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.

InAuth (American Express) is profiled on the APIs.io network. Tagged areas include Company, AI Infrastructure, Fraud Prevention, Device Intelligence, and Authentication.

Create-or-Update Ergonomics could not be measured. We hold no machine-readable contract for this provider to read, so there is nothing to measure a write surface against. Excluded rather than scored zero: never-measured and measured-empty are different facts. Publishing an OpenAPI is what makes this facet — and several others — scorable at all.
Improve this rating by publishing the missing artifacts — every area above can be raised, and the full rubric is at apis.io/rating/. Every facet and dimension name above is a link: it opens that measurement's own page — what it means, the exact checks that feed it, how the whole catalog distributes on it, and the providers at the top of it. This rating is computed from github.com/api-evangelist/inauth-american-express: open an issue to ask a question, or submit a pull request to add artifacts.
