Steps
Use the official Search NSOPW tool at nsopw.gov to query by name or by state/location across all 50 states, DC, U.S. territories, and Indian Country
Understand that NSOPW works by federating real-time web-service calls out to each state/tribal jurisdiction's own registry at search time, rather than hosting a unified database itself
Do not assume a public REST/JSON API exists for this site — DOJ has not published one; treat this as a browser-facing tool only
For jurisdiction-specific detail or bulk needs, use the Registries directory (nsopw.gov/all-registries) to go directly to the state registry in question, since individual states vary in what (if any) bulk or API access they offer
Route any need for automated/bulk lookups through your compliance/legal team, since scraping a federated criminal-justice registry has legal and accuracy implications beyond typical API integration work
Known gotchas
Because NSOPW re-queries state systems live, result completeness and format depend on the target state's own system being up — a 'no results' response doesn't necessarily mean no record exists nationally
Third-party vendors advertise 'NSOPW APIs,' but these are unofficial scrapers/resellers, not something DOJ operates or endorses — their accuracy and terms-of-service compliance is your own diligence, not NSOPW's
