173 - OZ ERC-165

OpenZeppelin ERC165: In Solidity, it’s frequently helpful to know whether or not a contract supports an interface you’d like to use.

ERC165 is a standard that helps do runtime interface detection using a lookup table.

You can register interfaces using _registerInterface(bytes4) and supportsInterface(bytes4 interfaceId) returns a bool indicating if that interface is supported or not.
