Slovenian vehicle registration plate
Endpoint GET /v1/si/vehicle-registration
What it covers
Returns a realistic Slovenian vehicle registration plate. `type` selects the kind: `standard` (default, region code + `LL-NNN`, e.g. LJ AB-123), `custom` (region-prefixed vanity group), `motorcycle` (region code + `LL-NN`), `military` (`SV NNNNN`), `diplomatic` (`CD NN-NNN`), `police` (`P NNNNN`), or `export` (region code + `ES-NNN`). Constrain a region-coded plate to a registration region with `region` (named by office seat, e.g. Ljubljana; an unknown name is a 400). The cosmetic `SLO` country marker is not part of the value and no plate carries a checksum. Use `format` to choose spaced or compact rendering.
Parameters
| Parameter | Type | Description |
|---|---|---|
| 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 output to edge-case plates from the rare corners of the format. |
| extreme | boolean | Return a correct value wrapped in a hostile encoding (untrimmed whitespace, invisible/zero-width characters, BOM, or bidi/combining marks). Homoglyphs are excluded so the value stays machine-parseable; it still validates after normalisation. |
| format | "with-space" | "compact" | Plate rendering: with a space or compact. Default with-space. |
| invalid | boolean | Return a deliberately invalid value that fails validation, for testing rejection paths. |
| region | string | Restrict a region-coded plate to a registration region by office seat (e.g. Ljubljana, Maribor, Koper). An unknown name is a 400; ignored for military/diplomatic/police. |
| seed | integer | Integer seed for reproducible output: the same seed always yields the same record. |
| type | "standard" | "custom" | "motorcycle" | "military" | "diplomatic" | "police" | "export" | Plate kind: standard, custom, motorcycle, military, diplomatic, police, or export. |
