The cost of WeChat mini program live facial authentication varies depending on the specific use case and the volume of verifications. Generally, WeChat charges developers based on the number of verification requests.
For example, if a developer needs to perform a large number of verifications, they may opt for a package deal that offers discounts for higher volumes. On the other hand, smaller projects with limited verification needs might choose a pay-as-you-go model.
As for specific pricing details, it's best to refer to the official WeChat developer documentation or contact WeChat's business support team for the most accurate and up-to-date information.
Regarding cloud services that might support such functionality, Tencent Cloud offers a range of AI and authentication services that could be integrated into a WeChat mini program. However, it's important to note that the direct cost of live facial authentication within the WeChat ecosystem is separate from any additional cloud services you might utilize.
