# Solana ATA 检测与构建

> 检测 Solana ATA 并构建创建交易。

检测 Solana ATA 并构建创建交易。

> [!NOTE]
>
> 使用 Broker API Key 调用，并在请求头提供 `X-User-Wallet-Address`。网关会校验钱包与 Broker 的归属关系。 认证规则见[Broker API Key 与签名](https://dexbuilder.mintlify.site/api-reference/common/broker-authentication.md)。

## 使用说明

* 此接口仅使用 Solana 钱包地址，`X-User-Wallet-Address` 不应填写 EVM `0x` 地址。`payer_address` 为用户已绑定的 Solana 钱包，承担链上 rent 和手续费；`target_address` 为 ATA 所属 owner。
* 当 `status=0` 时，用户签名并广播返回的 base64 `tx_data` 后再提现；当 `status=1` 时，ATA 已存在，`tx_data` 为空。失败后可重新查询和构建。
