Official Blockfrost SDK Client

Build status Go report card GoDoc

Getting started

To use this SDK, you first need to log in to blockfrost.io, create your project and retrieve the API token.


Installation

blockfrost-go can be installed through go get

$ go get https://github.com/blockfrost/blockfrost-go

Usage

Cardano API
package main

import (
	"context"
	"fmt"
	"log"

	"github.com/blockfrost/blockfrost-go"
)

func main() {
	api, err := blockfrost.NewAPIClient(
		blockfrost.APIClientOptions{
            ProjectID: "YOUR_PROJECT_ID_HERE", // Exclude to load from env:BLOCKFROST_PROJECT_ID
        },
	)
	if err != nil {
		log.Fatal(err)
	}

	info, err := api.Info(context.TODO())
	if err != nil {
		log.Fatal(err)
	}

	fmt.Printf("API Info:\n\tUrl: %s\n\tVersion: %s", info.Url, info.Version)
}
IPFS
package main

import (
	"context"
	"flag"
	"fmt"
	"log"

	"github.com/blockfrost/blockfrost-go"
)

var (
	fp = flag.String("file", "", "Path to file")
)

func main() {
	flag.Parse()
	// Load project_id from env:BLOCKFROST_IPFS_PROJECT_ID
	ipfs := blockfrost.NewIPFSClient(blockfrost.IPFSClientOptions{})

	ipo, err := ipfs.Add(context.TODO(), *fp)
	if err != nil {
		log.Fatal(err)
	}

	fmt.Printf("IPFS Object: %+v\n", ipo)

	// Pin item to avoid being garbage collected.
	pin, err := ipfs.Pin(context.TODO(), ipo.IPFSHash)
	if err != nil {
		log.Fatal(err)
	}
	fmt.Printf("Pin: %+v", pin)
}

More examples of usage can be found in example folder.
