# 用户标签

## <mark style="color:blue;">GET</mark> /api/v1/tag

* 说明： 通过这个 API，你讲可以查询用户授权的标签数据。不同类型的项目或组织通过 [Relation Protocol](broken://spaces/SjGrUPnpz0dtKyVrOs0l) 发行的 SBTs 被不同的用户持有，同时也证明用户参与了相关的项目或者活动，并与不同类型的项目或组织存在链上关系，我们会根据项目或组织的类型为用户标记对应的标签。比如：Game-Fi、De-Fi 等。该数据需用 [Lit Protocol 解密](/relation-graph/g-zh/guide/use-litprotocol-to-decrypt.md)。
