I built an API for GPT, Claude, Gemini & Grok at 50% or less of official pricing

Hi everyone! I’m an indie developer, and AI API costs were becoming one of the biggest expenses in my projects—especially during coding, debugging, research, and repeated testing.

So I built Mustham API, a multi-model API platform that provides access to:

GPT，Claude，Gemini，Grok

You can choose the specific model and route you want instead of having different sources silently mixed together. Many routes are priced at less than half of the corresponding official API price.

The platform also provides direct support. If you encounter problems with integration, streaming, latency, stability, or model configuration, we will help investigate them.

I’m especially looking for feedback from developers using real coding workflows, including Cursor, Claude Code, Codex, VS Code, agents, and custom applications.

Please tell me honestly what works and what needs improvement. If you find the service useful and later decide to become a paying customer, I would be genuinely grateful for your support.
