No CoT message schema or plugin manifest is published. - FUSE topside protocol: the FUSE page states "Open source protocol for pushing results into custom topside applications." No specification, schema or repository for that protocol could be found. - PARse "configurable ingest": accepts a customer element data format. The format is not documented publicly. - INStinct aiding-source interface: "provides a straightforward interface to integrate other sensors." No interface control document is published publicly. - Fathom: a browser-based configurator that connects to the vehicle. No HTTP API is documented and no host for it resolves publicly. ## What does NOT exist (probed 2026-09-02, every path returned 404) - No OpenAPI, Swagger, GraphQL SDL, AsyncAPI, Protobuf or WSDL. - No developer portal, API reference, or docs host. api./docs./developer./developers./app./portal./ status./mcp.vatn.com all fail to resolve (NXDOMAIN). - No /.well-known/ documents: security.txt, openid-configuration, oauth-authorization-server, oauth-protected-resource, api-catalog, ai-plugin.json, agent-card.json and agent.json all 404. - No MCP server, no A2A agent card, no llms.txt. - No SDKs or client libraries on npm, PyPI, or any other registry. - No public repositories: github.com/Vatn-Systems exists (created 2023-10-02) but is empty. - No pricing or plans page; no sign-up. Sales is a demo request or a supplier form. - No status page, changelog, deprecation policy, or vulnerability-disclosure program. - The footer's Privacy Policy, Terms & Conditions and Accessibility Statement links are href="#" placeholders, not documents. ## Company - Website: https://www.vatn.com/ (vatnsystems.com redirects here) - About: https://www.vatn.com/about - News: https://www.vatn.com/news - Careers: https://www.vatn.com/careers - Contact: https://www.vatn.com/contact - Become a Supplier: https://docs.google.com/forms/d/e/1FAIpQLSfBzL8z1SItEYcmy-FSdYKFE7Bk5E-6jS-8bDTRwHnGWJvI-Q/viewform - GitHub: https://github.com/Vatn-Systems (0 public repositories) - LinkedIn: https://www.linkedin.com/company/vatnsystems/ - X: https://x.com/vatnsystems Founded 2023 by Nelson Mills (CEO), Freddie Mills, Geoff Manchester (CTO) and Dan Hendrix. Based at 500 Wood St., Bristol, RI 02809. Raised a $13M seed (Nov 2024) and a $60M Series A (Dec 2025), total funding $76.5M. Acquired Crewless Marine. Production facility in Bristol rated to roughly 2,000 units per year. ## How to reach Vatn Systems as a machine You cannot. There is no programmatic surface. Every path to Vatn's technology runs through a human: "request capability brief", "Request a Demo", "Contact Sales", or the Become a Supplier form.
