Green Check Verified

Green Check Verified (Green Check) is a New Haven, Connecticut specialty-banking compliance platform founded in 2017 that sits between financial institutions and the cannabis and other cash-intensive businesses they serve. Banks and credit unions use it to onboard cannabis-related businesses (CRBs), collect and review due-diligence documentation, validate that deposits trace to legally licensed sales, monitor licenses and negative news, and produce the BSA/AML oversight reporting examiners require. Its public developer product, Green Check Access, is a REST API suite that normalizes compliance, company and transactional data across more than twenty point-of-sale and seed-to-sale systems — Dutchie, Treez, Flowhub, Biotrack, Metrc, Cova, Canix, Greenbits and others — so service providers such as payroll companies, CRMs, lenders and fintechs can programmatically create and onboard CRBs and read their sales, products, inventory, customer and document data through one contract instead of one integration per POS.

Green Check Verified publishes 18 APIs on the APIs.io network, including Authentication API, CRB API, CRB Customers API, and 15 more. Tagged areas include Company, Cannabis, Compliance, Banking, and Financial-Services.

Green Check Verified’s developer surface includes authentication, documentation, API reference, getting-started guide, support, engineering blog, signup flow, and 23 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 applies to this provider. This API accepts writes, so it carries 10 points of the composite. It is scored from the published contracts themselves: whether a caller can create-or-update in one call, whether the write accepts a key the caller already holds, and whether the response says which branch ran. Without that, every write needs a search-and-branch in front of it, and the first time that check is skipped a duplicate record is created. Scored against the observed mean rather than raw — a provider at the catalog average is unchanged by this facet, not penalised by it.

The six quality facets above are damped to 75 points between them, because the conditional facet above carries the other 25. That is why each facet's contribution is shown against a damped maximum: raising a quality facet moves the composite by 75% of its nominal weight, not 100%. The full arithmetic is at apis.io/rating/.

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/green-check-verified: open an issue to ask a question, or submit a pull request to add artifacts.
