Stream

Stream (GetStream.io) provides scalable, API-first infrastructure for in-app chat messaging, activity feeds, audio/video calling and livestreaming, and AI moderation. The server-side platform is a documented REST API (base https://chat.stream-io-api.com for Chat) with JWT authentication, complemented by client SDKs that open a persistent WebSocket connection to receive real-time events - message.new, typing.start, user.presence.changed, reaction.new, notification.* and periodic health.check heartbeats. Products are metered on monthly active users (Chat) and participant minutes (Video), with Free/Maker, Standard (Startup) and Enterprise tiers.

Stream publishes 18 API contracts indexed on the APIs.io network, including Product:common API, Product:feeds API, Product:moderation API, and 15 more. Tagged areas include Chat, Messaging, Activity Feeds, Video, and Audio.

The Stream catalog on APIs.io includes 2 event-driven AsyncAPI specifications and 1 Spectral governance ruleset.

Stream’s developer surface includes authentication, documentation, engineering blog, and 12 more developer resources.

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 applies to this provider. This API accepts writes, so it carries 10 points of the composite. It is scored from the published contracts themselves: whether a caller can create-or-update in one call, whether the write accepts a key the caller already holds, and whether the response says which branch ran. Without that, every write needs a search-and-branch in front of it, and the first time that check is skipped a duplicate record is created. Scored against the observed mean rather than raw — a provider at the catalog average is unchanged by this facet, not penalised by it.

The six quality facets above are damped to 75 points between them, because the conditional facet above carries the other 25. That is why each facet's contribution is shown against a damped maximum: raising a quality facet moves the composite by 75% of its nominal weight, not 100%. The full arithmetic is at apis.io/rating/.

Markets this provider is in provisional

The Kin Score Market layer reads a provider inside its market: its position, and how deep its integrations go. Depth is only comparable within a position. Provisional and unweighted: not part of the Kin Score or agent readiness.

Market	Position	Depth	Registered MCP server	Declares compatibility
Agent Skills (SKILL.md packages)	undeclared	-	-	1

Registered MCP server and declares compatibility are report only — not weighted. Undeclared means we found nothing we can read, so there is no number: we never infer integrations.

Standards implemented 2

Standards this provider implements or carries. De facto ones are profiled and measured by the API Commons; formal ones come from the standards directory and are linked by the provider's own tags. The evidence column says how each claim was established — not that it was made.
