const response = await Moralis.EvmApi.nft.getContractNFTs({handle,});
The “getNFTContractMetadata” and “getContractNFTs” endpoints are part of Moralis’ final NFT API. In the event you’ve used Moralis earlier than and are proficient in JavaScript, you probably know make the most of the above strains of code to get NFT assortment information. Then again, this can be your first rodeo with Moralis. In that case, it is best to full this step-by-step tutorial. You simply must create your free Moralis account and observe our lead!
Overview
NFTs proceed to be one of the widespread blockchain use circumstances. They provide numerous alternatives to create decentralized functions (dapps) that not directly incorporate NFTs. This may be NFT explorers, NFT trackers, NFT-gated web sites, Web3 video games, and many others. Furthermore, everytime you wish to construct NFT-related dapps, the power to get NFT assortment information makes issues rather a lot less complicated, and utilizing the above two snippets of code is one of the simplest ways to go.
Shifting ahead, we’ll first clarify what NFT assortment information is and what sort of information an NFT assortment retailer. Then, we’ll look carefully on the final information software for NFT collections – the Moralis Web3 API. That is the place you’ll get higher acquainted with the Moralis NFT API and the “getNFTContractMetadata” and “getContractNFTs” endpoints. Whereas these are the 2 core instruments to get NFT assortment information, you may take issues additional with Moralis’ Web3 infrastructure answer. As an example, you need to use Web3 streams, which allow you to create Ethereum webhooks to effortlessly stream on-chain occasions on to your backend.

As soon as you understand what parameters the above two endpoints absorb and check them, you’ll be able to tackle at present’s tutorial. After all, you may mix the 2 endpoints in the identical script. Nonetheless, for the sake of readability, we’ll present you work with the “getContractNFTs” endpoint. In any case, the latter gives you with extra particulars.
What’s NFT Assortment Knowledge?
NFT assortment information check with totally different items of details about a group. Nonetheless, we regularly check with particulars relating to NFTs in a selected assortment as NFT assortment information. As such, NFT assortment information sometimes additionally refers to NFT metadata. Furthermore, it’s value declaring that NFTs might be assigned to collections (and sometimes are), however this isn’t important. In any case, an NFT might be fully impartial. Nonetheless, NFT creators very often assign a bigger quantity of tokens to a single assortment. A terrific instance is the CryptoPunks assortment, which incorporates near 10,000 NFTs. Finally, with a purpose to know what NFT assortment information is, it’s good to correctly perceive what NFTs and NFT metadata are.
What are Non-Fungible Tokens?
Non-fungible tokens, or NFTs, are distinctive non-interchangeable crypto property. Every NFT has its distinctive token ID (an on-chain signature), which makes these tokens ultimate for representing distinctive digital or bodily objects. For this reason digital artwork and digital collectibles are typically the most typical examples of NFT utility. That stated, it is best to remember the fact that NFTs are already revolutionizing many industries (certification, possession proofs, ticketing, gaming, and many others.).
Moreover, you could know that devs create (mint) NFTs utilizing NFT sensible contracts. The latter are on-chain items of software program that incorporate all of the required and non-compulsory particulars in regards to the NFT they give attention to. Furthermore, the identical sensible contract is behind all NFTs in a single assortment. Therefore, to get NFTs from a group, it’s good to give attention to the acceptable sensible contract for that assortment.
What’s NFT Metadata?
NFT metadata gives details about the info associated to an NFT. Furthermore, trying on the above picture ought to provide you with a strong concept of what sort of particulars NFT metadata contains. It’s additionally necessary to notice that the NFT metadata itself will not be saved on the blockchain, nor are the NFT-representing recordsdata (typically JPEGs however might be some other file codecs). As a substitute, devs use cloud storage options (ideally decentralized ones) to retailer these recordsdata and the metadata recordsdata. The latter contains the NFT-representing recordsdata’ location hyperlinks (URLs). That’s the reason the ability of getting NFT metadata additionally lets you get the NFT-representing recordsdata.
Moreover, metadata recordsdata normally are available JSON format. The hyperlinks pointing to those recordsdata (as soon as saved on-line) are known as URIs. Word that the precise particulars included in NFT metadata fluctuate. Nonetheless, you typically know what you’re coping with since NFT requirements are set in place (ERC-721, ERC-1155, SPL, and many others.). For instance, within the case of ERC-721 or ERC-1155 requirements, metadata normally features a description, a reputation, an NFT-representing file vacation spot, and non-compulsory attributes or traits. To be taught extra about attributes, try our “How you can Add Attributes to NFT Metadata” article!
What Knowledge is Saved in an NFT Assortment?
NFT collections are minted and ruled by sensible contracts. As such, the small print in an NFT assortment are the small print that the gathering’s sensible contract holds. These mostly embody the full variety of NFTs in a group, the gathering identify, the gathering image, the bottom token URI, and all the small print of particular person NFTs in that assortment. Additionally, a few of the most necessary NFT particulars come within the type of NFT metadata (URIs). Furthermore, the latter contains NFT-representing recordsdata and different required and non-compulsory particulars, as defined above. Nonetheless, one of the simplest ways to see what sort of information is saved in an NFT assortment is to make use of the “getNFTContractMetadata” and “getContractNFTs” endpoints.
Final Knowledge Device for NFT Collections
Moralis is the final word information software for NFT collections, particularly because of the “getNFTContractMetadata” and “getContractNFTs” NFT API endpoints. As such, we encourage you to take a better take a look at every of the 2 endpoints by utilizing the Moralis documentation. So, let’s begin by trying on the “getNFTContractMetadata” endpoint and its documentation web page within the subsequent part!
Exploring the “getNFTContractMetadata” NFT API Endpoint
Right here’s the screenshot of the get assortment metadata endpoint‘s documentation web page:
As you may see within the picture above, this endpoint fetches the gathering (contract) stage metadata for a given sensible contract. To do that, it requires an handle of the NFT contract of curiosity. Furthermore, this makes the “handle” parameter important. As well as, the “getNFTContractMetadata” endpoint additionally lets you choose which chain to question utilizing the “chain” parameter.
You should utilize the top-right portion of the above web page to pick out the programming language you wish to use and check out the code as illustrated within the above picture.
Exploring the “getContractNFTs” NFT API Endpoint
Not like the “getNFTContractMetadata” endpoint that fetches the collection-level metadata, “getContractNFTs” will get considerably extra particulars. It additionally fetches the metadata for all NFTs within the focused assortment and gives further non-compulsory parameters. After ending this text, be sure to take a look at one in every of our different articles explaining get all NFTs from contract. That stated, let’s now be sure to discover the get NFTs by contract documentation web page as properly:
As defined within the earlier part, you need to use the documentation web page for getting NFTs by contract to take the “getContractNFTs” for a check spin and replica the required strains of code for varied programming languages.
Nonetheless, listed below are all of the parameters that this endpoint takes in:
- “handle“ – This parameter serves to offer an NFT sensible contract handle and is the one required parameter.
- “chain“ – You should utilize this parameter to find out which programmable chain to focus on (Moralis helps all main Web3 networks).
- “format“ – This parameter enables you to decide what sort of token ID format you wish to work with (decimal or HEX).
- “restrict“ – You should utilize this parameter to set the specified web page dimension of the consequence.
- “totalRange“ – This parameter enables you to decide the variety of subranges to separate the outcomes into.
- “vary“ – You should utilize this parameter to set the specified subrange to question.
- “cursor“ – This parameter lets you get to the subsequent web page when you may have greater than 100 NFTs or wish to show even fewer NFTs per web page.
- “normalizeMetadata” – You should utilize this parameter if you wish to get normalized metadata. In case you choose “true”, the endpoint returns metadata in a standardized construction in a brand new object known as “normalized_metadata“.
How you can Get NFT Assortment Knowledge with Moralis
Now that you understand the gist of each endpoints that allow you to fetch NFT assortment information, it’s time for at present’s tutorial. Since “getContractNFTs” gives you with extra particulars, we’ll focus our tutorial on this endpoint. Nonetheless, the steps to make use of “getNFTContractMetadata” are mainly the identical. As such, you’ll know precisely put it to use after following our lead beneath.
First issues first, be sure to finish three stipulations:
- Put together your favourite code editor or IDE. We have a tendency to make use of Visible Studio Code (VSC).
