Apertis

Apertis (by STIMA AI LLC) is an AI control plane that gives developers a single API key to access 30+ providers and 500+ models across coding agents and AI applications. It provides virtual keys, budget enforcement, prompt caching, intelligent fallback routing, and usage attribution so teams can manage spend and reliability across multiple LLM providers from one place. Instead of juggling separate API keys and billing for OpenAI, Anthropic, Google, and other providers, developers route all requests through Apertis, which handles provider failover and tracks usage per key or team.
