What does AI API do?

AI API is a developer tool that acts as a single gateway to over 100 different AI models. Instead of managing separate API keys and integrations for OpenAI, Anthropic, Google, and others, you can connect to AI API once. It then routes your requests to the model you specify, handling all the provider-specific details behind the scenes. This means you can switch between models like GPT-5.4, Claude Opus, or Gemini Pro without rewriting your application's code.

The platform stands out by offering a fully OpenAI-compatible endpoint. You can use your existing OpenAI SDK code, simply change the base URL to AI API's, and start making calls. It promises significant cost savings, advertising discounts of up to 50% off standard rates for major models. For reliability, it includes features like automatic failover, load balancing, and a 99.9% uptime SLA, aiming to be robust enough for production applications.

This tool is built for developers and teams who are already using or want to experiment with multiple large language models. It's particularly useful for SaaS companies building AI-powered features like chatbots or content generators, tech teams creating internal coding assistants, and product managers who want the flexibility to test different models without a complex integration process. It removes the headache of managing multiple vendor relationships and simplifies billing and monitoring into one dashboard.
