Axos Bank

Axos Bank is a branchless, digital-first federal savings bank chartered and regulated by the U.S. Office of the Comptroller of the Currency (OCC) and a member of the FDIC. Founded in 2000 as Bank of Internet USA and rebranded Axos in 2018, it is the primary banking subsidiary of Axos Financial, Inc. (NYSE AX), a Delaware financial holding company headquartered in San Diego, California with roughly $29 billion in consolidated assets. Axos offers consumer and commercial deposit, lending, and treasury-management products online, and runs a first-party developer / Banking-as-a-Service program. That program is real but partner-gated - the public API Store documents four API product families (Account Enrollment, Account Maintenance, Payment Solutions, and Account Reporting) secured with OAuth 2.0, but access requires contacting the Axos API team; there is no self-serve signup, no publicly downloadable OpenAPI/Swagger specification, and no documented first-party FDX participation or published CFPB Section 1033 data-access posture.

Axos Bank is listed with 4 APIs on the APIs.io network. Tagged areas include Financial Services, Banking, United States, Banking as a Service, and Open Finance.

Axos Bank’s developer surface includes engineering blog, authentication, documentation, support, and 9 more developer resources.

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
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
A2A Agent Card +8 pts — a2a/-a2a.yml manifest, graded on conformance.grade against A2A 1.0.0

12 more unmet checks in the Agent Readiness table above.

Kin Score — facets with the most composite points still available (weight × headroom):

Contract Quality scores 0.0 — up to +25.0 composite points
Access Clarity scores 27.6 — up to +14.5 composite points
Operational Transparency scores 0.0 — up to +13.0 composite points

Each check links to what satisfies it. Publish the artifact, or tell us where it already lives, and the score moves on the next scoring run.

Improve this rating by publishing the missing artifacts — every area above can be raised, and the full rubric is at apis.io/rating/. Every facet and dimension name above is a link: it opens that measurement's own page — what it means, the exact checks that feed it, how the whole catalog distributes on it, and the providers at the top of it. This rating is computed from the provider profile at artifacts.apis.io/axos-bank/apis.yml: open an issue on github.com/api-evangelist/axos-bank to ask a question or point us at an artifact you publish.

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	55.6	-	-
US Banks and Credit Unions (FDIC BankFind + NCUA insured credit unions)	regulated	55.6	-	-

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.
