This is an output item of JSON result obtained by the API of blockchain.info:


Is it possible to obtain the content of the field "addr_tag_link" and "addr_tag" in java without using the API of blockchain.info (such as with bitcoinj)?


No, the addr_tags are specific to blockchain.info - they are not kept on the Bitcoin blockchain, but rather on blockchain.info's servers.
