Quick Start

curl
# Public: 24h ticker for a coin (no auth)
curl "/market/data/quotations/coin?coin=btc"

# Authenticated: log in and capture the JWT from data.Authorization
TOKEN=$(curl -s -X POST /uc/v2/login \
  -d "[email protected]&password=secret" \
  | jq -r .data.Authorization)

# Place a spot LIMIT buy — type=0 limit, type=1 market, direction=0 BUY, 1 SELL
curl -X POST "/tx/spot/add" \
  -H "Authorization: $TOKEN" \
  -d "symbol=BTC/USDT&direction=0&type=0&price=74000&amount=0.001"

# Spot wallet balances
curl -H "Authorization: $TOKEN" \
  "/uc/asset/spot-wallets"

# With an API key instead of a login token, send X-API-KEY / X-API-TIMESTAMP /
# X-API-SIGNATURE and sign the path WITHOUT /uc or /tx (/asset/spot-wallets).
# Full signing reference + Postman script: /developers#signing
