## Frequently asked questions

### What is Apertis?

Apertis is an AI control plane for coding agents and AI apps. It gives teams one governed API path across 30+ AI model providers, plus virtual keys for issuing controlled access per team or agent, budgets and model policy to keep usage inside spending and model-access boundaries, routing and failover across providers, prompt cache to cut repeated-context cost on coding workflows, and drop-in integration — keep your SDK and change only the base URL.

### Which AI models and providers does Apertis support?

30+ providers and hundreds of models: OpenAI, Anthropic, Google (Gemini + Vertex), AWS Bedrock, Mistral, DeepSeek, Alibaba (Qwen), Moonshot, Zhipu (GLM), xAI, Together, and Groq. Coverage includes chat, embeddings, images, speech, and audio transcription. The current model list is browsable at https://apertis.ai/models.

### Which SDKs can I use with Apertis?

Apertis supports multiple SDK surfaces: OpenAI-format clients for /v1/chat/completions, /v1/responses, /v1/embeddings, /v1/images/generations, and /v1/audio/transcriptions; native Anthropic Messages at /v1/messages; direct HTTP; and the first-party Apertis SDK at https://github.com/apertis-ai/apertis-sdk for richer ergonomics over Apertis-specific features. Streaming, function calling, vision, and tool use all pass through.

### How does Apertis pricing work?

Two ways to pay, mix as you like. Subscription tiers are Lite at $12/mo, Pro at $25/mo, Plus at $60/mo, and Max at $200/mo — each with a defined quota for predictable monthly cost. Pay-as-you-go lets you top up credits and pay per million tokens at per-model rates, with no minimum spend. When a subscription quota is exhausted, requests fall back to PAYG credits with a hard cap you control, so a runaway agent loop won't drain your card. Full breakdown at https://apertis.ai/subscribe.

### How is Apertis different from OpenRouter / ZenMux / 9router?

Apertis uses paid multi-provider routes and does not depend on reusing consumer subscription OAuth tokens. It adds virtual keys, budgets, model policy, prompt cache, fallback, and request-level usage records around OpenAI-compatible and Anthropic API traffic. Model and route availability still depends on provider policy, region, account configuration, and the selected model. Apertis is operated by STIMA AI LLC; current product and setup details are available at https://docs.apertis.ai.

### Is Apertis safe to use with Hermes Agent / OpenCode / Claude Code / Kilo Code / Cursor / Cline?

Hermes Agent, OpenCode, Claude Code, Kilo Code, Cursor, and Cline can connect when the installed version supports a custom OpenAI-compatible or Anthropic endpoint. Configuration and supported capabilities vary by agent version and selected model, so use the current setup guides at https://docs.apertis.ai/installation and test the required tools, streaming, and model features before production use.
