https://svc.blockdaemon.com/defi/v1/nft/historicallogs

Extracts detailed historical event logs for NFT collections within a specified block range on Ethereum. Designed to support different NFT standards (such as ERC721 and ERC1155), the endpoint returns granular log data—including event topics, parameters (like from, to, and tokenId), block details, and transaction identifiers—allowing developers and auditors to analyze the full history of NFT-related events, track transfers, and perform forensic or compliance analyses.
