Texas Capital Bank
Texas Capital Bank, National Association is the banking subsidiary of Texas Capital Bancshares, Inc. (NASDAQ: TCBI), a Dallas-headquartered full-service financial services firm founded in 1998 with roughly $31.5 billion in assets (FYE 2025). As a nationally chartered commercial bank it serves businesses, entrepreneurs, and institutions across Texas and the United States with commercial and business banking, treasury management, mortgage/warehouse finance, and investment banking. On the open-finance dimension the bank is relationship-first rather than developer-first: it markets treasury and ERP API integrations (including its ConnectNow embedded banking for Sage and NetSuite, direct platform integrations, and SFTP/XChange file transfer) but exposes them through partner onboarding with dedicated bankers, not a public self-serve developer portal. There is no public first-party developer portal, no downloadable OpenAPI/Swagger, and no self-serve API signup. Consumer account and transaction data is made available to permissioned third parties through the Finicity (Mastercard) aggregator rather than a first-party API, which is the honest posture for most US regional banks under the voluntary, fragmented US open-banking landscape (CFPB Section 1033 and the industry FDX standard).
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 Texas Capital Bank the way a machine reads it — 3 machine-readable artifacts across 2 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 — Texas Capital Bank scores 8.6/100 (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.
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 Texas Capital Bank
Each block below is one kind of artifact we hold for Texas Capital Bank. 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 2
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.

This is an independent, third-party profile of Texas Capital Bank, 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.
