Agora/Zegocloud Session Integration for Chat/Call

"Only For Individual Developers. Not For Company" I have integrated Zegocloud / Agora API for Audio/Video Calling and Chat. The Chat and Calling will be done on the per minute basis. For Example :- A user has ₹50 in his wallet. Amount set for chat / call : ₹10 per minute. If a user start chat or call us for 1 min then according to the set amount (say ₹10 per minute), the user Chat / Call should max last for 5 minutes (as the user has ₹50 in his wallet) and as soon as 5 min gets complete, the chat/call will get disconnect and from the user wallet ₹50 will be deducted. The session will be created between user and admin during the chat or call, after which the chat or call should end automatically (if not ended from user side or admin side). I am unable to create the session successfully. It's giving errors. So I need help in creating this session. I'm looking for a skilled developer who can help me create a versatile chat and audio/video calling platform. I need this platform to be highly adaptive, supporting both one-on-one and group sessions. The system should charge users on a per-minute basis. This is particularly crucial for my business model. Additional Features: - The ability for users to share files during the session - A screen sharing function - this is essential for my online tutoring business - Live note-taking feature for future reference I'm specifically interested in using Agora or Zegocloud for my platform, so experience with these technologies would be a huge plus. Ideal skills and experience for this project include: - Proficiency in Agora/Zegocloud or similar real-time communication APIs - An understanding of payment integration for charging on a per-minute basis - Experience in creating chat platforms - Proficiency in integrating additional features such as file sharing, screen sharing, and live note-taking.
