gobcy

A Go wrapper for the BlockCypher API. Targeting support for Bitcoin (main and testnet3) and BlockCypher's internal testnet, but others (Litecoin, Dogecoin) should work too. The wrapper works also for some query for Ethereum but the compatibility is not fully guaranteed.

Configuration

Import the package like so:

import "github.com/blockcypher/gobcy"

Then initiate an API struct with your credentials:

//explicitly
bc := gobcy.API{}
bc.Token = "your-api-token-here"
bc.Coin = "btc" //options: "btc","bcy","ltc","doge","eth"
bc.Chain = "main" //depending on coin: "main","test3","test"

//using a struct literal
bc := gobcy.API{"your-api-token-here","btc","main"}

//query away
fmt.Println(bc.GetChain())
fmt.Println(bc.GetBlock(300000,"",nil))

Usage

Check the "types.go" file for information on the return types. Almost all API calls are supported, with a few dropped to reduce complexity. If an API call supports URL parameters, it will likely appear as a params map[string]string variable in the API method. You can check the docs for supported URL flags.

Speaking of API docs, you can check out BlockCypher's documentation here. We've also heavily commented the code following Golang convention, so you might also find the GoDoc quite useful. The gobcy_test.go file also shows most of the API calls in action.

Testing

The aforementioned gobcy_test.go file contains a number of tests to ensure the wrapper is functioning properly. If you run it yourself, you'll have to insert a valid API token; you may also want to generate a new token, as the test POSTs and DELETEs WebHooks and Payment Forwarding requests.
