BNY (Bank of New York Mellon)
BNY (rebranded from BNY Mellon in 2024, NYSE ticker changed from BK to BNY in May 2026) is the world's largest custodian bank, overseeing approximately $59.4 trillion in assets under custody and/or administration and $2.1 trillion in assets under management as of Q1 2026. BNY operates across Securities Services, Market & Wealth Services, and Investment & Wealth Management, with brand families including Pershing (clearing and custody for wealth managers, parent of NetX360+ and the Wove platform), Eagle Investment Systems (investment data management), Albridge (wealth data aggregation), BNY Markets (FX, securities finance, capital markets), and BNY Investments. BNY publishes APIs through the BNY Developer Marketplace at developer.bny.com (formerly marketplace.bnymellon.com), covering Asset Servicing, Treasury Services, Payments, Pershing, Markets, and the BNY Data On-Chain product, with registration and API reference gated behind a Nexen single sign-on.
Limited machine-readable signal and partial portal coverage — documentation a human can read, but little a machine or agent can consume without scraping.
API Evangelist profiles BNY (Bank of New York Mellon) the way a machine reads it — 15 machine-readable artifacts across 5 APIs, pulled from the provider's own public surface and indexed so a developer, an analyst, or an AI agent can evaluate it against every other provider on the network.
Every provider in the network is reduced to the same set of machine-readable artifacts — OpenAPI contracts, event specifications, GraphQL schemas, runnable collections, pricing and rate-limit signals, security posture, OAuth scopes, and the agent surfaces (MCP servers and skills) that let software drive the API on its own. We profile them because the interface is the part of a company you can actually inspect: it is a truer signal of what a provider does than any marketing page. From those artifacts we compute the Kin Score — BNY (Bank of New York Mellon) scores 36.4/100 (thin), with a separate agent-readiness read of 48/100 (agent ready). The full breakdown is below, followed by every artifact we hold — each card links through to its machine-readable definition on apis.io.
Kin Score
This is the API Evangelist rating — a single, repeatable read computed from the artifacts on this page. Green fill is points earned; the red track is points possible, so every bar shows earned-versus-possible at a glance.

OPEN COLLECTIONPricing Plans 1
Pricing is part of the interface. Machine-readable plans tell you what a tier costs and includes before you commit — one of the six things the Kin Score reads for commercial clarity.
Published pricing tiers and plan structures.
Rate Limits 1
Rate limits are the difference between a demo that works and a production integration that doesn't fall over. Publishing them is an operational-transparency signal — and a hard requirement for any agent that plans its own throughput.
Documented rate limits and quota policies.

RATE LIMITSFinOps 1
Cost, billing, and metering signals let a buyer model the financial operations of an API before it's live. We profile them for the same reason we profile pricing: the money is part of the contract.
Cost, billing, and metering signals for API financial operations.
Security Posture 2
Authentication, domain security, vulnerability disclosure, and trust-center signals — the evidence that a provider takes security seriously enough to document it. We profile it because you can't govern what you can't see.
Authentication, domain security, vulnerability disclosure, and trust-center signals.
Agentic Access 1
An x-agentic-access contract marks which operations are safe for an agent to run on its own and which need a human in the loop. It is the difference between an API an agent can use and one it can use safely.
Recommended x-agentic-access execution contracts for AI agents.
