The State of US Banking APIs

About this paper

I have now scored the two great mandated open-banking regimes — the UK’s OBIE and Australia’s Consumer Data Right — and in both the headline was a ceiling: a regulator forced an entire sector across the same line, and the whole field bunched up in “Developing,” because a mandate produces existence, not quality. The United States is the opposite experiment, and it produces the opposite shape. There is no mandate here — only the emerging, and currently contested, CFPB Section 1033 rule and the voluntary FDX standard — and the result is the widest distribution in my entire catalog: the only banking sector I have scored that reaches “Exemplar,” and the only one with a long “Minimal” tail. The top and the bottom are both real.

I read every one of the hundred and thirteen institutions the way an integrator or an agent would — not the marketing site, the machine-readable evidence — for two readers: the person who runs one of these programs and needs to know where they stand, and the investor trying to tell a real platform from a compliance filing. The single most important finding: in the absence of a mandate, an open-banking sector doesn’t average out, it splits in two. The six highest scores are not banks — they are the aggregators and banking-as-a-service platforms the banks quietly depend on. Of forty large chartered banks, two publish downloadable specs. Every credit union but one is an API dark zone. The infrastructure owns the rails; the banks rent them — and this report is the map of who holds what, scored provider by provider, with the investable thesis and a punch-list any institution could execute to move.

What's inside

1. Executive summary — no mandate, and the widest split in banking
2. The state of the sector — the opposite of a mandate
3. The resource taxonomy — three surfaces, and who actually ships them
4. The composite Kin Score — and why it's the foundation
5. Agent-readiness — potential everywhere, shipped almost nowhere
6. The blueprint — what the leaders satisfied, and what the field hasn't
7. Standards and artifacts — why this matters for the agentic turn
8. Security, auth, scopes, and consent — a floor of hygiene, a ceiling of a few
9. Provider-by-provider intelligence — leaders, incumbents, and the tail
10. The investable thesis — the rails, the reg, and the dark zone
