Developer API
A semantic reasoning layer for robotics and camera-based apps
HorusEngine turns still camera frames into structured, TTS-ready JSON — scene context, object identification, and find-by-name search. Built for robotics teams (alongside local sensors), kiosks, and user-triggered camera workflows. Stateless. Pay-as-you-go. Optional frame correlation headers for multi-sensor integrators.
Scene context modes
Structured spatial descriptions from a still image — informational only, not physical navigation.
obstacles
Foreground / path-area object context — informational, not a safety alarm
nearby
Landmarks, crowds, and scene context beyond the immediate area
social
People, groups, and queues in the scene
full
Balanced on-demand scene description
Task modes
Analysis and output — identify objects or find named targets in the frame.
identify
Name foreground objects in the frame
find
Locate exits, restrooms, signs, and other named targets
Robotics & multi-sensor fusion
LiDAR, radar, or sonar handle real-time distance, collision avoidance, and emergency stops locally. HorusEngine adds semantic context on RGB — what is in the scene, not how far. Your safety loop never depends on the API.
Built for sensor fusion pipelines
Stateless doesn't mean disconnected. Pass correlation metadata on the way in; get it back on the way out.

HorusEngine is infrastructure for integrators. You build the client — TTS loop, UI, haptics, and safety policies. We do not store images or session memory. Integrators are responsible for end-user suitability and regulatory posture for their product.
AI outputs are probabilistic and may be inaccurate, incomplete, or delayed. HorusEngine is not intended for safety-critical use, real-time navigation, walking guidance for blind or visually impaired users, or medical applications. For robotics, deterministic local sensors must handle real-time obstacle mitigation and emergency stops. Integrators must validate all outputs and design end-user safeguards.
