i've minted some NFTs with 721 metadata in the transaction and am now looking to retrieve the metadata information for further processing. I've send these NFTs around a bit so the utxo is not the minting transaction. Is there a way to retrieve this information using the cardano-cli or cardano-wallet commandline? Or are there other suggestions for doing this. I'm working on the testnet currently. Thanks a lot in advance!

I found that it is possible in the following way:

Alternatively, you can use https://github.com/input-output-hk/cardano-db-sync to sync the whole node to Postgres DB from where you can query metadata https://forum.cardano.org/t/cardano-db-sync-query-metadata/74386

The third way is to use https://input-output-hk.github.io/offchain-metadata-tools/. By my understanding, the main purpose of this tool is to verify native tokens. It requires to be done pull request to git and after approval, you can do a query with this https://input-output-hk.github.io/offchain-metadata-tools/api/latest/

Cardanoscan can be used to browse the metadata. Similar services is also available in test net. Sample output is like this

  • I guess the problem is to find a specific transaction, among all millions or billions of transactions that may exist on the block-chain. There are efforts like covalent ( covalenthq.com) that provide search services but I don't know if that is available for cardano.
