发送前清洗邮件列表，避免退信

Q: 检查涵盖哪些内容？

语法、域名、MX 记录和邮箱状态。

以 JSON 检查邮箱地址的语法、域名、MX 记录和邮箱状态，只向可送达的地址发送，保护你的发件人信誉。

预付费，无订阅REST 或 MCP一个密钥搞定模型、数据和智能体

来自注册表单、展会或抓取线索文件的邮箱列表里总会混有无效地址，向它们发信会推高退信率，损害你的发件人信誉。你想在发出第一封邮件之前，就知道该剔除哪些地址。Lovely Router 替你检查：发送一份地址列表，每个邮箱返回一个 JSON 对象，按邮箱数量从预付费余额中计费。用一个 API 密钥，就能从 CRM 导出脚本、注册流程或 AI 智能体中调用。

交给你的 AI 智能体

把这段提示词复制到 Claude Code、Cursor、Codex 或任何编程智能体中。它会告诉智能体文档在哪里，以及如何使用你的 API 密钥。

发送前清洗邮件列表，避免退信. Use the Lovely Router data tools: each returns JSON and is billed per result.

- Docs (read first): https://lovelyrouter.com/docs/tools/find.md and https://lovelyrouter.com/docs/tools/run.md
- Plan first: POST https://lovelyrouter.com/v1/tools/suggest with `{"task": "<my task in plain words>"}` (free). It returns the tools to run in order, each with an example `input`, the `input_required` fields, an estimated cost and a ready-made `run` request. Replace the example values with my task's; if a field is unclear, read the tool with GET https://lovelyrouter.com/v1/tools/<id>. To browse instead, POST https://lovelyrouter.com/v1/tools/discover searches the catalog.
- Show me the plan and its estimated cost (`total_est_cost_usd`) before running anything large.
- Run: POST https://lovelyrouter.com/v1/tools/<id>/run with `{"input": {...}, "max_results": N}`. A 200 has the finished run with `items`; a 202 means it is still running, so poll the `poll` path until `status` is `succeeded`, `failed`, `timed_out` or `stopped`.
- Only delivered results are billed. Keep max_results small on the first run, check the output, then scale up.
- If you support MCP, connect https://lovelyrouter.com/mcp instead (Streamable HTTP, same key; https://lovelyrouter.com/docs/tools/mcp.md) and use suggest_tools, get_tool and run_tool.
- Auth: read my API key from the LOVELY_API_KEY environment variable and send it as `Authorization: Bearer $LOVELY_API_KEY`. Never print or commit the key. If it is not set, ask me to create one at https://lovelyrouter.com/app/keys.
- Billing is prepaid: every call is charged to my balance, so test with a small request before running anything large.
- Every docs page is plain Markdown; the full index is https://lovelyrouter.com/llms.txt.

My task: <the inputs (links, keywords or accounts) and how many results you need>

工作原理

导出列表
从 CRM、注册数据表或线索表格中取出地址。一个地址算一个邮箱。
运行工具
把它们发送到 POST /v1/tools/email-verify/run，并将 max_results 设为地址的数量。运行会从你的余额中预留它的最高费用，并为每个邮箱返回一条结果。
保留有效地址
把结果写回你的列表。向可送达的地址发送邮件，其余的则屏蔽或人工复核。

一次请求验证一份列表

验证邮箱地址在 emails 中接受地址。一次运行最多检查 500 个：

Shell

curl https://lovelyrouter.com/v1/tools/email-verify/run \
  -H "Authorization: Bearer $LOVELY_API_KEY" \
  -H "content-type: application/json" \
  -d '{
    "input": {
      "emails": ["hello@example.com", "nobody.here@example.com"]
    },
    "max_results": 2
  }'
