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.

Integrate in minutes

  1. Sign up and enroll authenticator MFA
  2. Create a test key — mock responses, no OpenAI cost
  3. Switch to a live key and add prepaid credit
  4. POST a frame to https://horusengine.fly.dev/v1/analyze

Pricing

Pay-as-you-go — no subscription tiers or bundled free scans. Test keys are free. Live scans deduct from prepaid balance per request (typically $0.015–$0.03 depending on mode and detail level).

Top up $5–$100 via Stripe Checkout. Usage and spend limits visible in the developer dashboard.

For integrators — not a consumer app

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.
