Mustham API

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.

I am currently giving new users free testing credits.

No payment information is required.

Then open the Community section and send us your username to receive the credit.

Try the latest models on a real project, compare the cost, and judge the results yourself.

Same leading models. Much lower cost. Free to test.

I originally built Mustham API to reduce the cost of my own AI coding workflow.

As a heavy user of AI coding tools, I noticed that membership accounts often include much more coding capacity than one person can fully use. Individual usage is uneven: some people leave a large amount of capacity unused, while others need significantly more.

Mustham API solves this by combining capacity from multiple accounts into a shared pool and making it available through one integrated API platform.

This allows developers to:

• Access leading AI models through one account

• Choose the model and route they prefer

• Generate API keys for their own tools and projects

• Continue using familiar OpenAI-compatible workflows

• Reduce AI coding costs significantly

For most of our routes, pricing is around 20% of the corresponding official API price.

We also provide routes connected directly to official API keys for users who prefer that option. These routes cost more, but are still managed through the same Mustham API account.

How can the price be lower?

The main advantage comes from improving capacity utilization.

A single developer may not fully use everything included with a membership account. By combining multiple accounts into a shared pool, unused capacity can be distributed across different users instead of being wasted.

The price users pay covers:

• Membership account costs

• Server and platform operation

• Account-pool maintenance

• Technical support

• Troubleshooting and continued development

This allows us to provide the same listed AI models at a much lower effective cost.

The model displayed on our platform is the model users receive. We do not secretly replace it with a cheaper model or downgrade requests to another model.

Free credits for real testing

I am currently looking for developers and small SaaS teams willing to test Mustham API with real workloads.

Free trial credits can be used to test:

• Model quality

• Coding performance

• Existing tool compatibility

• Concurrent requests

• Longer development workflows

• Documentation and setup

No payment information is required.

To receive free credits:

1. Register at https://api.mustham.com

2. Open the Community section

3. Join our Discord

4. Send your Mustham API username in the general channel

I will add the trial credit to your account.

Mustham API currently supports routes for Claude, Gemini, OpenAI and other major AI models, along with setup assistance for tools such as Claude Code, Codex, Cursor and VS Code.

I am building this for developers who want to use powerful AI models more frequently without paying the full official API price.
