Ex-Human
Ex-Human is a "Digital Human as a Service" platform that provides a single, unified API for building fully immersive, emotionally intelligent AI companions that communicate through text, voice, images, and video. Backed by a16z, the company lets developers design unique character personalities and generate multimodal responses at production scale. The Ex-Human API spans a multimodal chatbot (roleplay and realistic-chat models with long-term memory and smart replies), image generation (personalized gallery images and avatars via the persona-2 and supreme models), talking-head avatar animation (lip-sync from text or audio), image-to-video animation jobs, and text-to-speech. It is trusted by large consumer-technology companies to power AI companions, entertainment and gaming NPCs, dating experiences, AI twins, education tutors, and healthcare and therapy support at scale.
Real signal across most facets with visible, nameable gaps — the contract exists but is thin, or the portal is good while governance and commercial terms are absent.
API Evangelist profiles Ex-Human the way a machine reads it — 8 machine-readable artifacts across 4 APIs, pulled from the provider's own public surface and indexed so a developer, an analyst, or an AI agent can evaluate it against every other provider on the network.
Every provider in the network is reduced to the same set of machine-readable artifacts — OpenAPI contracts, event specifications, GraphQL schemas, runnable collections, pricing and rate-limit signals, security posture, OAuth scopes, and the agent surfaces (MCP servers and skills) that let software drive the API on its own. We profile them because the interface is the part of a company you can actually inspect: it is a truer signal of what a provider does than any marketing page. From those artifacts we compute the Kin Score — Ex-Human scores 48.5/100 (developing), with a separate agent-readiness read of 65/100 (agent native). The full breakdown is below, followed by every artifact we hold — each card links through to its machine-readable definition on apis.io.
Kin Score
This is the API Evangelist rating — a single, repeatable read computed from the artifacts on this page. Green fill is points earned; the red track is points possible, so every bar shows earned-versus-possible at a glance.

How we profile Ex-Human
Each block below is one kind of artifact we hold for Ex-Human. For each we say what it is and why it earns a place in the profile, then list every one we've indexed — capped at two rows, scroll within the panel for the rest.
APIs 4
Each API is captured as its own OpenAPI definition — every operation, parameter, and response. This is the single most useful machine-readable description of what an API does, and it's what lets us score, lint, mock, and generate against it without asking the provider for anything.
Individual APIs this provider publishes, each with its own machine-readable definition.
Ex-Human animations API
The animations API from Ex-Human — 6 operation(s) for animations.
Ex-Human chatbot API
The chatbot API from Ex-Human — 3 operation(s) for chatbot.
Ex-Human Image Generation API
The Image Generation API from Ex-Human — 2 operation(s) for image generation.
Ex-Human Text to Speech API
The Text to Speech API from Ex-Human — 1 operation(s) for text to speech.
MCP Servers 1
Model Context Protocol servers expose these APIs directly to AI agents. We profile them because agent-native access is the fastest-growing way this provider's capabilities actually get used.

MCP SERVERSecurity Posture 2
Authentication, domain security, vulnerability disclosure, and trust-center signals — the evidence that a provider takes security seriously enough to document it. We profile it because you can't govern what you can't see.
Authentication, domain security, vulnerability disclosure, and trust-center signals.
Agentic Access 1
An x-agentic-access contract marks which operations are safe for an agent to run on its own and which need a human in the loop. It is the difference between an API an agent can use and one it can use safely.
