BNY Mellon (legal parent The Bank of New York Mellon Corporation, rebranded to "BNY" in 2024) is a US money-center bank and the world's largest custodian, overseeing roughly $50 trillion in assets under custody and/or administration. Its principal banking subsidiary, The Bank of New York Mellon, is a nationally chartered bank (OCC-supervised) headquartered in New York City, operating across Securities Services, Market & Wealth Services, and Investment & Wealth Management with brand families including Pershing, Eagle Investment Systems, and BNY Markets. On open finance, BNY runs a genuine first-party developer program — the BNY Developer Marketplace at developer.bny.com (formerly marketplace.bnymellon.com) — publishing Treasury Services (payments, liquidity, cash management, trade finance, FX), Asset Servicing, Markets, and Pershing API families to corporate, fintech, and financial-institution clients. Registration and full API reference are gated behind Nexen single sign-on, and no OpenAPI/Swagger is publicly downloadable. BNY also ships a public, smart-contract-only "Data On-Chain" product that broadcasts fund accounting data to Ethereum. Consumer/business-banking account data is reached primarily through aggregators such as Plaid rather than a first-party consumer data API. No FDX participation or CFPB 1033 posture is publicly documented.
BNY Mellon publishes 5 APIs on the APIs.io network. Tagged areas include Financial Services, Banking, United States, Custody Bank, and Treasury Services.
BNY Mellon’s developer surface includes documentation, support, sandbox, and 9 more developer resources.
