Checkr

Checkr is a technology-driven background check platform for employment screening. Its REST API lets employers, staffing firms, and platform partners run compliant background checks programmatically - creating candidates, sending invitations, ordering packages, and retrieving reports composed of individual screenings (SSN trace, county/state/national/federal criminal searches, sex offender registry, motor vehicle records, education and employment verifications, and more). The API also covers adverse action workflows, continuous checks and subscriptions, node/hierarchy and geo account structure, Form I-9, documents, and webhooks for event-driven report status updates. Authentication is HTTP Basic auth with a secret API key, with OAuth for Checkr Partner integrations.

Checkr publishes 14 APIs on the APIs.io network, including Account API, Adverse Actions API, Candidates API, and 11 more. Tagged areas include Background Checks, Employment Screening, Compliance, HR Tech, and Identity Verification.

Checkr’s developer surface includes authentication, documentation, and 9 more developer resources.

Where this information came from

This is an independent, third-party profile of Checkr, published by API Evangelist. We do not operate, host, resell, or support these APIs, and we are not affiliated with or endorsed by the company unless stated above. Everything here is built from publicly available information — the company's own site, developer portal, documentation, public repositories, and the specifications it publishes for public use. Nothing is obtained by breaching a system, defeating an access control, or using credentials.

The Kin Score and Agent Readiness rating are independently calculated assessments of a company's public API artifacts, scored against a published rubric. They are not certifications, endorsements, security assessments, or audits.

Corrections, re-scores, and removal are free — no partnership or purchase required, and you do not need to justify the request. A removed company is recorded as unrated, never scored zero for having asked. Acknowledgement within one business day; removal within two.
