NFT API

🖖

NFT API is an Advanced APIs' collection of methods that comes as a unique feature along with other extensive capabilities provided to our Premium Plan users.

NFT API serves to request NFT-related data (owners, listings for particular wallet addresses, collections, time it's been minted, transaction history, and other metadata) across multiple EVM-compatible chains.

NFT API empowers the Web3 projects integrating NFTs (virtual worlds, decentralized games, galleries, marketplaces) to instantly fetch all the necessary information across multiple blockchains in a single request.

NFT API Methods

NFT API consists of the following methods to request NFT-related data across multiple chains:

ankr_getNFTsByOwner

Retrieves the account's NFT data.

Retrieves a list of NFTs (ERC721/ERC1155/ENS/POAP) that belong to the particular account specified.

Request

Build your request using the parameters below.

Parameters

  • id (int64; required): a request ID (example: 1).

  • jsonrpc (string; required): a JSON RPC spec used (example: 2.0).

  • method (string; required): a method used for the request.

  • params (object): the data object containing request body parameters:

    • walletAddress (string; required): an account address to query for NFTs; supports the Ethereum Name Service (ENS).
    • blockchain (string): a chain or a combination of chains to query:
      • Single chain: eth, bsc, fantom, avalanche, polygon, arbitrum, syscoin, optimism.
      • Chains combination: [eth, polygon, bsc].
      • All chains: leave the value empty to query all the chains available.
    • pageSize (int32): a number of page results you'd like to get (default=10, max=50).
    • pageToken (string): a token is provided at the end of the response body and can be referenced in the request to fetch the next page.
    • filter (key-value): Filters your request by either of the following:
      • Smart contract address ("0xd8682bfa6918b0174f287b888e765b9a1b4dc9c3": [] ) — retrieves all NFTs from the address.
      • Smart contract address and NFT ID ("0xd8682bfa6918b0174f287b888e765b9a1b4dc9c3": ["8937"]) — retrieves a particular NFT specified.
