Overview

Our NFT endpoints support advanced querying options, allowing you to retrieve the exact data you need with a single request.

This page includes short, step-by-step tutorials explaining how to get information on NFT assets in the Ethereum Mainnet network.

All example queries are based on the following endpoints:.


How to Get NFTs Owned by a Wallet

This tutorial explains the steps involved in getting a list of Ethereum Mainnet NFTs owned by any given wallet.

Step 1. Use the assets endpoint with the following details:

  • protocol: ethereum
  • network: mainnet
https://svc.blockdaemon.com/nft/v1/ethereum/mainnet/assets

Step 2. Add the following parameter:

  • wallet address
    • parameter: wallet_address
    • value: e.g. 0x5682035b6b1D04924C7661b09A974fF0695De6bE
  • wallet filter
    • parameter: show_wallets
    • value: e.g. true
https://svc.blockdaemon.com/nft/v1/ethereum/mainnet/assets?wallet_address=0x5682035b6b1D04924C7661b09A974fF0695De6bE&show_wallets=true

Step 3. Execute the query.

For example, in cURL you should run the following code:

curl -X GET 'https://svc.blockdaemon.com/nft/v1/ethereum/mainnet/assets?wallet_address=0x5682035b6b1D04924C7661b09A974fF0695De6bE&show_wallets=true' -H 'Authorization: Bearer YOUR_API_KEY'

Note: To authorize your request, you need to get a Ubiquity API key and use it as a bearer token or a query parameter. Learn more: Authentication Guide

Step 4. Your results will look something like this example response.


How to Get All ERC-1155 NFTs Owned by a Wallet

This tutorial explains the steps involved in getting a list of Ethereum Mainnet ERC-1155 NFTs owned by any given wallet.
Step 1. Use the assets endpoint with the following details:

Note: The following token types are also available: ERC20, CRYPTOPUNKS

Step 3. Execute the query.

For example, in cURL you should run the following code:

curl -X GET 'https://svc.blockdaemon.com/nft/v1/ethereum/mainnet/assets?wallet_address=0x5682035b6b1D04924C7661b09A974fF0695De6bE&token_type=ERC1155&show_wallets=true' -H 'Authorization: Bearer YOUR_API_KEY'

Note: To authorize your request, you need to get a Ubiquity API key and use it as a bearer token or a query parameter. Learn more: Authentication Guide

Step 4. Your results will look something like this example response.

The response does not contain token types, but you can get them with another endpoint:


How to Verify That a Wallet Owns an NFT

This tutorial explains the steps involved in verifying that a given wallet in the Ethereum Mainnet network owns a given NFT.

Step 1. Use the assets endpoint with the following details:

Step 3. Execute the query.

For example, in cURL you should run the following code:

curl -X GET 'https://svc.blockdaemon.com/nft/v1/ethereum/mainnet/assets?contract_address=0xBC4CA0EdA7647A8aB7C2061c2E118A18a936f13D&token_id=9999&wallet_address=0x46Fd6B647Dc8C82aD8f6cf0CC6b22ACad3f6e39d&show_wallets=true' -H 'Authorization: Bearer YOUR_API_KEY'

Note: To authorize your request, you need to get a Ubiquity API key and use it as a bearer token or a query parameter. Learn more: Authentication Guide

Step 4. If the specified NFT is owned by the wallet, the query will return the NFT. Your results will look something like this example response.

If the ownership is not verified, the query will return an empty array:


{
    "data": [],
    "meta": null
}

How to Get All NFTs for a Smart Contract

The response does not contain mint dates, but you can get them with another endpoint:


How to Render the Image Associated with an NFT

This tutorial explains the steps involved in rendering the image associated with a given NFT in the Ethereum Mainnet network.

Notes:

  • Image URLs are returned for assets from the top popular collections. All images are cached by Blockdaemon for quick access.
  • Blockdaemon collects NFT information and data from various third-party sources (“NFT Content”). We do not create, own or control NFT Content and we do not routinely monitor NFT Content for violations of these Terms. You acknowledge that Blockdaemon has no responsibility or liability related to NFT Content and agree that you must evaluate, and decide for yourself if you wish to use any NFT Content.

Step 1. Use the assets endpoint with the following details:

  • protocol: ethereum
  • network: mainnet
https://svc.blockdaemon.com/nft/v1/ethereum/mainnet/assets

Step 2. Add the following parameters:

  • contract address
    • parameter: contract_address
    • value: e.g. 0xBC4CA0EdA7647A8aB7C2061c2E118A18a936f13D

    • parameter: token_id
    • value: e.g. 9999
https://svc.blockdaemon.com/nft/v1/ethereum/mainnet/assets?contract_address=0xBC4CA0EdA7647A8aB7C2061c2E118A18a936f13D&token_id=9999

Step 3. Execute the query.

For example, in cURL you should run the following code:

curl -X GET 'https://svc.blockdaemon.com/nft/v1/ethereum/mainnet/assets?contract_address=0xBC4CA0EdA7647A8aB7C2061c2E118A18a936f13D&token_id=9999' -H 'Authorization: Bearer YOUR_API_KEY'

Note: To authorize your request, you need to get a Ubiquity API key and use it as a bearer token or a query parameter. Learn more: Authentication Guide

Step 4. Your results will look something like this example response.

Copy the media path from the image_url field:

{
    "id": "5e1f4454-34ff-5118-9987-96b481625128",
    "token_id": "9999",
    "image_url": "token/0xBC4CA0EdA7647A8aB7C2061c2E118A18a936f13D/5e1f4454-34ff-5118-9987-96b481625128.png",
    ...more properties...
}

Step 5. Finally, you can render the image.

Use the media endpoint with the media path (copied in the previous step):
token/0xBC4CA0EdA7647A8aB7C2061c2E118A18a936f13D/5e1f4454-34ff-5118-9987-96b481625128.png

https://svc.blockdaemon.com/nft/v1/ethereum/mainnet/media/token/0xBC4CA0EdA7647A8aB7C2061c2E118A18a936f13D/5e1f4454-34ff-5118-9987-96b481625128.png
  • In your browser, just use the address bar.
  • In Postman, click on the URL in the response. A tab with a new query will open. Run it, and Postman will render the image.
  • In cURL, run the following code to download the image to your working directory:
curl -X GET 'https://svc.blockdaemon.com/nft/v1/ethereum/mainnet/media/token/0xBC4CA0EdA7647A8aB7C2061c2E118A18a936f13D/5e1f4454-34ff-5118-9987-96b481625128.png' --output YOUR_FILENAME.png -H 'Authorization: Bearer YOUR_API_KEY'

Note: In all cases authentication is required. You need to get a Ubiquity API key and use it as a bearer token or a query parameter when accessing the image. Learn more: Authentication Guide
