# Affectiva

> Emotion AI out of the MIT Media Lab, headquartered in Boston. Affectiva's AFFDEX science
> measures emotion, attention and cognitive state from spontaneous facial expressions and
> speech, trained on 17.4M face videos and 8B facial frames from 90 countries. Sold into
> media analytics (ad and entertainment content testing, qualitative research), in-cabin
> automotive driver and occupant monitoring, and academic behavioral research. Acquired by
> Smart Eye AB in 2021; the commercial product line has since been folded into the iMotions
> brand, and www.affectiva.com now 301s its product, solutions and contact pages to
> imotions.com.

## What Affectiva does not publish

Recorded so an agent does not go looking: no OpenAPI 3.x (the contracts are Swagger 2.0), no
GraphQL, no MCP server, no A2A agent card, no AsyncAPI or webhook catalog, no security.txt,
no /.well-known documents of any kind, no status page (status.affectiva.com does not
resolve), no changelog, no CLI, no public pricing or plans, no documented rate limits, no
idempotency mechanism, no reversal or undo operation for any of its 33 write operations, and
no pagination on any collection endpoint. The former documentation hub
knowledge.affectiva.com now returns a readme.io "Not Yet Active" placeholder, and both
developer.affectiva.com and auto.affectiva.com redirect to an Atlassian Confluence login.
