Santander US
Santander Bank, N.A. (santanderbank.com) is the US retail and commercial banking subsidiary of Spain's Banco Santander S.A., headquartered in Boston, Massachusetts. It is a nationally chartered bank (National Association, regulated by the OCC) operating a branch network across the Northeast US (Massachusetts, New Hampshire, Rhode Island, Connecticut, New York, New Jersey, Pennsylvania and Delaware), which positions it as a super-regional bank. Unlike UK and Australian institutions bound by mandated open-banking contracts, and unlike US banks such as Capital One or Chase that publish first-party developer portals, Santander Bank N.A. exposes no public, first-party developer API for its US retail franchise: developer.santanderbank.com does not resolve, and the site publishes no developers/API/open-banking pages. Consumer-permissioned data access in the US is available today through aggregators rather than a direct API — Plaid supports "Santander - Personal" (Assets, Auth, Balance and Transactions). Santander's UK developer portal (developer.santander.co.uk) and the group's Corporate & Investment Banking API marketplace (apimarket.santandercib.com) are operated by separate legal entities and are not the US retail bank's surface. This record is an honest identity profile of a super-regional bank whose US open-finance posture is aggregator-mediated, with no documented first-party developer program.
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.
API Evangelist profiles Santander US the way a machine reads it — 1 machine-readable artifact, 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 — Santander US scores 14.6/100 (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.

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.
