Generate URL-safe NanoIDs with an optional size and custom alphabet.
Generate URL-safe NanoIDs with an optional size and custom alphabet.
| Argument | Type | Description |

}Generate monotonic ULIDs (26-character, lexicographically sortable by time).
| Argument | Type | Description |
|---|---|---|
| count | integer |

"type": "object",
"properties": {
"count": {
"type": "integer",
"default": 1,
"maximum": 1000,
"minimum": 1
}
}
}Generate one or more UUIDs. v7 (time-ordered) is best for database keys; v4 is fully random.
| Argument | Type | Description |
|---|---|---|
| count | integer | |
| version | string |
{
"type": "object",
"properties": {
"count": {
"type": "integer",
"default": 1,
"maximum": 1000,

},
"version": {
"enum": [
"v4",
"v7"
],
"type": "string",
"default": "v4"
}
}
}Deterministic name-based UUID v5 (SHA-1) for a name in a namespace (dns, url, oid, x500 or a UUID).
| Argument | Type | Description |
|---|---|---|
| name* | string | |
| namespace | string |
{
"type": "object",
"required": [
"name"
],
"properties": {
"name": {
"type": "string"
},
"namespace": {
"type": "string",
"default": "dns"
}
}
}Validate a UUID and report its version, variant and embedded timestamp (v1, v6, v7).
| Argument | Type | Description |

| uuid* | string |
{
"type": "object",
"required": [
"uuid"
],
"properties": {
