BMO Financial Group
BMO Financial Group (Bank of Montreal) is one of Canada's Big Six banks and a Schedule I domestic chartered bank, founded in Montreal in 1817 as Canada's oldest bank. It is a diversified North American financial-services provider serving personal, commercial, wealth, and capital-markets clients across Canada and the United States (where it operates as the separately chartered BMO Bank N.A.). BMO runs a first-party, bilingual (EN/FR) commercial developer portal at developer.bmo.com for Online Banking for Business customers, publishing OAuth 2.0-secured Account Information, Account Validation, Image Retrieval, Payment (domestic and international / embedded finance), Authorize, and Encryption APIs on an IBM API Connect platform with a free sandbox and pre-production environment. Documentation and OpenAPI/API Explorer specs sit behind an approved organization account, so the surface is partner-gated rather than openly downloadable. Canada has no operational open-banking mandate yet — the federal Consumer-Driven Banking framework (Budget 2024 / Fall Economic Statement 2024, overseen by the FCAC) is legislated but not live — so consumer data access today remains voluntary and largely aggregator-based (Flinks, Plaid), while BMO's own public program is a commercial treasury/ payments API offering.
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 BMO Financial Group the way a machine reads it — 9 machine-readable artifacts across 6 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 — BMO Financial Group scores 31.0/100 (thin), with a separate agent-readiness read of 11/100 (agent aware). 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. Every facet and dimension name is a link: it opens that measurement's page on APIs.io, where the rating runs across the whole catalog — the exact checks that feed it, how every profiled provider distributes on it, and who is at the top of it.

How we profile BMO Financial Group
Each block below is one kind of artifact we hold for BMO Financial 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.
APIs 6
Each API is captured as its own OpenAPI definition — every operation, parameter, and response. This is the single most useful machine-readable description of what an API does, and it's what lets us score, lint, mock, and generate against it without asking the provider for anything.
Individual APIs this provider publishes, each with its own machine-readable definition.

BMO Encryption API

Security Posture 3
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.

This is an independent, third-party profile of BMO Financial Group, published by API Evangelist. We do not operate, host, resell, or support these APIs, and we are not affiliated with or endorsed by the company unless stated above. Everything here is built from publicly available information — the company's own site, developer portal, documentation, public repositories, and the specifications it publishes for public use. Nothing is obtained by breaching a system, defeating an access control, or using credentials.
The Kin Score and Agent Readiness rating are independently calculated assessments of a company's public API artifacts, scored against a published rubric. They are not certifications, endorsements, security assessments, or audits.
Corrections, re-scores, and removal are free — no partnership or purchase required, and you do not need to justify the request. A removed company is recorded as unrated, never scored zero for having asked. Acknowledgement within one business day; removal within two.
