# Check owner of token

`GET /v4/data/owners/address`

/v4/data/owners/address

**50 credit per API call**

\> 📘 \*\*Note for v3 API users:\*\* > > As part of our documentation consolidation, we removed the dedicated page for GET /v3/data/owners/address. Users can refer to GET /v4/data/owners/address for the latest documentation, as both endpoints function the same—simply replace v4 with v3 in the API URL if using the v3 version.
