How to Query NFT Collection Data Using NFT API?
As of today, NFT sales on the Ethereum have reached an all-time high of over $24 billion, up 20% from January, and the number of on-chain transactions has exceeded 9 million.
A large number of highly sought after collectibles have emerged in NFT trading, such as the Meebits series Cryptopunks, which saw a 17.17% increase in sales to more than $2.8 million in 24 hours.Yuga Labs announced that it has acquired the IP collection of CryptoPunks and Meebits NFT from Larva Labs, as well as the recent popularity of Moonbirds in the community. Different kinds of NFT have appeared on the world stage.
ERC721 and ERC20
We see all kinds of news about NFT all the time, going back to the source, what is NFT?
The NFT originated with the Ethereum Implementation Proposal 721 (EIP-721) in late 2017. Non-fungible tokens contain identifying information recorded in their smart contracts. This information makes each token unique and therefore cannot be directly replaced by another token.
The list of ERC721 tokens on Ethereum and the transfer information of each token can be queried using the Tokenview Ethereum explorer.

The following table lists the differences between ERC20 and ERC721:
ERC1155
The ERC-20 and ERC-721 tokens are incompatible with each other. Thus, the ERC-1155 token protocol standard stands out for cross-chain compatibility. The ERC-1155 standard also makes its assets compatible with other ecosystems and able to operate across multiple blockchains.
Similarly, you can use the Tokenview Ethereum explorer to view ERC1155 tokens transaction information .Top of the list is Opensea Shared Storefront, launched by Opensea, which made 3,773 transfers in 24 hours.
