I Built a Zero-Markup AI API Gateway – 제공자 비용으로 18개 모델

The Problem

Every AI API gateway I tried added an invisible margin. OpenRouter, the biggest player, quietly marks up every model. You pay more than the provider charges, and you don’t even know how much.

The Solution

I built aipossword.cn — an open-source AI API gateway with zero markup pricing.

• 18 models across DeepSeek, Claude, Qwen
• Zero markup — you pay exactly what providers charge
• One endpoint — OpenAI compatible, one line code change
• Open source — AGPLv3, built on New API (18k+ GitHub stars)
• Free $5 credits on signup

Model Pricing

Why I Built This

I got tired of paying hidden fees on every API call. So I forked New API (18k stars), connected 18 models, and set markup to zero.

Is zero markup sustainable? I think the answer is yes — if enterprise users pay for SSO, SLA, and dedicated infrastructure. Individual developers get it free, at cost.
