Official SDK Libraries

Official client libraries for Python, JavaScript, Go, and Rust. Simplify API integration with typed clients, automatic retry logic, and WebSocket support.

Python SDK

Package: smartmoney-api

Installation: pip install smartmoney-api

Repo: github.com/smartmoneyapi/python-client

Python

from smartmoney import SmartMoneyAPI

# Initialize client
client = SmartMoneyAPI(api_key="sk_live_abc123xyz789")

# Get whale positions
whales = client.whale_positions(symbol="BTCUSDT", limit=50)
for position in whales:
    print(f"{position.wallet_address}: {position.position_size} BTC @ {position.entry_price}")

# Get funding rates
funding = client.funding_rates(symbol="BTCUSDT", interval="4h", limit=24)

# Stream live updates
with client.stream_whale_positions(["BTCUSDT", "ETHUSDT"]) as stream:
    for update in stream:
        print(f"Position update: {update}")

Features

Async/await support (asyncio, aiohttp)
Automatic retry with exponential backoff
WebSocket streaming with auto-reconnect
Type hints and IDE autocomplete
Request logging and debugging

JavaScript SDK

Package: smartmoney-api

Installation: npm install smartmoney-api

Repo: github.com/smartmoneyapi/js-client

JavaScript

import { SmartMoneyAPI } from "smartmoney-api";

const client = new SmartMoneyAPI({
  apiKey: "sk_live_abc123xyz789"
});

// Get whale positions
const whales = await client.whalePositions({
  symbol: "BTCUSDT",
  limit: 50
});

whales.positions.forEach(pos => {
  console.log(`${pos.wallet_address}: ${pos.position_size} BTC`);
});

// Stream real-time updates
const stream = client.streamWhalePositions(["BTCUSDT", "ETHUSDT"]);
stream.on("data", (update) => {
  console.log("Position update:", update);
});
stream.on("error", (err) => {
  console.error("Stream error:", err);
});

Go SDK

Module: github.com/smartmoneyapi/go-client

Installation: go get github.com/smartmoneyapi/go-client

package main

import (
    "fmt"
    "github.com/smartmoneyapi/go-client"
)

func main() {
    // Create client
    client := smartmoney.NewClient("sk_live_abc123xyz789")

    // Get whale positions
    positions, err := client.WhalePositions(ctx, &smartmoney.WhalePositionsFilter{
        Symbol: "BTCUSDT",
        Limit:  50,
    })
    if err != nil {
        panic(err)
    }

    for _, pos := range positions {
        fmt.Printf("%s: %.2f BTC\n", pos.WalletAddress, pos.PositionSize)
    }
}

Rust SDK

Crate: smartmoney-api

Installation: cargo add smartmoney-api

Rust

use smartmoney_api::Client;

#[tokio::main]
async fn main() -> Result<(), Box> {
    let client = Client::new("sk_live_abc123xyz789");

    // Get whale positions
    let positions = client
        .whale_positions()
        .symbol("BTCUSDT")
        .limit(50)
        .send()
        .await?;

    for position in positions.iter() {
        println!(
            "{}: {} BTC @ {}",
            position.wallet_address,
            position.position_size,
            position.entry_price
        );
    }

    Ok(())
}

Common Patterns

Error Handling

All SDKs provide rich error types with automatic retry logic. Errors include status code, error code, and human-readable message.

Request Timeouts

Configurable request timeouts (default 30s). Set custom timeouts for long-running operations.

Rate Limit Handling

Automatic exponential backoff when hitting rate limits. Respects Retry-After header.
