Why DeepSeek Through Token Gateway?
PayPal Payment — No Chinese Phone Required
The biggest barrier to using DeepSeek directly is the Chinese registration process: you need a Chinese phone number for SMS verification, and payment requires WeChat Pay or Alipay. Token Gateway removes both obstacles. Pay with your PayPal account and get an API key instantly.
OpenAI-Compatible API
No SDK changes needed. Just swap the base URL and API key:
# Before (OpenAI)
client = OpenAI(api_key="sk-openai...")
# After (Token Gateway)
client = OpenAI(
api_key="tg-...",
base_url="https://token.mall199.com/v1"
