Arkose Labs

Arkose Labs is a bot management and account-security platform (the Arkose Bot Manager / Titan platform) that protects login, registration, and other high-value user flows from bots, fraud, and abuse. It combines a client-side detection engine and adaptive Enforcement Challenge with a server-side Verify API that returns a risk assessment (risk band, score, telltales, IP / device / email intelligence, and agent trust) for every session, plus a lightweight server-side Edge API for surfaces where client JavaScript cannot run. The developer surface includes the Verify API v4, Edge API, Truth Data and Retroactive Attack Insights APIs, mobile SDKs (Android, iOS, React Native), CDN integrations (Akamai, Cloudflare, Fastly), and a public status page.

Arkose Labs publishes 3 APIs on the APIs.io network: Edge API, Schema API, and Verify API. Tagged areas include Company, Enterprise, Security, Bot Management, and Fraud Prevention.

Arkose Labs’ developer surface includes documentation, API reference, getting-started guide, engineering blog, support, authentication, and 18 more developer resources.
