Arkose Labs

aid: arkose-labs
name: Arkose Labs
description: 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.

- name: Arkose Labs Verify API
  description: Server-side API for validating an Arkose Labs session. The customer server POSTs the Arkose private key and
    the client-side session token and receives whether the session was solved plus a full risk assessment (risk band / score,
    telltales, IP / device / email intelligence, agent trust). Always called server-side; do not fail-open on HTTP 400.

- name: Arkose Labs Edge API
  description: Lightweight server-side detection API. The customer relays the inbound client HTTP request (method, url, headers,
    body) to Arkose Edge, which returns a risk assessment and allow/deny recommendation from consortium intelligence — for
    surfaces where client-side JavaScript / SDK cannot run (mobile backends, IoT, programmatic APIs).
