## What agents can do

- Help the user open the Zro website and navigate sign-up, sign-in, pricing, billing, and API key creation.
- Configure the user's local coding tool after the user provides or approves use of the generated API key.
- Use the existing inference API after setup.
- Cite the public technology, research, pricing, licensing, privacy, and terms pages when answering questions about Zro.

## Product facts

- Zro is operated by MoonMath.ai.
- Zro serves open-weight coding models through OpenAI-compatible and Anthropic-compatible APIs.
- Zro does not retain prompt or completion bodies after processing.
- Zro does not use customer prompts or completions for training, fine-tuning, evaluations, analytics, or dataset creation.
- Model inference can be restricted by API key to Europe, the United States, or either region.
- Pricing, supported models, and regional availability can change; use the linked live pages for current details.

## User-controlled steps

- Account sign-up and sign-in are user account actions.
- Billing and payment approval must be completed by the user.
- API keys are sensitive. Do not store a key except in the local tool configuration the user requested.
