**APIs profiled:** 3

Martian operates an LLM model router and gateway that dynamically routes each request to the best underlying model across providers for the optimal balance of quality, latency, and cost. The Martian Gateway exposes a drop-in, OpenAI-compatible REST API (and an Anthropic Messages-compatible surface) so applications can route across a large catalog of models by changing only the base URL.
