Emotion Detection API

Emotion Detection API

Arya.ai’s Emotion Detection API empowers businesses to understand customer feelings the moment they appear on screen. Leveraging state‑of‑the‑art computer‑vision models, it reads facial expressions in live video or images and returns actionable emotion scores—so agents, apps, and analytics tools can instantly adapt, personalize, and delight.
Emotion Detection API

The Emotion Detection API is a lightweight, RESTful service that detects and classifies emotions (e.g., happiness, surprise, anger, neutral, sadness, fear, disgust) from faces in real time.

  • Multi‑format input: Works with live video streams (RTSP, WebRTC) and images (JPG, PNG).
  • JSON output: Returns per‑face emotion labels, confidence scores, bounding‑box coordinates, and aggregate sentiment metrics.
  • Privacy by design: No images are stored; all inference happens in secure environments, meeting compliance requirements.
  • Customer‑Service Platforms

Guide agents with on‑screen cues when frustration spikes.

  • Retail & Hospitality

Measure in‑store sentiment, optimize queue management, and boost staff responsiveness.

  • UX & Product Teams

A/B test experiences and content by tracking real‑time emotional engagement.

Send frames or images via API endpoint. The model detects faces, analyzes micro‑expressions, and classifies dominant emotions. Receive JSON with time‑stamped emotion scores and optional aggregate sentiment.

  • Input: JPG, PNG, MP4 frame grabs, RTSP / WebRTC video frames
  • Output: Structured JSON (emotion label, confidence, face box, timestamp, aggregate sentiment)
