About AnnexAPI
AnnexAPI provides a single endpoint for accessing multiple AI model providers including OpenAI, Anthropic, Qwen, GLM, Kimi, Grok, DeepSeek, and Gemini. The service automatically routes each request to the cheapest available provider that supports the requested model, optimizing costs without manual intervention. Usage is billed in US dollars with five-decimal precision, charging only for consumed tokens with no monthly fees or seat requirements. The platform includes continuous health checks on providers, automatically failing over to alternative routes when degradation is detected to maintain 99.9% uptime. For models supporting prompt caching, cache reads are billed at reduced rates, making long system prompts more economical. The service offers comparative pricing analysis showing significant cost reductions compared to standard provider rates across various models.
