输入模式
{'type': 'object', 'required': ['operation', 'value1', 'value2'], 'properties': {'value1': {'type': 'number', 'description': "For 'of', the percentage itself (25 means 25%). For 'increase' and 'decrease', the base amount being adjusted. For 'change', the original value. Must be a finite number."}, 'value2': {'type': 'number', 'description': "For 'of', the amount the percentage is taken from. For 'increase' and 'decrease', the percentage to apply (10 means 10%). For 'change', the new value. Must be a finite number."}, 'operation': {'enum': ['of', 'increase', 'decrease', 'change'], 'type': 'string', 'description': "Which calculation to run. 'of' = value1 percent OF value2. 'increase' = value1 raised BY value2 percent. 'decrease' = value1 reduced BY value2 percent. 'change' = the percentage change going FROM value1 TO value2, which errors when value1 is 0. Required; any other value is rejected."}}}
输入模式
{'type': 'object', 'required': ['encoded'], 'properties': {'encoded': {'type': 'string', 'description': "Standard Base64 text. Surrounding whitespace and missing '=' padding are tolerated; the URL-safe alphabet (- and _) is not."}}}
输入模式
{'type': 'object', 'required': ['token'], 'properties': {'token': {'type': 'string', 'description': "The full JWT: three base64url segments separated by dots (header.payload.signature). Surrounding whitespace is trimmed; a 'Bearer ' prefix is not stripped and will fail. Anything without exactly three segments is rejected."}}}
输入模式
{'type': 'object', 'required': ['text'], 'properties': {'text': {'type': 'string', 'description': 'The plain text to encode, interpreted as UTF-8. Must be a string; raw binary cannot be passed through this parameter.'}}}
输入模式
{'type': 'object', 'required': ['json'], 'properties': {'json': {'type': 'string', 'description': 'The JSON document as a string. Must be strict JSON — comments and trailing commas are parse errors.'}, 'indent': {'type': 'number', 'description': 'Spaces per indent level in `formatted`, 0 to 10. Default 2; a value outside that range or a non-number silently falls back to 2. Use 0 for newlines with no indentation, or read `minified` for no whitespace at all.'}}}
