What is Mesh API?
Mesh API is a unified LLM gateway giving access to 1,000+ models from OpenAI, Anthropic, Google, Meta, Mistral, DeepSeek, Alibaba, and other providers through a single Router Service Key. It is a drop-in OpenAI-compatible replacement - you only change the base_url and API key - and adds zero-downtime failover across providers, response caching, and per-key spend controls with no platform markup on its pay-as-you-go plan.
