🤷‍ What is NexAPI?

The NexAPI library is a collection of APIs from many well-known cryptocurrency exchanges. It provides quick access to market data for storage, analysis, visualization, indicator development, algorithmic trading, strategy backtesting, bot programming, and related software engineering.

It is intended to be used by coders, developers, technically-skilled traders, data-scientists and financial analysts for building trading algorithms.

🔎 Usage

Binance Example

Example 1: REST API

package main

import (
	"context"
	"encoding/json"
	"fmt"

	bnspotmd "github.com/rluisr/nexapi/binance/spot/marketdata"
	bnspottypes "github.com/rluisr/nexapi/binance/spot/marketdata/types"
	bnspotutils "github.com/rluisr/nexapi/binance/spot/utils"
)

func main() {
	cli, err := bnspotmd.NewSpotMarketDataClient(&bnspotutils.SpotClientCfg{
		Debug:   true,
		BaseURL: bnspotutils.BaseURL,
	})
	if err != nil {
		panic(err)
	}

	orderbook, err := cli.GetOrderbook(context.TODO(), bnspottypes.GetOrderbookParams{
		Symbol: "BTCUSDT",
		Limit:  5,
	})
	if err != nil {
		panic(err)
	}

	limit := orderbook.Http.ApiRes.Header.Get("X-Mbx-Used-Weight-1m")

	fmt.Printf("Current used request weight: %v\n", limit)

	bytes, err := json.MarshalIndent(orderbook.Body, "", "\t")
	if err != nil {
		panic(err)
	}

	fmt.Println(string(bytes))
}

Example 2: Websocket

package main

import (
	"fmt"
	"time"

	spotws "github.com/rluisr/nexapi/binance/spot/websocketmarket"
	"github.com/rluisr/nexapi/binance/spot/websocketmarket/types"
)

func main() {
	cli, err := spotws.NewSpotMarketStreamClient(&spotws.SpotMarketStreamCfg{
		Debug:         true,
		BaseURL:       spotws.SpotMarketStreamBaseURL,
		AutoReconnect: true,
	})
	if err != nil {
		panic(err)
	}

	err = cli.Open()
	if err != nil {
		panic(err)
	}

	topic, err := cli.GetAggTradeTopic("btcusdt")
	if err != nil {
		panic(err)
	}

	cli.AddListener(topic, func(e any) {
		trade, ok := e.(*types.AggregateTrade)
		if !ok {
			return
		}

		fmt.Printf("Topic: %s, Symbol: %v, Price: %v, Quantity: %v, Time: %v\n",
			topic, trade.Symbol, trade.Price, trade.Quantity, trade.EventTime)
	})

	cli.Subscribe([]string{topic})

	time.Sleep(20 * time.Second)

	cli.Close()

	select {}
}
