Mark43

Mark43 is a cloud-native public safety software company whose platform unifies computer-aided dispatch (CAD), records management (RMS), first-responder mobile applications, evidence and property management, and analytics for law enforcement and public safety agencies. Serving more than 300 federal, state, and local agencies, Mark43 exposes a Partnerships (External) API that lets approved location providers, community-engagement software, and other law-enforcement technologies integrate directly with an agency's Mark43 tenant. The REST API provides endpoints for reports, persons, evidence and chain-of-custody, attachments, CAD events and configuration, warrants, tasks, users, vehicles, and E911 data, secured with HTTP Basic authentication using agency-issued API tokens and returning a consistent JSON response envelope.

Mark43 publishes 15 APIs on the APIs.io network, including Associated Records API, Attachments API, CAD Configuration API, and 12 more. Tagged areas include Company, Public Safety, Law Enforcement, Records Management, and Computer-Aided Dispatch.

Mark43’s developer surface includes documentation, API reference, authentication, and 14 more developer resources.

Regulatory Posture applies to this provider. Its tags matched the Government & Public Sector 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.

The six quality facets above are damped to 85 points between them, because the conditional facet above carries the other 15. That is why each facet's contribution is shown against a damped maximum: raising a quality facet moves the composite by 85% 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/. This rating is computed from github.com/api-evangelist/mark43: open an issue to ask a question, or submit a pull request to add artifacts. Want it done for you? Prioritized profiling — $2,500 →
