Our engineers are integrating with your APIs and we meet some problems. Could you please help to to check how to solve these problems?

Model parameter error or insufficient credit/quota. Did the https://api.vapi.ai/chat interface return nothing? Also, the request timed out.

The response from https://api.vapi.ai/chat is too long and contains too much irrelevant content. How can I debug this?

The response from https://api.vapi.ai/chat is too slow; it takes 10 seconds to reply. Using Provider: openrouter, Model: mistralai/mistral-large. Business flow: Client → Backend → /chat API request, waiting for /chat API response.

Do you have technical support teams that can answer our questions?

Looking forward to hearing from you.

Thank you!
