# Fnality International

> 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 24 global financial institutions, Fnality launched the Sterling Fnality Payment System (£FnPS) in 2024 — 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 and give participant banks 24/7 availability, real-time atomic and PvP settlement, programmable money, and T+0 cross-border liquidity movement.

**Fnality publishes no public API.** There is no developer portal, no API reference, no OpenAPI/AsyncAPI/GraphQL specification, no SDK in any package registry, no MCP server and no agent card. Technical documentation exists but sits in a credential-gated Archbee space at https://docs.fnality.com/, which returns a magic-link login rather than content. Integration is arranged bilaterally with admitted participant institutions through Fnality Services. This file is generated by API Evangelist from public pages only; it is not published by Fnality.
