Sharing: Alternative API access for developers without international credit cards

Hi community,

Sharing a solution we've been working on for developers who can't access LLM APIs due to payment restrictions:

The Problem: Most LLM API platforms (OpenAI, Anthropic, etc.) require Visa/Mastercard. Developers in Southeast/South Asia often can't pay.

Our Approach:

• OpenAI-compatible API proxy (swap your base_url, keep everything else)
• Payment via Wise bank transfer (USD, no credit card required)
• Starting with DeepSeek models, expanding to more providers

Quick Start:

import openai
client = openai.OpenAI(
    api_key="your-yingsuan-key",
    base_url="https://yingsuan.top/v1"
)
response = client.chat.completions.create(
    model="deepseek-chat",
    messages=[{"role": "user", "content": "Hello!"}]
)

Full docs: yingsuan.top/api | GitHub

Would love feedback on what other models/regions developers need most.

No FastChat file, test, or entry point is identified. First clarify whether this external API proxy is intended to change FastChat and define the requested integration, affected models or regions, and acceptance criteria before starting work.
