Hotmail
Hotmail was one of the first free web-based email services, launched in 1996 by Sabeer Bhatia and Jack Smith and among the earliest venture-backed consumer web companies (funded by Draper Fisher Jurvetson and Menlo Ventures). Microsoft acquired Hotmail in December 1997 and operated it as MSN Hotmail and later Windows Live Hotmail. In 2013 Microsoft folded Hotmail into Outlook.com; hotmail.com mailboxes remain fully active but are served by Outlook.com and Microsoft 365 infrastructure. Hotmail exists today only as a legacy consumer email brand and domain, with no standalone developer program. Programmatic access to hotmail.com mailboxes is provided through Microsoft Graph (Outlook Mail) and the standard IMAP, POP, and SMTP protocols, not a dedicated Hotmail API.
Index entry only — little beyond a description and a link, and nothing machine-readable enough for an agent to act on without a human reading the site first.
API Evangelist profiles Hotmail the way a machine reads it — 1 machine-readable artifact, 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 — Hotmail scores 6.8/100 (minimal), with a separate agent-readiness read of 0/100 (human only). 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 Hotmail
Each block below is one kind of artifact we hold for Hotmail. 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.
Security Posture 1
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.
