// Contact

Talk to ARCANA.

Use this page as the public contact point for ARCANA and OTNEL. For product questions, enterprise evaluation, commercial discussions, account or billing questions, documentation corrections, or security-related coordination, email [email protected]. Include enough context to route the request: the ARCANA surface involved, the expected behavior, what happened instead, and whether the issue affects the website, CLI/TUI, proxy, authentication, billing, or another documented component.

Support and technical questions

Before reporting a technical problem, check the developer documentation and service status. API integrations should reference the current OpenAPI specification. If the problem is reproducible, include the relevant command or endpoint, HTTP status or error code, and a minimal reproduction that does not contain provider keys, access tokens, passwords, private repository contents, or other secrets.

Commercial inquiries

For Enterprise evaluation, describe the intended deployment, team size, required integration surfaces, and any audit, synchronization, gateway, or support requirements. Current public plan information remains on the pricing page; custom Enterprise terms should be confirmed directly rather than inferred from cached pages or third-party summaries.

Automated clients

Agents and crawlers can use llms.txt, agents.md, the sitemap, and the API catalog for machine-readable discovery.
