National Bank of Canada

National Bank of Canada (Banque Nationale du Canada, TSX: NA) is a Schedule I chartered bank headquartered in Montreal, Quebec, founded in 1859. It is the sixth-largest of Canada's Big Six banks and the leading bank in Quebec, serving personal, commercial, wealth-management, and financial-markets clients. On open finance, National Bank is a notable first-mover: it was the first major Canadian bank to launch a secure, consent-based data-sharing API for retail customers, but it does NOT operate a public self-serve first-party developer portal. Programmatic access to customer financial data is delivered through aggregators rather than a downloadable public API — principally Flinks, the Montreal aggregator in which National Bank holds an ~80% stake, via its Open Banking Environment (OBE), and also through Plaid. National Bank and Flinks are founding participants of the FDX Canada working group, aligning their data-sharing on the FDX technical standard, and the bank is positioning ahead of Canada's forthcoming, legislated-but-not-yet-operational Consumer-Driven Banking framework (Budget 2024 / FCAC oversight). Today access is voluntary and aggregator-mediated; there is no operational open-banking mandate and no public first-party API surface.

National Bank of Canada is listed with 1 API on the APIs.io network. Tagged areas include Financial Services, Banking, Canada, Big Six, and Open Banking.

Regulatory Posture applies to this provider. Its tags matched the Banking & Open Finance regime, so Regulatory Posture carries 15 points of the composite. If this regime is wrong for your business, say so on your provider repo — the applicability map is public and we will correct it.

Create-or-Update Ergonomics could not be measured. We hold no machine-readable contract for this provider to read, so there is nothing to measure a write surface against. Excluded rather than scored zero: never-measured and measured-empty are different facts. Publishing an OpenAPI is what makes this facet — and several others — scorable at all.

The six quality facets above are damped to 85 points between them, because the conditional facet above carries the other 15. That is why each facet's contribution is shown against a damped maximum: raising a quality facet moves the composite by 85% of its nominal weight, not 100%. The full arithmetic is at apis.io/rating/.

Agent readiness — checks not met, largest first (exact, from this profile):

Machine-Readable Contract +18 pts — api_specs includes an OpenAPI document
MCP Server +12 pts — deployment.mode + probe verdict on the mcp/ manifest, not the pointer; an unprobed slug falls back to authorship
Agentic Access Contract +10 pts — agentic_access artifact present (x-agentic-access), graded by author
Machine-Readable Auth +10 pts — a served openid-configuration/oauth-authorization-server carrying `issuer` (served), else the securitySchemes class in the provider OpenAPIs — bound (mutualTLS, DPoP, Signature) > negotiable (oauth2 authorizationCode/clientCredentials, openIdConnect) > bearer (http bearer, apiKey)
Idempotency +9 pts — OpenAPI mutating operations declare an idempotency key — a header, a request-body property, or a named de-duplication token whose own description says so (verified); else common[].type matches /idempoten/i (documented)
Stable Error Semantics +8 pts — OpenAPI $refs a shared error schema across 4xx/5xx responses (verified), else common[].type includes ErrorCatalog / ErrorCodes / DeclineCodes

Markets this provider is in provisional

The Kin Score Market layer reads a provider inside its market: its position, and how deep its integrations go. Depth is only comparable within a position. Provisional and unweighted: not part of the Kin Score or agent readiness.

Market	Position	Depth	Registered MCP server	Declares compatibility
Consumer Lending Licensing (UK, US, Canada credit licence registers)	regulated	38.3 (thin)	-	-
Canada RPAA Payment Service Providers (Bank of Canada registry + Payments Canada)	regulated	38.3 (thin)	-	-

Registered MCP server and declares compatibility are report only — not weighted. Undeclared means we found nothing we can read, so there is no number: we never infer integrations.

Standards this provider implements or carries. De facto ones are profiled and measured by the API Commons; formal ones come from the standards directory and are linked by the provider's own tags. The evidence column says how each claim was established — not that it was made.
