{'type': 'string'}
units_convert_temperature
Converts a temperature value (decimal string) between C, F, and K. Offset-aware, not a bare multiplier.
Eingabeschema
{'type': 'object', 'required': ['value', 'from', 'to'], 'properties': {'to': {'type': 'string', 'description': 'C, F, or K'}, 'from': {'type': 'string', 'description': 'C, F, or K'}, 'value': {'type': 'string', 'description': 'decimal string'}}, 'additionalProperties': False}
Ausgabeschema
{'type': 'string'}
url_validate
Checks value is a well-formed absolute URL (has both a scheme and a host) â syntax only, not a reachability check.
Eingabeschema
{'type': 'object', 'required': ['value'], 'properties': {'value': {'type': 'string', 'description': 'identifier or value to check'}}, 'additionalProperties': False}
Ausgabeschema
{'type': 'object', 'required': ['valid'], 'properties': {'valid': {'type': 'boolean'}, 'reason': {'type': 'string'}}, 'additionalProperties': False}
uuid_generate
Generates count (default 1, max 1000) random version-4 UUIDs from crypto/rand-backed entropy.
Eingabeschema
{'type': 'object', 'properties': {'count': {'type': 'integer', 'description': 'default 1, max 1000'}}, 'additionalProperties': False}
Ausgabeschema
{'type': 'object', 'required': ['values'], 'properties': {'values': {'type': ['null', 'array'], 'items': {'type': 'string'}}}, 'additionalProperties': False}
uuid_validate
Parses value as a UUID and reports its version/variant if well-formed.
Eingabeschema
{'type': 'object', 'required': ['value'], 'properties': {'value': {'type': 'string', 'description': 'digits-only identifier to validate (no spaces or dashes)'}}, 'additionalProperties': False}
Ausgabeschema
{'type': 'object', 'required': ['value', 'valid'], 'properties': {'valid': {'type': 'boolean'}, 'value': {'type': 'string'}, 'variant': {'type': 'string'}, 'version': {'type': 'integer'}}, 'additionalProperties': False}
vateu_validate
Format validation only (no VIES lookup) for an EU VAT number: checks the 2-letter member-state prefix (EL for Greece, XI for Northern Ireland) against that country's digit/letter pattern. A format-valid result does not mean the number is actually registered.
Eingabeschema
{'type': 'object', 'required': ['value'], 'properties': {'value': {'type': 'string', 'description': 'identifier or value to check'}}, 'additionalProperties': False}
Ausgabeschema
