NFT data at your fingertips

Quickstart covers:

  1. How to retrieve NFTs owned by an account/wallet

  2. How to retrieve NFTs from a contract

  3. How to retrieve details of an NFT

  4. How to retrieve all NFTs

Prerequisites

1. How to retrieve NFTs owned by an account/wallet

NFTs owned by an account

Using our Retrieve NFTs owned by an account API you can retrieve NFTs owned by an account/wallet. It currently supports Ethereum and Polygon. It can be useful for building a gallery, creating a user NFT profile page, adding an NFT portfolio section to your app, checking if a user owns a specific NFT and then unlocking specific activity, etc.

  • Set account_address to the account/wallet address which NFTs you want to see. We'll use 0x51688cd36c18891167e8036bde2a8fb10ec80c43
  • Pick the chain you want to query, e.g. ethereum or polygon. We'll use ethereum.
  • Add your API key to Authorization. This will be automatically prefilled if you are signed in (top right of this page). Sign up if you don't have an API key yet - it's free.
curl --request GET \
  --url 'https://api.nftport.xyz/v0/accounts/0x51688cd36c18891167e8036bde2a8fb10ec80c43?chain=ethereum&include=metadata' \
  --header 'Authorization: <<apiKey>>'

import requests

url = "https://api.nftport.xyz/v0/accounts/0x51688cd36c18891167e8036bde2a8fb10ec80c43?chain=ethereum&include=metadata"

headers = {
  "Authorization": "<<apiKey>>"
}

response = requests.get(url, headers=headers)

print(response.json())

const options = {
  method: 'GET',
  headers: {'Content-Type': 'application/json', Authorization: "<<apiKey>>}
};

fetch('https://api.nftport.xyz/v0/accounts/account_address?chain=ethereum', options)
  .then(response => response.json())
  .then(response => console.log(response))
  .catch(err => console.error(err));

It's also possible to have more granular control over the response and set filters. For this, see the API reference and more code samples: Retrieve NFTs owned by an account API.

2. How to retrieve NFTs from a contract

NFTs in a contract address

Using our Retrieve contract NFTs API you can get all NFTs for a given contract address. Currently, Ethereum (Mainnet and Goerli) and Polygon are supported. Using this API you can import all NFTs from a given contract to your application or showcase NFTs in a particular collection.

  • Set contract_address to the contract address which NFTs you want to see. We'll use0xBC4CA0EdA7647A8aB7C2061c2E118A18a936f13D - the Bored Ape Yacht Club contract.
  • Pick the chain you want to query, e.g. ethereum or polygon. We'll use ethereum.
  • Add your API key to Authorization. This will be automatically prefilled if you are signed in (top right of this page). Sign up if you don't have an API key yet - it's free.
curl --request GET \
  --url 'https://api.nftport.xyz/v0/nfts/0xBC4CA0EdA7647A8aB7C2061c2E118A18a936f13D?chain=ethereum&include=metadata' \
  --header 'Authorization: <<apiKey>>'

import requests

url = "https://api.nftport.xyz/v0/nfts/0xBC4CA0EdA7647A8aB7C2061c2E118A18a936f13D?chain=ethereum&include=metadata"

headers = {
  "Authorization": "<<apiKey>>"
}

response = requests.get(url, headers=headers)

print(response.json())

const options = {
  method: 'GET',
  headers: {'Content-Type': 'application/json', Authorization: <<apiKey>>}
};

fetch('https://api.nftport.xyz/v0/nfts/contract_address?chain=ethereum', options)
  .then(response => response.json())
  .then(response => console.log(response))
  .catch(err => console.error(err));

It's also possible to have more granular control over the response and set filters. For this, see the API reference and more code samples: Retrieve contract NFTs API.

3. How to retrieve details of an NFT

NFT Details

Using our Retrieve NFT details API you can get all details for a given NFT. Currently Ethereum (Mainnet and Goerli) and Polygon are supported.

  • Set contract_address from which you want to retreive details of an NFT. We'll use 0x23581767a106ae21c074b2276d25e5c3e136a68b- the Moonbirds contract, on the ethereum chain.
  • Set token_id of the NFT from the above contract. We'll use 1446.
  • Add your API key to Authorization. This will be automatically prefilled if you are signed in (top right of this page). Sign up if you don't have an API key yet - it's free.
curl --request GET \
  --url 'https://api.nftport.xyz/v0/nfts/0x23581767a106ae21c074b2276d25e5c3e136a68b/1446?chain=ethereum' \
  --header 'Authorization: <<apiKey>>'

import requests

url = "https://api.nftport.xyz/v0/nfts/0x23581767a106ae21c074b2276d25e5c3e136a68b/1446?chain=ethereum"

headers = {
  "Authorization": "<<apiKey>>"
}

response = requests.get(url, headers=headers)

print(response.json())

const options = {
  method: 'GET',
  headers: {'Content-Type': 'application/json', Authorization: '<<apiKey>>'}
};

fetch('https://api.nftport.xyz/v0/nfts/contract_address/token_id?chain=ethereum', options)
  .then(response => response.json())
  .then(response => console.log(response))
  .catch(err => console.error(err));

It's also possible to have more granular control over the response and set filters. For this, see the API reference and more code samples: Retrieve NFT details API.

4. How to retrieve all NFTs (optional)

Using our Retrieve all NFTs API you can query all ERC721 and ERC1155 NFTs that have been minted on a given chain. Currently, Ethereum (Mainnet and Goerli) and Polygon are supported.

You can run various analytics with the data, import all NFTs to your application/marketplace, keep track of all the created NFTs, etc.

Non-enterprise users can fetch only the last 3 months of data using this endpoint. If you want to get all NFT data, contact us.

  • Pick the chain you want to query, e.g. ethereum or polygon.
  • Choose the level of detail with include, e.g. file_information or contract_information. See other options in the Retrieve All NFTs API reference.
  • Add your API key to Authorization. This will be automatically prefilled if you are signed in (top right of this page). Sign up if you don't have an API key yet - it's free.
curl --request GET \
  --url 'https://api.nftport.xyz/v0/nfts?chain=ethereum&include=metadata' \
  --header 'Authorization: <<apiKey>>'

import requests

url = "https://api.nftport.xyz/v0/nfts?chain=ethereum&include=metadata"

headers = {
  "Authorization": "<<apiKey>>"
}

response = requests.get(url, headers=headers)

print(response.json())

const options = {
  method: 'GET',
  headers: {'Content-Type': 'application/json', Authorization: '<<apiKey>>'}
};

fetch('https://api.nftport.xyz/v0/nfts?chain=polygon&include=default', options)
  .then(response => response.json())
  .then(response => console.log(response))
  .catch(err => console.error(err));

It's also possible to have more granular control over the response and set filters. For this, see the API reference and more code samples: Retrieve all NFTs API.
