Is there a free Thor test network API?

[wupeaking]

Hi,
I'm coming too.
I am trying to make a system that scans the code for vechain payment.
You can fill in the payment information on the website website to generate the payment QR code.
Then use the APP to trade. My entire project at github is still in development, but I can already transfer money between my currency and ERC20 on the test network.
  The entire backend code has been deployed on my personal ECS. But I do not have more money to buy an ECS Synchronized Thor data, I would like to ask if there is a free API node available. I hope to get official support.

我正在尝试做一个扫码进行唯链支付的系统。
你可以在网站上 (https://wupengxin.cn/vechain_helper) 填入收款信息生成支付二维码。 然后使用APP进行交易。我的整个项目位于https://github.com/wupeaking/vechain_helper 目前还在开发阶段， 但是已经可以在测试网络进行本币和ERC20的转账交易。
目前已经在我的个人ECS上部署了整个后端代码。 但是因为穷没有更多的钱去买一个ECS同步Thor的数据， 因此想问官方是否有免费的API节点提供。 期望能得到官方的支持。

@wupeaking There is a MainNet public node: https://vethor-pubnode.digonchain.com, but no TestNet nodes
