Certn

Certn is a Canada-based, globally operating background check and identity verification platform. Its RESTful API lets HR, property management, gig, and marketplace platforms order and retrieve criminal record checks, identity verification, credit, employment, education, credential, and reference checks across 200+ countries, then receive results and adjudicated reports. The API authenticates with OAuth 2.0 client credentials (Client ID / Client Secret exchanged for a Bearer token) and pushes status updates via signed webhooks. The original api.certn.co v1 REST API is deprecated (discontinued 2026-08-05) in favor of the newer CertnCentric APIs; both are modeled here honestly.

Certn publishes 6 API contracts indexed on the APIs.io network, including Applications API, Checks API, Packages API, and 3 more. Tagged areas include Background Checks, Identity Verification, Criminal Record Check, Screening, and Human Resources.

Certn’s developer surface includes authentication, documentation, engineering blog, and 11 more developer resources.

Regulatory Posture applies to this provider. Its tags matched the Employment & Payroll regime (on an ambiguous tag, where no other regime matched), 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.

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
RegTech, AML/KYC and Money Transmission	undeclared	-	-	-
Biometrics Testing (biometric recognition vendors, identity verification depth)	undeclared	-	-	-

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.
