Show HN：PlaceCall（YC W26）——让 Agent 致电商家并完成事务的 API

嗨，HN 的朋友们，我们是来自 VOYGR 的 Yarik 和 Vlad。我们正在为 Agent 和应用构建与本地商家互动的工具。

这一切始于 VOYGR 自身的痛点：致电商家确认它们是否营业。我们都来自 Google（Maps 和 Search），即使在那里，商家和场所也不会及时更新这些信息。因此，我们构建了一个 API，并开始在内部使用它。

7 月 4 日，我们驾车经过波特兰，想找个地方吃饭。Google Maps 显示“节假日营业时间可能有所变化”。我们试了一些 AI 助手应用（当时 Poke 正在流行），但它们帮不上忙。我们的 API 找到了 15 家泰餐和寿司店，并行拨打电话。其中几家确认当天营业，并且接受直接到店的顾客。有一家在 Google 上被标记为已关闭。应用可以找到餐厅，但仍需要有人接听电话。

这是我们不断遇到的问题。在现实世界中，电话号码仍然是重要的沟通接口，而助手能做的事情并不多。Muse 在 Beta 模式中加入了电话呼叫功能，但它仍然一次只能呼叫一家店。有很多工具可以让你创建自己的语音 Agent，但没有什么产品能够真正开箱即用。我们构建 PlaceCall，是为了满足你的各种 Agentic 需求。只需用自然语言提供一项任务，再提供一个美国电话号码（或号码列表），它就会导航电话菜单、在你等待接通时保持在线，并返回包含结果、录音和文字转录的结构化响应。如果你没有电话号码，只需描述你的需求，PlaceCall 会给出推荐。演示如下：视频/嵌入内容：PlaceCall 演示

在黑客松中测试 PlaceCall API 时，开发者实现了以下使用场景：确认医生是否接收新病人、获取汽车服务报价，以及进行快速问卷调查。该 API 可通过 Claude Code 和 Codex 使用；示例和配置说明列在仓库中：https://github.com/voygr-tech/placecall。我们提供前 250 通电话免费额度。产品页面在此：https://voygr.tech/placecall/

欢迎试用，并告诉我们使用体验。我们很想了解你会用它做什么，以及还缺少哪些能力。我们全天都会在这里，很乐意回答任何问题。我们的邮箱：founders@voygr.tech

Hi HN, this is Yarik and Vlad from VOYGR - we are building the tools for agents and apps to engage with local businesses.

It all started with our own pain point at VOYGR: calling businesses to verify if they are open. We are both from Google (Maps and Search) and even there, the merchants and venues don’t keep this info updated. So we built an API and started using it in-house.

On July 4th, we were driving through Portland looking for a place to eat. Google Maps was saying “Holiday hours may vary”. We tried some AI assistant apps (Poke was trending back then), and they couldn’t help. Our API found 15 Thai and sushi places and called it in parallel. A few confirmed that they are open today and are taking walk-ins. One was marked closed on Google. The app can find the restaurant, but someone has to answer the phone.

This is the problem we kept seeing. Assistants can’t do much in the real world where the phone number is still a major communication interface. Muse added calls in beta mode, but it’s still calling only one place at a time. There are a bunch of tools to create your own voice agents, but nothing that can work simply out of the box. We’ve built PlaceCall to fit all your agentic needs. Give it a task in plain English and a US phone number (or a list of numbers) - it navigates phone menus, waits for you on hold, and returns a structured response with outcome, recording and transcript. If you don’t have a phone number, just describe what you need and PlaceCall comes up with the recommendations. Here is the demo: https://youtu.be/7ZbVCPv8Wq0?si=LoLxxx1M7nhS7_j-

When PlaceCall API was tested in our hackathon, we had the following use cases implemented by the developers: checking if a doctor accepts new patients, getting quotes for car service, and running quick surveys. The API can be used through Claude Code and Codex; examples and setup are listed in the repo: https://github.com/voygr-tech/placecall We give the first 250 calls free.

Try it and let us know how it goes. We are interested in learning what you would use it for and what is missing. We are here all day and happy to answer any questions. Our email: founders@voygr.tech
