SpAItial

SpAItial is a frontier AI lab building physically-grounded world models. Its Echo model turns a single image, a 360-degree panorama, or a text prompt into a persistent, explorable 3D Gaussian Splat world. The SpAItial Developer API is a REST interface for generating, editing, exporting, and downloading these 3D worlds programmatically. Generation is asynchronous (submit a job, then poll or receive a webhook), authenticated with bearer API keys carrying explicit scopes, metered in credits, protected by per-key rate limits and an Idempotency-Key contract, and fully agent-ready through a hosted Model Context Protocol (MCP) server and a published Agent Skill.

SpAItial publishes 4 APIs on the APIs.io network, including files API, models API, panoramas API, and 1 more. Tagged areas include Company, World Models, Spatial AI, 3D World Generation, and Gaussian Splatting.

The SpAItial catalog on APIs.io includes 1 event-driven AsyncAPI specification.

SpAItial’s developer surface includes authentication, documentation, API reference, getting-started guide, engineering blog, pricing, signup flow, and 27 more developer resources.
