This guide takes you from zero to your first order. You will read public market data (no credentials), sign in with your wallet, move collateral into a venue, and place a trade. All requests go through the API gateway, referred to here as {BASE_URL}.
Prices and sizes are decimal strings. Send and parse them as strings to keep full precision.

​
1. Read public market data

No authentication is needed for market data. List the linear markets and pull a book snapshot. 
# list perp / futures / spot markets
curl -s "{BASE_URL}/perps/markets"

# order book snapshot for one market
curl -s "{BASE_URL}/perps/orderbook/BTC-PERP?depth=10"

# 24h ticker: mark, change, volume, open interest, funding
curl -s "{BASE_URL}/perps/market-stats?marketId=BTC-PERP"
Example market-stats response: 
{
  "marketId": "BTC-PERP",
  "baseSymbol": "BTC",
  "markPrice": "68210.5",
  "change24hPct": "1.42",
  "volume24hUsd": "18422100",
  "openInterestUsd": "9231000",
  "funding1hPct": "0.0021"
}
For live values, subscribe to the SSE stream {BASE_URL}/perps/book-stream?marketId=BTC-PERP instead of polling — it pushes a snapshot then incremental updates.

​
2. Sign in with your wallet

Open a session with SIWE. Request a nonce, sign the message in your wallet, then verify. See Authentication for the full flow. 
NONCE=$(curl -s -X POST {BASE_URL}/auth/nonce \
  -H 'Content-Type: application/json' \
  -d '{"walletAddress":"0xabc..."}' | jq -r .nonce)

# build + sign the SIWE message with $NONCE → $MSG, $SIG
curl -s -c cookies.txt -X POST {BASE_URL}/auth/siwe \
  -H 'Content-Type: application/json' \
  -d "{\"message\":\"$MSG\",\"signature\":\"$SIG\"}"
The -c cookies.txt jar now holds your session cookie; pass -b cookies.txt on authenticated calls.

​
3. Fund a venue

Deposits land in your wallet bucket. Move collateral into the venue you want to trade — here, perps.
1

Check your balances

curl -s -b cookies.txt {BASE_URL}/wallet/balance

{ "walletBalance": "2000.00", "perpsBalance": "0", "optionsBalance": "0", "pendingWithdrawalTotal": "0" }
2

Transfer wallet → perps

curl -s -b cookies.txt -X POST {BASE_URL}/wallet/transfer \
  -H 'Content-Type: application/json' \
  -d '{"from":"wallet","to":"perps","amount":"500"}'
Transfers are atomic. Move funds back to wallet before withdrawing.

​
4. Preview, then place your first order

Always dry-run first. preview returns your notional, estimated fee, fee role, your volume tier, and whether the order passes the margin check — with no side effects. 
# dry-run
curl -s -b cookies.txt -X POST {BASE_URL}/perps/orders/preview \
  -H 'Content-Type: application/json' \
  -d '{"marketId":"BTC-PERP","side":"buy","type":"limit","price":"68000","quantity":"0.05"}'

# place a post-only limit order
curl -s -b cookies.txt -X POST {BASE_URL}/perps/orders \
  -H 'Content-Type: application/json' \
  -d '{"marketId":"BTC-PERP","side":"buy","type":"limit","price":"68000","quantity":"0.05","timeInForce":"gtc","postOnly":true,"clientOrderId":"my-first-order"}'
Use clientOrderId for idempotent client-side tracking. postOnly keeps you on the maker side (the order is rejected if it would take liquidity), and reduceOnly prevents an order from increasing your position.

​
5. Watch your orders, positions, and fills

curl -s -b cookies.txt "{BASE_URL}/perps/orders/open"
curl -s -b cookies.txt "{BASE_URL}/perps/positions"
curl -s -b cookies.txt "{BASE_URL}/perps/trades"
To exit, cancel resting orders or close the position: 
curl -s -b cookies.txt -X POST {BASE_URL}/perps/orders/cancel-all \
  -H 'Content-Type: application/json' -d '{"marketId":"BTC-PERP"}'

curl -s -b cookies.txt -X POST {BASE_URL}/perps/positions/close \
  -H 'Content-Type: application/json' -d '{"marketId":"BTC-PERP"}'
