ERC-721
ERC-721 is the Ethereum standard for non-fungible tokens — assets that are individually distinguishable rather than interchangeable. It defines ownership, transfer and approval for unique token IDs, and a metadata extension pointing at the content a token represents.
Also known as EIP-721, ERC721, Non-Fungible Token Standard.
Providers that carry ERC-721 3
These providers' own APIs.json profiles carry ERC-721 as a tag — the provider's statement that the standard is part of what it does. APIs.io has not verified the implementation on this page; the de facto profiles on this site are where that measurement exists. Ordered by Kin Score.
Read from the API Evangelist standards directory. Provider links come from the catalog's own identity tags and are rebuilt nightly. If this page is wrong about a standard or a provider, say so.
