H&R Block

H&R Block (NYSE: HRB) is a US tax-preparation company and Fortune 1000 constituent, operating retail tax offices, consumer and small-business tax software, and the MyBlock digital platform. It runs no public developer program: the hosts that make up its API estate — api.hrblock.com, developer.hrblock.com, the apiportal.hrblock.com Apigee portal, apigw, mcp, edge, services and connect — either do not resolve or refuse connections from the public internet, and integration is arranged bilaterally through the tax-import partner program. The one machine-readable contract H&R Block does serve publicly is the OAuth 2.0 / OpenID Connect discovery metadata for its customer identity platform at login.hrblock.com.

H&R Block publishes 2 APIs on the APIs.io network. Tagged areas include Tax Preparation, Financial-Services, Fortune 1000, Identity, and Authentication.

H&R Block’s developer surface includes support, engineering blog, authentication, and 16 more developer resources.

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.

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 github.com/api-evangelist/hanr-block: open an issue to ask a question, or submit a pull request to add artifacts.
