Irish CRO number

Endpoint GET /v1/ie/cro

What it covers

Returns an Irish CRO (Companies Registration Office) number: a plain six-digit number with no checksum. Set `edge=true` for boundary values of the six-digit range.

Parameters

ParameterTypeDescription
countinteger1–1000Number of records to return, 1–1000 (your plan may lower this). Omitted returns a single record; set it for a batch.
edgebooleanRestrict output to valid edge-case CRO numbers from the rare corners.
extremebooleanReturn 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.
invalidbooleanReturn a deliberately invalid value that fails validation, for testing rejection paths.
seedintegerInteger seed for reproducible output: the same seed always yields the same record.

Response fields
