}'Scored, de-duplicated, source-tagged records
Not a wall of raw registry rows — a ranked answer your team can act on and defend.
Same drop-in integration, materially better data
A contract designed for background screening — not an aggregator copy.
Per-source provenance
Every match says which registry it came from, when we last saw it, and links back to the official state record. Prove “this came from the NJ registry.”
Scored matches
matchConfidence and matchBasis on every record cut manual adjudication of common-name false positives. offenders.io returns none.
Freshness as a priced field
lastCheckedAt on every record. A background store re-verifies on a schedule. Choose Standard, Weekly, or Daily per call.
Verification report
A branded, timestamped PDF/HTML report of your search results that cites the originating registry and links back to the official record — a defensible audit artifact. It is your report of public-record data, clearly labeled as Offendersearch output; it does not reproduce, mirror, or impersonate any government website. Billed per document, on every account.
Fastest, freshest database
The most frequently refreshed offender database in the category — typical calls return in milliseconds, with async available for the deepest sweeps.

Frequently asked questions
How is Offendersearch different from offenders.io?
Every match carries a confidence score, the basis for the match, and per-source provenance with a link back to the official registry record. Freshness is a first-class, priced field.
Which registries do you cover?
Nationwide — all 50 states, DC, and US territories, drawn from official state and national sources and normalized into one schema and one API call.
How fast is a search?
A cache-first materialized store means a typical call is a read, not a live crawl. State-scoped queries touch one source and return in well under a second; deep national sweeps can run async.
Is this a consumer report?
No. Offendersearch is not a consumer reporting agency and results are not a consumer report. Do not use them for FCRA-covered decisions without appropriate process.
