**APIs profiled:** 6

LangDB is an AI gateway and governance platform that routes requests across 250+ models from providers such as OpenAI, Anthropic, Google, Meta, Mistral, and DeepSeek through a single project-scoped, OpenAI-compatible REST API. It layers routing, guardrails, tracing, cost control, and an MCP (Model Context Protocol) gateway on top of that unified interface.
