Search sex offender records

Search the national sex offender registry by name, address, zip code, GPS coordinates, or free-text query. For quick demos, GET with the key query parameter remains supported. For production, prefer POST with X-API-Key or Authorization: Bearer and JSON body fields. Send optional X-Request-Id for customer-side request correlation.

get/sexoffender

Query parameters

keystring

Your API key (required). If using POST, you can send it in X-API-Key or Authorization: Bearer instead.

firstNamestring

First name of offender

lastNamestring

Last name of offender

dobstring date

Date of birth (YYYY-MM-DD). Regular Search matches exact records by full date, year_month records by year and month, and year records by year. Records with no stored DOB are excluded. A record with unknown precision but a stored date must match the full date. Extensive Mode may also return possible matches with a partial or missing DOB.

citystring

Residence city

statestring

Residence state (full name or 2-letter code)

zipcodestring

Residence zip code

addressstring

Street address search. Fuzzy by default; supports common address abbreviations and is billed at the fuzzy search rate (+$0.02/call). Do not combine with q or lat/lng. If combined with mode=extensive, also send firstName and lastName so enriched name results can be filtered by address.

latnumber

Latitude for GIS radius search

lngnumber

Longitude for GIS radius search

radiusnumber

Radius in miles for GIS search (default 1, max 100)

mode'extensive'

Set to 'extensive' to check additional live sources and return aliases, locations, and stateData where available. Results with a partial or missing DOB may still appear, so the result count can differ from Regular Search. +$0.05/call.

fuzzyboolean

Enable typo-tolerant fuzzy name matching for structured name fields. Handles spelling variations, partial first names, nicknames, aliases, and hyphenated surnames. Structured address searches are fuzzy by default and do not require this flag. +$0.02/call.

qstring

Free-text search across names, aliases, address, city, and zip code. Use with fuzzy=true instead of firstName/lastName.

prefixMatch'firstName' | 'lastName'

Enable prefix matching on the specified name field

uuidstring

Pull a single record by UUID

personUuidstring

Pull a single record by Person UUID

faceIdstring

Face ID from Facial Search API

createdAtStartstring date

Filter by first appearance in system (YYYY-MM-DD)

createdAtEndstring date

Filter by first appearance in system (YYYY-MM-DD)

updatedAtStartstring date

Filter by last update in system (YYYY-MM-DD)

updatedAtEndstring date

Filter by last update in system (YYYY-MM-DD)

pageinteger

Page number for GIS search pagination. Each page is billed as a separate API call.

Headers

X-Request-Idstring

Optional opaque client correlation ID. Use a UUID or similar request ID; do not include names, emails, DOBs, member IDs, patient IDs, search values, or other sensitive data.
