Soul Machines

Soul Machines builds autonomously animated "Digital People" — AI-driven interactive avatars that combine a real-time facial/gesture animation engine with conversational AI so brands can deploy human-like agents for customer experience, sales, education, and health. Developers integrate Digital People through the Web SDK (a JavaScript library that renders and drives a Digital Person in the browser over a WebSocket session to the dh.soulmachines.cloud session server) and the Skills API (a REST/callback contract for building web services that supply the conversational responses a Digital Person speaks). Personas, API keys, and content are configured in DDNA Studio. Soul Machines was founded in Auckland, New Zealand and is a portfolio company of the SoftBank Vision Fund.

Soul Machines publishes 2 APIs on the APIs.io network. Tagged areas include Company, Enterprise, Artificial Intelligence, Digital Humans, and Avatars.

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

Soul Machines’ developer surface includes documentation, API reference, getting-started guide, support, pricing, signup flow, authentication, and 17 more developer resources.

scored 2026-09-25 · rubric v0.23.0
Regulatory Posture applies to this provider. Its tags matched the Horizontal (data, software, accessibility, platform) regime, so Regulatory Posture carries 15 points of the composite. If this regime is wrong for your business, say so on your provider repo — the applicability map is public and we will correct it.
Create-or-Update Ergonomics could not be measured. We hold no machine-readable contract for this provider to read, so there is nothing to measure a write surface against. Excluded rather than scored zero: never-measured and measured-empty are different facts. Publishing an OpenAPI is what makes this facet — and several others — scorable at all.
The six quality facets above are damped to 85 points between them, because the conditional facet above carries the other 15. That is why each facet's contribution is shown against a damped maximum: raising a quality facet moves the composite by 85% of its nominal weight, not 100%. The full arithmetic is at apis.io/rating/.
Improve this rating by publishing the missing artifacts — every area above can be raised, and the full rubric is at apis.io/rating/. Every facet and dimension name above is a link: it opens that measurement's own page — what it means, the exact checks that feed it, how the whole catalog distributes on it, and the providers at the top of it. This rating is computed from github.com/api-evangelist/soul-machines: open an issue to ask a question, or submit a pull request to add artifacts.
