Get Started

We provide rapid and robust access to unified Ethereum on-chain and off-chain NFT data. Follow these steps to get started:

Step 1. Sign Up For an API Key

To use the Blockdaemon NFT API, you need an API key. If you don’t have one, sign up for a free API key by creating an account on the Blockdaemon website. Once signed up, you can access your API key from your Blockdaemon dashboard.

Step 2. Using Your API Key

Once you have your API key, you need to authenticate your API requests. There are several methods to do this:

2.1. Using Your API Key as a Query Parameter,

add the apiKey query parameter to the endpoint URL:

https://svc.blockdaemon.com/nft/v1/{protocol}/{network}/collections/search?apiKey=YOUR_API_KEY

Authentication with a query parameter can be used with any tool - no additional actions are needed.

📘

Info:

Note that if the query has additional parameters, replace ? with &.

2.2. Using Your API Key as a Bearer Token

Add the Authorization header with Bearer YOUR_API_KEY:

- Bearer Token in cURL

For example, to get NFT collections with names matching a given search string using our NFT REST API, use the following code:

curl --request GET 'https://svc.blockdaemon.com/nft/v1/{protocol}/{network}/collections/search' \
--header 'Authorization: Bearer YOUR_API_KEY'

Or, if you prefer to use short options, run the following:

curl -X GET 'https://svc.blockdaemon.com/nft/v1/{protocol}/{network}/collections/search' \
-H 'Authorization: Bearer YOUR_API_KEY'

- Bearer Token in Postman

1. Navigate to the Authorization or Auth tab.
2. Select Bearer Token from the Type drop-down menu.
3. Paste YOUR_API_KEY into the Token input box.

2.3. Using Your API Key as an X-API-Key

You can authenticate Blockdeamon API Suite API requests by passing your YOUR_API_KEY in the X-API-Key header. Here are the instructions for doing this in cURL and Postman.

- X-API-Key in cURL

For example, to get NFT collections with names matching a given search string using our NFT REST API, use the following code:

curl --request GET 'https://svc.blockdaemon.com/nft/v1/{protocol}/{network}/collections/search' 
--header 'X-API-Key: YOUR_API_KEY'

Or, if you prefer to use short options, run the following:

curl -X GET 'https://svc.blockdaemon.com/nft/v1/{protocol}/{network}/collections/search' \
-H 'X-API-Key: YOUR_API_KEY'

- X-API-Key in Postman

1. Go to the Authorization or Auth tab.
2. Select API Key from the Type drop-down menu.
3. Paste your YOUR_API_KEY into the Value input box.
4. Ensure the Add to option is set to Header.

Step 3. Get Familiar with API Endpoints

Learn about the API endpoints and their usage in the NFT REST API Documentation. This will help you understand how to interact with Ethereum on-chain and off-chain NFT data.

Step 4. Test the API

Try sending a request to test the API. For example, use the GET request to retrieve information about an NFT collection:

Option 1: Using API Reference Docs

Try the Get NFT Collection endpoint to get details about an NFT collection. Remember to generate a Blockdaemon API Suite Key for interactive features.

Option 2: Using Your Preferred API Platform

You can also use tools like Postman. Example endpoint:

https://svc.blockdaemon.com/nft/v1/{protocol}/{network}/collection/{id}

Step 5. Integrate the API Into Your Application

After familiarizing yourself with the API and testing it, integrate it into your application to access NFT data.
