  At-Bay is an InsurSec company that combines cyber insurance with proactive
  security monitoring for businesses. Headquartered in New York with offices in
  San Francisco and Tel Aviv, At-Bay underwrites Surplus Cyber, Surplus Tech
  E&O, and Surplus Miscellaneous Professional Liability (MPL) coverage and
  bundles them with the At-Bay Stance security platform (advisory, fraud
  defense, incident response) and 24/7 Managed Detection and Response (MDR)
  across endpoint, email (MXDR), and multi-vector surfaces. At-Bay distributes
  through a network of independent brokers and partners and exposes a
  production-grade REST Partner API (v2) that lets brokerage platforms,
  digital distributors, and agency management systems quote, customize, bind,
  renew, retrieve documents, and receive webhook callbacks for the full
  policy lifecycle. Demo environment at api-demo.at-bay.com lets partners
  integrate without going through Broker of Record clearance.

      End-to-end Partner REST API (v2) for the At-Bay quote-to-bind-to-renew
      workflow. Supports three insurance products selected via the
      `insurance_product` field on the policy object: CYB (Surplus Cyber),
      TEO (Surplus Tech E&O), and MPL (Surplus MPL). Core operations: POST
      /quotes to submit a new quote, GET /quotes/{quote_identifier} polled
      every 10 seconds until status leaves `quote_pending` (typical p90
      under 40 seconds), bind/referral/update operations, document upload
      and download, auto-renewal pause, plus webhook registration and
      verification for asynchronous status callbacks. JWT bearer
      authentication; production at api.at-bay.com/v2 and demo at
      api-demo.at-bay.com/v2. Production submissions are subject to
      Broker-of-Record (BOR) clearance — duplicate domains/addresses within
      60 days are blocked; the demo environment bypasses BOR.
