Resolve a handle or a TCB IBAN to a member

Supply exactly one of handle or iban, and optionally the name you believe you are paying. The answer carries the verified legal name, the currencies that member can receive, and a verdict on your name: MATCH is the legal name exactly, CLOSE_MATCH is a trading name or a near miss, NO_MATCH is neither, and null means you supplied no name to check. Cite resolveToken on POST /settlements so what you were shown is what you pay; it lasts ten minutes.

Query Parameters

handle?string
iban?string
name?string

The name you believe you are paying.

Header Parameters

x-on-behalf-of?string

Act on behalf of one of your sub-clients. The value is that sub-client id, and the request then reads and writes that sub-client's own accounts and registry rows rather than yours. Omit it to act as yourself. A route that does not accept the header refuses it with 400 ON_BEHALF_OF_NOT_ALLOWED_HERE rather than ignoring it — that includes every vault route (deposits, withdrawals, conversions, sub-accounts, positions), the webhook registry, and POST /sub-clients, since a sub-client never has sub-clients of its own. An id that is not one of your sub-clients answers 404 ON_BEHALF_OF_NOT_FOUND; a closed one answers 409 ON_BEHALF_OF_SUB_CLIENT_CLOSED; and a key restricted to a subset of your sub-clients answers 403 ON_BEHALF_OF_NOT_ALLOWED_FOR_KEY for any node outside it.

Create or amend the network profile PUT

The handle is set once. Sending a different handle later is refused with 409 HANDLE_IMMUTABLE — changing one is a support action, because a handle that could be re-issued is one a payer's saved payee could silently start pointing at somebody else. With x-on-behalf-of the profile is that sub-client's, and its handle is namespaced under yours: acme/zayn-retail.

Search the member directory GET

Prefix match on handle, legal name and trading names, over members who turned discoverability on. At least two characters, at most 20 rows, cursor-paginated. It never returns IBANs, never a member who is not discoverable, and never your own tree. An exact handle or IBAN resolves anyone regardless of discoverability — use GET /network/resolve.
