Silver Tail
Silver Tail Systems was a website fraud and abuse detection company founded in 2008 in Menlo Park, California by Mike Eynon and Laura Mather, both formerly on the anti-fraud team at eBay/PayPal. Its product collected and analyzed real-time web traffic to deliver web session intelligence and predictive analytics that detected fraud, account takeover, and abuse on banking and commerce websites. Backed by Andreessen Horowitz (a16z) among others, the company raised roughly $20M across three rounds before being acquired by RSA, the security division of EMC, in 2012 and rebranded as RSA Web Threat Detection. It no longer exists as an independent company and publishes no live developer or API surface.
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.
Silver Tail 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 — Silver Tail 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.

Silver Tail is in the network as a tracked entity. We haven't yet indexed a public API surface for it — when one is published, the artifacts, score, and agent-readiness read will appear here automatically. The source repository is where that profile is built.
