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.[](https://www.globalbackgroundscreening.com/post/international-background-check-compliance)
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: 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.[](https://www.globalbackgroundscreening.com/international-background-check)
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.
If you're building a product that needs to run international criminal record checks across European countries, I'd start with First Advantage or Sterling. Both offer background-screening APIs designed for integration into other platforms, with international screening capabilities.
One important distinction: there isn't a single unrestricted public API that lets you query every European country's official criminal records database. Commercial providers typically coordinate country-specific checks, subject to local access rules, consent requirements, and legal restrictions.
My top recommendations
1. First Advantage
(Best for enterprise scale)
Offers a global screening API, international criminal checks, and developer support. A strong starting point if you need broad geographic coverage and configurable screening workflows.
API and integration details:
2. Sterling
(Best documented API workflow)
Provides a REST API for creating screenings, retrieving results, and receiving status callbacks. Its documentation explicitly supports EMEA and global screening products, including country-specific criminal checks.
Developer docs:
3. Veremark
Offers the Verelink REST API for integrating background checks into your own application. Its workflow supports creating requests, receiving webhook status updates, and retrieving reports. It advertises screening services across more than 180 countries, with availability varying by check and country.
API:
4. Certn
Worth evaluating if you want a modern integration experience, API documentation, webhooks, and EMEA-focused infrastructure. However, verify the exact European criminal-check catalog: its documented international criminal-check workflow has specific market and product restrictions.

These are initial candidates, not a guarantee that every provider can run every type of check in every European country. Confirm coverage directly before choosing.
What to verify before committing
Country coverage: Ask for a country-by-country matrix covering the UK, Germany, France, Spain, Italy, the Netherlands, Poland, and any other target markets.
Type of check: Determine whether you need official national criminal certificates, employer-oriented criminal-record searches, or broader adverse-record screening. These are not interchangeable.
API access: Confirm developer credentials, sandbox access, webhooks, report formats, and whether checks can be ordered programmatically by country.
Candidate consent and privacy: Ask who collects consent, how identity is verified, where personal data is processed, and how GDPR and local employment-screening rules are handled.
Pricing and speed: Request per-country prices, minimum commitments, and typical turnaround times.
The EU's ECRIS system is the official mechanism for exchanging criminal-record information between national authorities, rather than a general-purpose commercial API available to any developer.
My recommendation
I'd shortlist First Advantage and Veremark first for a new platform, then compare Sterling's API against them if your priority is a mature enterprise screening integration.
One question that would help me narrow this down: What are you building the API for?
1. Use case
A SaaS platform or marketplace that needs to call the API
Employee hiring and HR screening
Contractor or gig-worker verification
Verifying official criminal-record certificates supplied by individuals
Prominent and compliant screening platforms providing developer-friendly APIs for international and European criminal record checks include:
Checkr International Background Checks : Offers global coverage spanning 200+ countries and territories. It supports localized compliance workflows (including GDPR considerations for Europe), candidate authorization gathering, global watchlist screening (Interpol, OFAC), and criminal history searches via unified API and ATS integrations.[]()
Verifile Open API : A UK-headquartered international screening provider featuring a RESTful JSON API. It allows you to build custom order management workflows, supporting candidate-driven or client-driven data entry and tracking for international compliance and criminal checks.[](https://www.verifile.co.uk/background-check-api)
If you share your primary use case (e.g., employment screening vs. tenant verification) and the specific European countries you need to target most, I can help narrow down which provider offers the best localized coverage and compliance model for your workflow.
