The Vanguard Group

The Vanguard Group is an American investor-owned asset manager headquartered in Malvern, Pennsylvania, and is "the largest provider of mutual funds in the world" and the second-largest exchange-traded fund (ETF) provider after BlackRock's iShares. Vanguard manages approximately $12 trillion in assets as of 2025 and employs roughly 20,000 people (the "crew") as of December 31, 2024. The firm was founded on May 1, 1975 by John C. ("Jack") Bogle and is structured as a mutual: "Vanguard is owned by the funds managed by the company and is therefore owned by its customers." Salim Ramji was appointed Chief Executive Officer in July 2024. Vanguard's business spans index and active mutual funds, ETFs, personal advisor services, retirement plan recordkeeping (Vanguard Retirement Plan Services), institutional asset management, fixed income, and a financial-advisor channel served through Vanguard Financial Advisor Services. Vanguard operates across the Americas, Europe, and Asia Pacific. Despite that scale, Vanguard does not publish a public developer API program — there is no public OpenAPI specification, no SDKs, no CLI, no public webhooks, and no Vanguard-published public RSS feed. Investor, advisor, recordkeeping, and distribution-platform integrations are delivered through authentication-gated portals (investor.vanguard.com, advisors.vanguard.com, institutional.vanguard.com), PDF reporting, brokerage/custodian rails, fund-administrator data feeds, and industry recordkeeping interfaces.

human only

Index entry only — little beyond a description and a link, and nothing machine-readable enough for an agent to act on without a human reading the site first.

Kin Score

API Evangelist profiles The Vanguard Group the way a machine reads it — 7 machine-readable artifacts, 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 — The Vanguard Group scores 11.4/100 (minimal), with a separate agent-readiness read of 0/100 (human only). 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.

How we profile The Vanguard Group

Each block below is one kind of artifact we hold for The Vanguard Group. For each we say what it is and why it earns a place in the profile, then list every one we've indexed — capped at two rows, scroll within the panel for the rest.

GraphQL 1

Where a provider ships GraphQL, the schema is the contract. We profile it alongside the REST surface so the whole interface is legible in one place.
