhere. Updates arrive every 25 ms on the prices WebSocket channel.
Order book
GET /v1/{chain}/markets/{symbol}/book?levels=20
gTrade has no resting order book: execution goes through shared vault liquidity with deterministic price impact. The endpoint returns the virtual order book derived from the on-chain depth bands: each level is the liquidity available at that price offset, exactly what the trading interface displays.
size is in base asset, sizeUsd in USD, cumulativeUsd the depth from the mark to that level. Bids are ordered from the best (highest) price, asks from the best (lowest).
Candles
GET /v1/{chain}/markets/{symbol}/candles?interval=1h&from=1700000000000&to=1700086400000
Intervals: 1m, 5m, 15m, 30m, 1h, 4h, 1d. from and to are epoch milliseconds. Candles are mark-price OHLC; there is no volume on a synthetic book. The candles WebSocket channel streams the live candle.
Recent trades
GET /v1/{chain}/markets/{symbol}/trades?limit=100 returns the last executed trades on the market (opens, closes, liquidations), newest first, with price, sizeUsd, side, action, timestamp and txHash.
Funding
GET /v1/{chain}/markets/{symbol}/funding returns the current rates:
Funding on gTrade is velocity-based: the rate drifts with the skew instead of resetting every eight hours. Read the rate again before assuming it is constant.
