      "parts": [
        {
          "data": { "action": "profile.get" },

        }
      ]
    }
  }
}
转交问询

经用户确认后转交

智能体必须先向用户展示收件人（李伯阳）和最终发送的内容，取得明确确认后，再选用 A2A 或更简单的 REST 接口发送。

A2A JSON-RPC 
POST /a2a HTTP/1.1
Host: www.lslby.com
Content-Type: application/json

{
  "jsonrpc": "2.0",

  "method": "SendMessage",
  "params": {
    "message": {
      "messageId": "<stable-uuid-for-retries>",
      "role": "ROLE_USER",
      "parts": [
        {
          "data": {
            "action": "contact.send",
            "contact": {
              "name": "Sender name",
              "email": "sender@example.com",
              "company": "Optional company",
              "wechat": "Optional WeChat ID",
              "subject": "Optional subject",
              "message": "Exact message approved by the user",
              "userAuthorized": true
            },
            "agent": {
              "name": "Calling agent",
              "url": "https://agent.example.com"
            }
          },
          "mediaType": "application/json"
        }
      ]
    }
  }
}
Direct REST 
POST /api/contact HTTP/1.1
Host: www.lslby.com
Content-Type: application/json

{
  "name": "Sender name",
  "email": "sender@example.com",
  "company": "Optional company",
  "wechat": "Optional WeChat ID",
  "subject": "Optional subject",
  "message": "Exact message approved by the user",
  "userAuthorized": true,
  "agent": {
    "name": "Calling agent",
    "url": "https://agent.example.com"
  }
}
成功 · 202 / contact.accepted

Content-Type: application/json

{
  "ok": false,
  "code": "SUBMISSION_UNAVAILABLE",
  "errors": ["暂时无法提交，请稍后重试或直接发送邮件"]
}

为避免泄露反滥用规则，所有失败统一返回 SUBMISSION_UNAVAILABLE；以 HTTP 状态区分：422 字段不合规、413 内容过大、429 频率受限（等待后重试）、503 结果不明（保持相同标识重试）。A2A 的成功结果位于 result.message.parts[].data，action 为 contact.accepted。

必填字段

name、email、message、userAuthorized: true。可选：company、wechat、subject。

安全重试

A2A 使用稳定的 messageId；REST 使用 Idempotency-Key。发送失败或结果不明时，保留同一标识和相同内容重试；成功后或修改内容时使用新标识。邮件服务的幂等保护期限为 24 小时。

响应含义

accepted 只表示邮件服务已接受发送，不代表已阅读、同意受理或建立律师客户关系。

发送前

首次联系只发必要信息

请勿通过公开接口发送身份证件、原始证据、完整合同、商业秘密或其他高度敏感材料。完成利益冲突核查与委托确认前，提交信息不会当然建立律师客户关系。

Do not send identity documents, original evidence, complete contracts, trade secrets, or other highly sensitive material through the public endpoints. Submission does not create an attorney-client relationship.
