Report Card](https://goreportcard.com/badge/github.com/grinply/universal-crypto-api?style=flat-square)](https://goreportcard.com/report/github.com/grinply/universal-crypto-api)\n[![Software License](https://img.shields.io/badge/license-MIT-brightgreen.svg?style=flat-square)](/LICENSE.md)\n[![Go Reference](https://pkg.go.dev/badge/github.com/grinply/cryptoapi.svg)](https://pkg.go.dev/github.com/victorl2/kate-backtester)\n# CryptoAPI\n\n**CryptoAPI** is a interface in Golang that aims to abstract the connection with [cryptocurrency exchanges](https://coinmarketcap.com/rankings/exchanges/). The API supports both **spot** and **derivative** markets. \n\n\n\n# Usage\n\nFirst you need to install the **CryptoAPI** in your project, run `go get github.com/grinply/cryptoapi` to add the dependency.\n\nThree main interfaces are provided with abstractions to access exchanges in a unified way. [**OrderConnector**](pkg/trade/order_connector.go) allows users to execute [**orders**](https://www.tradingpedia.com/bitcoin-guide/what-types-of-orders-to-trade-bitcoin-on-crypto-exchanges-are-there/) and access private information _(such as asset balances)_:\n\n```go\npackage trade\n\ntype OrderConnector interface {\n\tFindOrderByID(tradingPair CurrencyPair, orderID string) (Order, error)\n\n\tOpenOrders(tradingPair CurrencyPair) ([]Order, error)\n\n\tNewOpenOrder(orderToOpen Order) (string, error)\n\n\tCancelOrder(tradingPair CurrencyPair, orderID string) error\n\n\tCancelOpenOrders(tradingPair CurrencyPair) error\n}\n\n```\n\nThe [**PriceConnector**](pkg/trade/price_connector.go) provides access to **price data** without the need for authentication:\n\n```go\n\ntype PriceConnector interface {\n\tLatestPrice(tradingPair CurrencyPair) (string, error)\n\n\tCandles(tradingPair CurrencyPair, qty int, interval CandleInterval) \n        ([]CandleStick, error)\n\n\tPriceFeed(tradingPair CurrencyPair) \u003c-chan CandleStick\n}\n```\n\nThe [**InfoConnector**](pkg/trade/info_connector.go) provides access to **general exchange information** about what is avaliable\n\n```go\ntype InfoConnector interface {\n\tTradingPairs() ([]CurrencyPair, error)\n\n\tTradingRules(tradingPair CurrencyPair) (Rule, error)\n\n\tCoinsBalance() ([]Asset, error)\n}\n```\n\nTo make use of both connectors you just need to provide the required information to a function, a implementation for the requested exchange will be provided for your use:\n\n```go\npackage main\n\nimport (\n\t\"fmt\"\n\t\"github.com/grinply/cryptoapi\"\n)\n\nfunc main() {\n    //replace the keys  with your own values.\n    var apiKey = \"my_api_key\"\n    var secretKey = \"my_secret_key\"\n    var exchange = \"binance\"\n\n\tconnector, err := cryptoapi.OrderConnector(exchange, apiKey, secretKey, false)\n\n\tif err != nil {\n\t\tfmt.Printf(\"Connector failed with the provided credentials.%v\\n\", err.Error())\n\t\treturn\n\t}\n\n\t//Print the amount of each asset present in the exchange wallet\n\tif assetsBalance, err := connector.WalletBalances(); err == nil {\n\t\tfor _, asset := range assetsBalance {\n\t\t\tfmt.Printf(\"%s - available: %s | locked: %s\\n\", \n\t\t\t\tasset.Name, asset.FreeQty, asset.LockedQty)\n\t\t}\n\t}\n}\n```\n\n[_More info about **examples** using the CryptoAPI_](docs/)\n","project_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fgrinply%2Fcryptoapi","html_url":"https://awesome.ecosyste.ms/projects/github.com%2Fgrinply%2Fcryptoapi","lists_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fgrinply%2Fcryptoapi/lists"}
