  title: Ankr NFT Collection Audit
  summary: Pull a collection's holders and then its transfer history.
  description: >-
    Audits an NFT contract by first listing the current holders with
    ankr_getNFTHolders, then pulling the contract's transfer history with
    ankr_getNftTransfers over a block window so a caller can correlate who holds
    the collection now with how it changed hands. Each step is written out inline
    as a JSON-RPC call so the flow can be read and executed without opening the
    underlying OpenAPI description.
