Send Your First API Request

This tutorial will help you send your first API request using Blockdaemon. We’ll walk you through how to:

Get your API credentials
Use the access token to make your first request

Step 1: Get Your API Credentials

Log in to the Blockdaemon Dashboard, or sign up if you don’t have an account.
In the left sidebar, select the APIs you want to use:

Product	API Key
RPC, API Suite, and DeFi	You can get a free test key. To create live keys, upgrade your plan — learn more here .
Dedicated Nodes	You’ll need to deploy a node first. Then, you'll get the Auth String & Auth Token to authenticate the request.
Staking API	API keys are not created automatically when a staking configuration is set up. To create a key: Go to the Staking API Overview page. If your workspace has an active staking configuration, you’ll be able to generate a key there. If not, you can access the page, but key creation is disabled until a configuration is enabled for your workspace.

Staking API

API keys are not created automatically when a staking configuration is set up.

To create a key:

Go to the Staking API Overview page.
If your workspace has an active staking configuration, you’ll be able to generate a key there.
If not, you can access the page, but key creation is disabled until a configuration is enabled for your workspace.

Step 2: Make Your First API Call

In this example, we'll call the Get Protocols Overview endpoint from Blockdaemon’s REST API:

curl --request GET \
     --url https://svc.blockdaemon.com/universal/v1/ \
     --header 'X-API-Key: YOUR_API_KEY' \
     --header 'accept: application/json'

If successful, you’ll see a response like this:
