Czech email address

Endpoint GET /v1/cz/email

What it covers

Returns a realistic synthetic Czech email address: a name-based local part (romanised to ASCII) on a free webmail, a Czech regional provider, or a corporate domain built from a Czech company brand. `domain` pins an exact domain; `domainCategory` (`free`/`regional`/`corporate`/`any`) scopes a weighted-random draw. `pattern` selects the local-part shape or `any`. `plusTag` controls plus-addressing; `exotic=true` allows the rarer RFC-valid characters.

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.
domainstringpattern ^[A-Za-z0-9.-]+\.[A-Za-z]{2,}$Pin an exact domain, e.g. "gmail.com". Overrides domainCategory.
domainCategory"free" | "regional" | "corporate" | "any"Scope the random domain draw: free webmail, regional providers, corporate domains, or any.
edgebooleanRestrict output to edge-case addresses from the rare corners of the format.
exoticbooleanAllow rarer RFC-valid local-part characters (%, =, ~). Off by default.
extremebooleanReturn a correct address whose value is wrapped in a hostile encoding (untrimmed whitespace, invisible/zero-width characters, BOM, homoglyph letters, or bidi/combining marks). localPart, domain, and the decomposition stay clean.
invalidbooleanReturn a deliberately invalid value that fails validation, for testing rejection paths.
pattern"first.last" | "firstlast" | "first_last" | "first.last.number" | "flast" | "initial.last" | "noun.number" | "first.company" | "company.first" | "any"Local-part shape, e.g. "first.last"; "any" picks a weighted-random one.
plusTagstringpattern ^[A-Za-z0-9_-]+$Plus-addressing tag: "true" adds a random tag, "false" none, any other value is used verbatim.
seedintegerInteger seed for reproducible output: the same seed always yields the same record.
