Platform Overview ​

Fast-API is an efficient AI large model API relay service platform operated by Jiuxi Limited. We are committed to providing high-quality API access services, making it easy for you to integrate advanced AI models into your products and services.

What is an AI API Relay Station? ​

An AI API relay station is a service platform that aggregates, unifies, and forwards AI interface calls. Developers do not need to connect to multiple vendors APIs separately; they can call different models and services through the relay station.

Core Advantages ​

1. Unified Interface Standards ​

Each large model provider (such as OpenAI, Anthropic, Google, etc.) has different API parameters. The relay station standardizes different interfaces, so developers only need to learn one specification.

2. Improved Access Stability ​

The relay station deploys global acceleration and load balancing to ensure your requests are more stable and smooth.

3. Unified Billing Management ​

The relay station supports unified billing and recharge, lowering the threshold for use.

4. Support for Multi-Model Switching ​

Quickly switch and call different models within a single API, greatly improving development efficiency.

Mainstream Model Support ​

The platform supports dozens of mainstream models such as GPT, Claude, Gemini, DeepSeek, covering text, image, speech, and other multi-modal scenarios. For the full list of supported models, please log in to the platform and view the model pricing page.

Application Scenarios ​

  • Individual Developers: Quickly experience different models without having to register on multiple platforms
  • Enterprise Applications: Use multiple models in different business scenarios, reducing operation and maintenance costs
  • Startup Teams: Rapidly validate product prototypes
