Quickstart

This quickstart guide will help you set up and make calls on the IPFS network using the Infura endpoints.

info

To access the IPFS network through Infura, you'll need to add a billing card to your account, even if you're using a free account. Refer to the billing details for more information.

Prerequisites​

Before you begin, ensure you have a valid API key and API key secret.

Make calls​

cURL​

cURL generates the auth header and encodes your credentials behind the scenes.

Include the -u flag with the authentication information.

curl -X POST -F file=@myfile -u "<API_KEY>:<API_KEY_SECRET>" "https://ipfs.infura.io:5001/api/v0/add"

JavaScript​

Wrap JavaScript calls to IPFS with the Infura Authorization header.

xhr.setRequestHeader("Authorization", "Basic " + btoa(<API_KEY> + ":" + <API_KEY_SECRET>));

NodeJS​

Change the <API_KEY> and <API_KEY_SECRET> in the NodeJS example code below.

Save the following script to a file, e.g. index.js.

const https = require("https");

const projectId = "<API_KEY>";
const projectSecret = "<API_KEY_SECRET>";

const options = {
  host: "ipfs.infura.io",
  port: 5001,
  path: "/api/v0/pin/add?arg=QmeGAVddnBSnKc1DLE7DLV9uuTqo5F7QbaveTjr45JUdQn",
  method: "POST",
  auth: projectId + ":" + projectSecret,
};

let req = https.request(options, (res) => {
  let body = "";
  res.on("data", function (chunk) {
    body += chunk;
  });
  res.on("end", function () {
    console.log(body);
  });
});
req.end();

In a terminal window, run the script with node index.js

Output something like:

{"Pins":["QmeGAVddnBSnKc1DLE7DLV9uuTqo5F7QbaveTjr45JUdQn"]}

Python​

Change the projectId and projectSecret in the Python example code below.

Save the following script to a file, e.g. index.py.

import requests

projectId = "<API_KEY>"
projectSecret = "<API_KEY_SECRET>"
endpoint = "https://ipfs.infura.io:5001"

### CREATE AN ARRAY OF TEST FILES ###
files = {
    'file': 'myNFT.png'
}

### ADD FILE TO IPFS AND SAVE THE HASH ###
response1 = requests.post(endpoint + '/api/v0/add', files=files, auth=(projectId, projectSecret))
print(response1)
hash = response1.text.split(",")[1].split(":")[1].replace('"','')
print(hash)

### READ FILE WITH HASH ###
params = {
    'arg': hash
}
response2 = requests.post(endpoint + '/api/v0/cat', params=params, auth=(projectId, projectSecret))
print(response2)
print(response2.text)

### REMOVE OBJECT WITH PIN/RM ###
response3 = requests.post(endpoint + '/api/v0/pin/rm', params=params, auth=(projectId, projectSecret))
print(response3.json())

Run the script with python index.py.

Output something like:

<Response [200]>
QmWtBbpKST49AQFLx8HAdwwjUu7HBP2wrtAH1x8df5qrVm
<Response [200]>
myNFT.png
{'Pins': ['QmWtBbpKST49AQFLx8HAdwwjUu7HBP2wrtAH1x8df5qrVm']}

kubo-rpc-client​

Use the official kubo-rpc-client JavaScript client library.

Install the library with npm install --save kubo-rpc-client.

Save the following script to a file, e.g. index.mjs.

import { create } from 'kubo-rpc-client'

const projectId = "<API_KEY>";
const projectSecret = "<API_KEY_SECRET>";
const auth =
  "Basic " + Buffer.from(projectId + ":" + projectSecret).toString("base64");

const client = create({
  host: "ipfs.infura.io",
  port: 5001,
  protocol: "https",
  headers: {
    authorization: auth,
  },
});

client.pin.add("QmeGAVddnBSnKc1DLE7DLV9uuTqo5F7QbaveTjr45JUdQn").then((res) => {
  console.log(res);
});

Run with node index.mjs.

Output something like:

CID(QmeGAVddnBSnKc1DLE7DLV9uuTqo5F7QbaveTjr45JUdQn)

go-ipfs-api​

  • Use the official IPFS go-ipfs-api GoLang API.
  • Install with go get -u github.com/ipfs/go-ipfs-api.
  • Create a go module with go mod init infura.
  • Save the following script to a file, e.g. index.go, and include the Infura auth header with the http.RoundTripper wrapper.
package main

import (
	"fmt"
	"net/http"
	"os"
	"strings"

	ipfsApi "github.com/ipfs/go-ipfs-api" // v0.2.0
)

func main() {
	projectId := "<API_KEY>"
	projectSecret := "<API_KEY_SECRET>"

	shell := ipfsApi.NewShellWithClient("https://ipfs.infura.io:5001", NewClient(projectId, projectSecret))
	cid, err := shell.Add(strings.NewReader("Infura IPFS - Getting started demo."))
	if err != nil {
		fmt.Println(err)
		os.Exit(1)
	}

	fmt.Printf("Data successfully stored in IPFS: %v\n", cid)
}

// NewClient creates an http.Client that automatically perform basic auth on each request.
func NewClient(projectId, projectSecret string) *http.Client {
	return &http.Client{
		Transport: authTransport{
			RoundTripper:  http.DefaultTransport,
			ProjectId:     projectId,
			ProjectSecret: projectSecret,
		},
	}
}

// authTransport decorates each request with a basic auth header.
type authTransport struct {
	http.RoundTripper
	ProjectId     string
	ProjectSecret string
}

func (t authTransport) RoundTrip(r *http.Request) (*http.Response, error) {
	r.SetBasicAuth(t.ProjectId, t.ProjectSecret)
	return t.RoundTripper.RoundTrip(r)
}

Run with go run index.go.

Output something like:

CID(QmeGAVddnBSnKc1DLE7DLV9uuTqo5F7QbaveTjr45JUdQn)

go-ipfs-http-client​

  • Use the official IPFS go-ipfs-http-client GoLang API.
  • Install with go get github.com/ipfs/go-ipfs-http-client.
  • Create a go module with go mod init infura.
  • Save the following script to a file, e.g. index.go, and include the Infura auth header with the http.RoundTripper wrapper.
package main

import (
	"context"
	"encoding/base64"
	"fmt"
	"net/http"
	"os"
	"strings"

	ipfsFiles "github.com/ipfs/go-ipfs-files" // v0.0.8
	ipfsApi "github.com/ipfs/go-ipfs-http-client" // v0.1.0
)

func main() {
	projectId := "<API_KEY>"
	projectSecret := "<API_KEY_SECRET>"

	httpClient := &http.Client{}
	httpApi, err := ipfsApi.NewURLApiWithClient("https://ipfs.infura.io:5001", httpClient)
	if err != nil {
		fmt.Println(err)
		os.Exit(1)
	}
	httpApi.Headers.Add("Authorization", "Basic " + basicAuth(projectId, projectSecret))

	content := strings.NewReader("Infura IPFS - Getting started demo.")
	p, err := httpApi.Unixfs().Add(context.Background(), ipfsFiles.NewReaderFile(content))
	if err != nil {
		fmt.Println(err)
		os.Exit(1)
	}

	fmt.Printf("Data successfully stored in IPFS: %v\n", p.Cid().String())
}

func basicAuth(projectId, projectSecret string) string {
	auth := projectId + ":" + projectSecret
	return base64.StdEncoding.EncodeToString([]byte(auth))
}

Run with go run index.go.

Example output:

Next Steps​

Now that you have successfully made a call to the IPFS network, you can explore more functionalities and APIs provided by Infura. Here are some suggestions:

  • Explore other IPFS APIs: Infura supports a wide range of APIs. You can find more information in the JSON-RPC API method documentation.

  • Try out different networks: Infura supports multiple networks including Arbitrum, Linea, Polygon, Optimism, and more.

  • Monitor your usage: Keep an eye on your usage on the Infura dashboard to ensure you're not hitting your rate limits.
