Sublyx is an AI API aggregation gateway that provides a unified entry point for multiple model providers including OpenAI, Claude, and Gemini.
What is Sublyx?
Sublyx is an AI API aggregation gateway that provides a unified interface for accessing multiple Large Language Model (LLM) APIs such as OpenAI, Claude, and Gemini. It takes API requests from clients and routes them to the appropriate upstream provider, returning the model's response. Sublyx is a cloud-based platform offered by an unspecified maker (the page does not state the company name). It aims to simplify integration and reduce the overhead of managing multiple API keys and billing accounts.

How does Sublyx work?
To start, register on the Sublyx console to obtain an API key. Then configure your client's Base URL and API key to point to Sublyx's endpoint. All requests are then routed through Sublyx to the specified model provider. The console provides usage monitoring and credential management.
Pricing
Sublyx offers a free Starter tier (¥0/month) with basic capabilities, a Pro tier with usage-based billing and higher concurrency limits, and an Enterprise tier with custom deployment options and SLA guarantees.
FAQ
What providers does Sublyx support?
Sublyx supports OpenAI, Claude, Gemini, and other major model ecosystems, with the full list available in the console and documentation.
Can I use Sublyx in production?
Yes. Sublyx is designed for production use, with configurable rate limiting, auditing, alerts, and key management strategies.
What is the difference between Sublyx and using official APIs directly?
Sublyx acts as a unified gateway, so you only need one API key and one account to access multiple model services, instead of maintaining separate keys and billing for each provider.
Does Sublyx support client tools like Claude Code or Cherry Studio?
Yes. Sublyx provides OpenAI-compatible and Anthropic Messages-compatible endpoints, enabling integration with tools like Claude Code, Codex, Cherry Studio, and standard OpenAI SDKs.
How do I handle API key leaks?
API keys are displayed only once at creation. If lost or compromised, revoke the key in the console and generate a new one immediately.
