APIMaster is an AI API marketplace offering OpenAI, Claude, and DeepSeek API keys at up to 90% off official pricing. One API key gives you access to all major models with OpenAI-compatible endpoints โ€” plug directly into Cursor, Claude Code, or any SDK.

Every provider is fingerprint-verified weekly to ensure you're getting the real model. Supports PayPal, USDT, and ePay. No subscription, pay-as-you-go from $1.

Cubic features and specs

  • User-Friendly Interface
    Cubic provides a straightforward and intuitive interface, making it accessible even for users with limited experience in creating or customizing Linux ISOs.
  • Customizability
    Cubic allows users to easily customize Ubuntu-based distributions by installing software, tweaking settings, and adding files directly into the ISO image.
  • Real-time Preview
    The application provides a real-time preview of the ISO being customized, helping users to visualize the final product and make adjustments as necessary.
  • Enhanced Control Over Packages
    Cubic facilitates easy manipulation of package lists, including the ability to add, remove, or enable specific repositories for package installation.

Possible disadvantages of Cubic

  • Limited to Ubuntu-based Distributions
    Cubic is specifically designed for customizing Ubuntu and its derivatives, meaning it is not suitable for other Linux distributions.
  • Requires Linux Knowledge
    Despite its user-friendly interface, Cubic still requires a basic understanding of Linux commands and environment to make effective customizations.
  • Dependency on Ubuntu Packages
    Customizations are reliant on packages available within Ubuntuโ€™s repositories, which may limit the scope of modifications for users who require non-Ubuntu packages.
  • Performance and Resource Limitations
    Running Cubic can be resource-intensive, requiring significant CPU and memory usage, especially during intensive operations like large package installs or complex customization scripts.

  • Provider Leaderboard
    Real-time rankings by model authenticity โ€” see which providers pass or fail fingerprint checks

Questions & Answers

As answered by people managing Cubic and APIMaster.

Which are the primary technologies used for building your product?

APIMaster's answer:

Next.js, Go, Python (Flask), PostgreSQL

What makes your product unique?

APIMaster's answer:

Fingerprint verification โ€” we test every provider weekly using behavioral fingerprinting to detect model substitution. You can see which providers serve real models vs fake substitutes on our public leaderboard. No other API marketplace does this.

Why should a person choose your product over its competitors?

APIMaster's answer:

APIMaster is the only marketplace that verifies what model you're actually getting. Competitors like OpenRouter route traffic without verification โ€” you might pay for Claude Opus but receive a cheaper model. APIMaster detects this and only recommends verified providers. Plus, prices are up to 90% off official rates โ€” you get both cost savings and model authenticity guaranteed.

How would you describe the primary audience of your product?

APIMaster's answer:

Developers who use OpenAI, Claude, or DeepSeek APIs and want to reduce costs without sacrificing model quality. Especially useful for developers in markets where direct API access is expensive or restricted.

What's the story behind your product?

APIMaster's answer:

Built after discovering that many cheap API resellers secretly substitute expensive models with cheaper ones. We built fingerprint detection first, then a marketplace that only lists providers that pass verification.
