GPT-5.6, Claude 5, Gemini 3 and Grok 4.5 — around 20% of official API prices
I built Mustham API for developers who want to use the latest AI models without constantly worrying about API costs.
Through one account, you can access:
GPT-5.6
Claude Opus 5 and Sonnet 5
Gemini 3.1 Pro and Gemini 3 Flash
Grok 4.5
Choose the model and route you want, create an API key, and connect it to tools such as Codex, Claude Code, Cursor, VS Code, or your own applications.
For most routes, pricing is around 20% of the corresponding official API price.
The lower price comes from combining coding capacity from multiple membership accounts into a shared pool, allowing unused capacity to serve other developers.
The model shown on the platform is the model you use. We do not secretly replace it with a cheaper model.
