Model	DeepSeek V4 Pro	GPT-4o	DeepSeek V4 Pro
Input Price / 1M	$0.28	$2.50	$0.28
Output Price / 1M	$0.56	$10.00	$0.56

Local Payment	Card + MoMo soon	Card only	Alipay/WeChat
OpenAI Compatible	100%	Native	Partial

Why not use DeepSeek directly?

• DeepSeek blocks IPs from Vietnam and most of Southeast Asia — you need a VPN
• Only accepts Alipay/WeChat Pay — no support for Vietnamese cards or MoMo
• API format differs slightly from OpenAI — requires code changes
• High latency from Vietnam via VPN through China
• KYC requires Chinese ID — impossible for most SEA developers

How NexAPI solves this

International card payments + MoMo coming soon
100% OpenAI API compatible — existing code works immediately
Dashboard with usage tracking, API keys, billing
No Chinese KYC — just email signup
