**APIs profiled:** 5

Spline is a real-time collaborative 3D design tool with AI-driven object generation, web embedding, and animation. Spline does NOT publish a REST API for 3D scene generation as of May 2026; instead it exposes Code APIs (Web, SwiftUI, Kotlin) for embedding scenes, plus a real-time API for variables/data and webhooks for event-driven integrations.
