Dutch person
Endpoint GET /v1/nl/person
What it covers
Returns a synthetic Dutch person: given name(s), surname, initials, birth date, and a matching BSN. The Dutch BSN is non-semantic (it encodes neither sex nor birth date), so the birth date is drawn independently within any age/birth-date filters (contradictory combinations are rejected with a 400) and `sex` forces the gendered form of the name. Set `invalid=true` for a person whose BSN has a deliberately wrong elfproef check digit. `edge=true` biases the BSN and name shape toward their rare corners. Set `caseStrict=false` to deliberately mangle the name/surname casing.
Parameters
| Parameter | Type | Description |
|---|---|---|
| atAge | integer | Exact age in years at request time. |
| bornAfter | stringpattern ^\d{4}(?:-\d{2}(?:-\d{2})?)?$ | Born after this date or fragment (YYYY, YYYY-MM, YYYY-MM-DD). |
| bornBefore | stringpattern ^\d{4}(?:-\d{2}(?:-\d{2})?)?$ | Born before this date or fragment (YYYY, YYYY-MM, YYYY-MM-DD). |
| bornOn | stringpattern ^\d{4}(?:-\d{2}(?:-\d{2})?)?$ | Born on a date or within a fragment: YYYY, YYYY-MM, or YYYY-MM-DD. |
| caseStrict | boolean | Defaults to true (proper casing). Set false to deliberately mangle the casing of name and surname (all-lower, all-upper, or random); initials stay proper uppercase. |
| count | integer1–1000 | Number of records to return, 1–1000 (your plan may lower this). Omitted returns a single record; set it for a batch. |
| edge | boolean | Restrict the BSN to edge-case values and bias the name shape. |
| extreme | boolean | Return a correct person whose name and surname are wrapped in a hostile encoding (untrimmed whitespace, invisible/zero-width characters, BOM, homoglyph letters, or bidi/combining marks). initials, birthDate, and the national identifier stay clean. |
| invalid | boolean | Return a person whose BSN has a deliberately wrong elfproef check digit. |
| olderThan | integer | Minimum age in years at request time. |
| seed | integer | Integer seed for reproducible output: the same seed always yields the same record. |
| sex | "m" | "f" | Encoded sex: "m" or "f". |
| youngerThan | integer | Maximum age in years at request time. |
