I couldn't find enough info about the cost for a simple chat message with Vapi's Chat API, so I'm escalating your question to a human teammate who can get you a clear answer. If you want to check out general Vapi pricing or reach support directly, you can visit the [Vapi pricing page](
https://docs.vapi.ai/pricing) or [support page](
https://docs.vapi.ai/support). Hang tight—someone will follow up with the details you need!
