AnnexAPI
One API for leading AI models at unbeatable prices
One OpenAI-compatible API for Claude, GPT, Gemini, DeepSeek, Grok and more. Price-aware routing, automatic failover, transparent USD billing, and pay-as-you-go pricing.
We built AnnexAPI to make working with multiple AI models simpler and more affordable.
Instead of integrating and managing different providers individually, developers can use one OpenAI-compatible API to access models from Claude, GPT, Gemini, DeepSeek, Grok and others.
AnnexAPI also includes price-aware routing and automatic failover to help handle provider availability and rate limits.
We're launching to get feedback from developers — especially around API compatibility, pricing, latency and reliability.
If you try it, we'd love to hear what works and what doesn't.
