InAuth (American Express)
InAuth is a mobile-first digital device intelligence and authentication company acquired by American Express in 2018 and now operated within American Express's fraud-management portfolio; its technology also powers Accertify Device Intelligence. The InAuth Security Platform provides persistent device identification (device fingerprinting), malware and criminal-tool detection, rooted/jailbroken-device detection, location and behavioral risk analysis, and transaction risk scoring, delivered primarily through native iOS and Android SDKs embedded in merchant and financial-institution apps. Access is enterprise-gated through the Amex for Developers portal; there is no public self-serve REST API, OpenAPI specification, public package-registry distribution, or InAuth-specific public code repository for the product line.
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.
InAuth (American Express) is tracked in the API Evangelist network. This page is the human-readable profile that sits on top of the machine-readable index we maintain at apis.io.
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 — InAuth (American Express) scores 9.2/100 (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.
