title_body: How to query a Cardano node for an NFT's owner?
upvoted_answer: There is no way to find that information without syncing the whole blockchain into a database with a tool such as cardano-db-sync.
  This takes a lot of time and resources, so you might want to use an API like blockfrost.io to query the addresses owning a specific token.
  $ curl  -s -H &quot;Project_id: $BLOCKFROST_PROJECT_ID&quot; https://cardano-mainnet.blockfrost.io/api/v0/assets/00000002df633853f6a47465c9496721d2d5b1291b8398016c0e87ae6e7574636f696e/addresses | jq
    [
     {
      &quot;address&quot;: &quot;addr1qxlmfhfcjck5pctuvlpww3kuxvqjucz40qusgeqgmyqq4utntgjccmteyrsldd67rxv2yq6ew2a7t48q34p9j7nf0kjqskku78&quot;,
      &quot;quantity&quot;: &quot;1&quot;
     }
    ]
