# Beacon Biosignals > Neurotechnology company applying machine learning to EEG to advance precision medicine for conditions affecting the brain. Beacon operates a life-sciences platform for EEG in drug development and clinical trials, and a home sleep testing business (SleepView Monitor, SleepView Direct, Waveband/Dreem 3S). Beacon publishes NO public REST API and NO developer portal — its public technical surface is an open-source Julia ecosystem. Generated by the API Evangelist enrichment pipeline on 2026-07-20 from apis.yml and the artifacts in this repository. Beacon does not publish its own /llms.txt (https://beacon.bio/llms.txt returns 404), so this file is GENERATED, not harvested. ## Important for agents - There is no public Beacon API. Do not attempt to construct API calls against beacon.bio. - api.beacon.bio and developer.beacon.bio do not resolve. docs.beacon.bio is a PRIVATE GitHub Pages site behind GitHub authentication and is not public documentation. - app.beacon.bio is the SleepView customer portal. It is a single-page application that returns HTTP 200 with an HTML shell for EVERY path, including /openapi.json and /.well-known/*. Those responses are a catch-all, not real artifacts — treat them as 404. - Integration with Beacon is a commercial conversation, not a self-serve signup.
