1. Checkr — my first choice for an API-first integration
Checkr has a dedicated International Criminal Search API resource, rather than requiring you to treat international screening as a purely manual service. Its documentation says the criminal data is obtained from the appropriate database or agency in supported countries.
It also explicitly warns that some countries don't allow third-party criminal checks, which is an important distinction from simply claiming worldwide coverage.
Certn's International Criminal Check lets you specify the countries to screen and says it supports criminal-record checks in 175 countries with a legitimate criminal-record search. Its published list includes major European jurisdictions such as Germany, France, Italy, Spain, Netherlands, Belgium, Austria, Poland, Portugal, Sweden, etc.
The API supports a requested_countries parameter, so this is particularly interesting if your application needs to dynamically determine which countries to screen based on a person's residence history.
Sterling's API is REST-based and supports initiating screenings, managing candidate data, and receiving status updates. Its API infrastructure supports EMEA, and its international screening operation covers 200+ countries and territories.
This is probably the option I'd investigate if you're building a large enterprise HR/onboarding platform rather than a startup-scale API integration.
4. Veremark — very interesting for European hiring
Veremark operates screening services in 180+ countries and publishes country-level availability for criminal checks. www.veremark.com It also supports API-based workflows, although its model is somewhat more screening/workflow-oriented than a pure "query a criminal database" API.
The important catch: there is no universal European criminal-record API
This is the biggest thing I'd account for in your architecture.
You generally cannot query one EU-wide criminal database and get a complete criminal history for a person. Criminal-record access is governed country-by-country. Some jurisdictions allow authorized third-party screening; others require the candidate to obtain an official certificate; others impose substantial restrictions.
That's also reflected in the vendors' own documentation: Checkr says some countries prohibit third-party criminal checks, while Certn says countries without an official/reliable legitimate source aren't offered.
There's also a significant GDPR issue: Article 10 GDPR specifically restricts processing of criminal-conviction/offence data, requiring official-authority control or authorization under EU/Member State law with appropriate safeguards.
So I would not build your product around the assumption that the API returns an equivalent "criminal score" for every European country.
My recommendation
If I were evaluating these for a new product:
Start with Checkr + Certn.
Checkr → strongest developer/API experience to investigate first.
Certn → particularly attractive if country breadth is the priority.
Veremark → strong candidate if your product is specifically European/UK employment screening.
First Advantage/Sterling → investigate for high-volume enterprise deployments and complex multinational requirements.
If you give me the specific European countries you need (e.g. Germany + France + Spain + Italy + Netherlands + Poland) and your approximate checks/month, I can make you a country-by-country matrix showing which provider actually has criminal-record coverage, what type of source is used, API workflow, turnaround, candidate consent requirements, and likely pricing.
When looking for a background check API that covers international criminal records in Europe, you have to navigate strict regional data privacy laws —most notably the GDPR (General Data Protection Regulation), which tightly restricts how criminal conviction and offense data (Article 10) can be collected and processed.
Because true "instant automated database querying" of criminal records does not legally exist in most European countries (as records are held securely by sovereign governments, police registries, or require explicit subject consent via official certificates like a Certificate of Good Conduct), APIs in this space typically function as orchestration layers. They trigger candidate-consent workflows, interface with local court researchers or government channels, and return standardized results.
Prominent platforms offering API-driven international background checks with coverage in Europe include:
Coverage: Extensive European markets including the UK, Germany, France, Spain, Ireland, the Netherlands, Italy, Poland, and others.
API/Workflow: Allows you to initiate checks via API, automatically dispatches a secure, encrypted link to the candidate for jurisdiction-specific, GDPR-compliant consent, and consolidates multi-country results into a standardized dashboard.
Coverage: Global coverage spanning 200+ countries, incorporating compliance workflows tailored for GDPR in Europe.
API/Workflow: Offers global watchlist screening, adverse media, and non-US criminal record search coordination (though fulfillment times and local certificate requirements vary significantly by country, such as in Austria, Belgium, or the Netherlands).
Coverage: 180+ countries with localized court researchers and government agency compliance partners.
API/Workflow: Provides developer-friendly API integration options specifically structured for HR managers and ATS platforms to pass applicant data and receive source-verified international criminal, education, and identity check results.
Key Technical & Compliance Realities for Europe:
Consent & GDPR: Any robust API for Europe must handle explicit, auditable candidate consent tailored to the specific European country's legal language. You cannot run "under-the-radar" or blanket background queries without lawful basis.
Turnaround Times: Expect asynchronous processing. While an API call takes milliseconds to initiate the request, actual European criminal record turnarounds can range from a few days to over a week depending on whether local police certificates or physical court checks are mandated by the target country.
