Look up a BSN account
Use for a general account lookup. Return the public BSN Expert account card: profile, membership type, balances, ownership, signatures, multisig data, and a compact summary of known incoming and outgoing tags. The summary names bsn.account.tags as the tool for linked accounts, unknown tags, and reciprocal-pair details.
Get an account's BSN tags
Use when the question is specifically about an account's tags or relationships. Return all incoming and outgoing BSN tag links with linked accounts, including unknown tags and whether the matching reciprocal pair exists. Do not call after bsn.account.get when its compact tag summary already answers the question.
List BSN relationship tags
Return the BSN relationship-tag catalog with localized descriptions, categories, single-value rules, pair type, reciprocal tag, and strong-pair requirement.
