title: Sync Client
description: AgentExchangeClient — synchronous Python client with 37 methods
---

`AgentExchangeClient` is a synchronous REST client built on `httpx`. It is thread-safe and can be shared across multiple tools in the same process. All responses are deserialized into frozen dataclasses with `Decimal` precision for monetary fields.

## Import and Construction

```python
from agentexchange import AgentExchangeClient

client = AgentExchangeClient(
    api_key="ak_live_...",
    api_secret="sk_live_...",
    base_url="http://localhost:8000",  # default
    timeout=30.0,                      # default
)

# Or use as a context manager for automatic cleanup
with AgentExchangeClient(api_key="...", api_secret="...") as client:
    price = client.get_price("BTCUSDT")
```

Always call `client.close()` when you are done, or use it as a context manager.

---

## Market Data (6 methods)

### `get_price(symbol)`

Fetch the current price for one trading pair. Price is sourced from Redis (sub-millisecond) and updated tick-by-tick from Binance.

```python
price = client.get_price("BTCUSDT")
# price.symbol    → "BTCUSDT"
# price.price     → Decimal("64521.30")
# price.timestamp → datetime(...)
```

**Returns:** `Price` dataclass

---

### `get_all_prices()`

Fetch current prices for all 600+ active pairs in a single call. Use this when scanning multiple coins — never loop `get_price`.

```python
prices = client.get_all_prices()
for p in prices:
    print(f"{p.symbol}: {p.price}")
```

**Returns:** `list[Price]`

---

### `get_candles(symbol, interval, limit=100)`

Fetch historical OHLCV candles for technical analysis.

```python
candles = client.get_candles(
    symbol="ETHUSDT",
    interval="1h",   # 1m, 5m, 15m, 1h, 4h, 1d
    limit=24,
)
for c in candles:
    print(f"{c.open_time}  O:{c.open}  H:{c.high}  L:{c.low}  C:{c.close}  V:{c.volume}")
```

**Returns:** `list[Candle]`

---

### `get_ticker(symbol)`

Fetch 24-hour ticker statistics: open, high, low, close, volume, and percentage change.

```python
ticker = client.get_ticker("SOLUSDT")
print(f"24h change: {ticker.change_pct}%")
print(f"Volume: {ticker.volume}")
```

**Returns:** `Ticker` dataclass

---

### `get_recent_trades(symbol)`

Fetch recent public trades for a symbol.

```python
trades = client.get_recent_trades("BTCUSDT")
```

**Returns:** `list[Trade]`

---

### `get_orderbook(symbol, depth=20)`

Fetch order book bids and asks. Use before large orders to estimate slippage.

```python
ob = client.get_orderbook("BTCUSDT", depth=10)
best_bid = ob.bids[0]  # [price, quantity]
best_ask = ob.asks[0]
print(f"Spread: {best_ask[0] - best_bid[0]}")
```

**Returns:** Object with `.bids` and `.asks` lists of `[Decimal, Decimal]` pairs

---

## Trading (9 methods)

> **Info:**
> Always call `get_balance()` before placing any order, and `get_price()` to verify the current price. After opening a new position, immediately place a stop-loss order.

### `place_market_order(symbol, side, quantity)`

Place a market order that fills immediately at the current live price. A small slippage factor is applied to simulate real market conditions.

```python
from decimal import Decimal

order = client.place_market_order(
    symbol="BTCUSDT",
    side="buy",           # "buy" or "sell"
    quantity=Decimal("0.01"),
)
print(f"Order: {order.order_id}  Status: {order.status}")
print(f"Filled at: ${order.executed_price}  Fee: ${order.fee}")
print(f"Slippage: {order.slippage_pct}%")
```

**Returns:** `Order` dataclass

---

### `place_limit_order(symbol, side, quantity, price)`

    symbol="BTCUSDT",
    side="buy",
    quantity=Decimal("0.01"),
    price=Decimal("62000.00"),
)
# order.status → "pending" until the price is reached
```

**Returns:** `Order` dataclass

---

### `place_stop_loss(symbol, side, quantity, trigger_price)`

Place a stop-loss order that triggers when the market reaches `trigger_price`.

```python
# Protect a long BTC position with a stop at $61,000
stop = client.place_stop_loss(
    symbol="BTCUSDT",
    side="sell",
    quantity=Decimal("0.01"),
    trigger_price=Decimal("61000.00"),
)
```

**Returns:** `Order` dataclass

    symbol="BTCUSDT",
    side="sell",
    quantity=Decimal("0.01"),
    trigger_price=Decimal("70000.00"),

```

**Returns:** `list[Order]`

---

### `cancel_order(order_id)`

```python
client.cancel_order("660e8400-e29b-41d4-a716-446655440001")
