description: 'Fnality International is a London-headquartered financial market infrastructure
  company that builds and operates distributed-ledger wholesale payment systems settling
  in tokenised central bank money. Backed by a consortium of 24 global financial institutions
  — including Banco Santander, BNY, Barclays, BNP Paribas, Citi, Goldman Sachs, State
  Street and UBS — Fnality launched the Sterling Fnality Payment System (£FnPS) in
  2024 as the first regulated DLT-based payment system supervised by the Bank of England,
  with US Dollar and Euro payment systems in development. The systems run on private
  Ethereum networks, giving participant banks 24/7 availability, real-time atomic and
  PvP settlement, programmable money and T+0 cross-border liquidity movement. Fnality
  Services is the operational and product-delivery arm that licenses software to participants
  and runs inter-system arrangements. Technical documentation for participants is hosted
  in a credential-gated Archbee space at docs.fnality.com; Fnality publishes no public
  developer portal, API reference or machine-readable specification.'

  detail: >-
    Fnality's only technical documentation lives in an Archbee space at
    docs.fnality.com that answers HTTP 200 with a "Get a magic link to access
    space with your account — this is a password or guest account protected
    space" login shell instead of content, and every other candidate API host
    (api., developer., portal.fnality.com) returns NXDOMAIN, so the participant
    integration contract is reachable only by admitted institutions.
