validate_args

Validate arguments against the parameter JSON Schema. Uses jsonschema_rs (Rust-based) if available, falls back to jsonschema (pure Python), or skips validation if neither is installed.

Parameters

args

dict[str, Any]Required

Arguments to validate.

Returns

tuple[bool, list[str]] — A tuple of (is_valid, errors). When no validation library is available, returns (True, []).

Example

1 from signalwire import SWAIGFunction
2 from signalwire import FunctionResult
3 
4 func = SWAIGFunction(
5     name="lookup_account",
6     handler=lambda args, raw_data: FunctionResult("ok"),
7     description="Look up account status",
8     parameters={
9         "type": "object",
10         "properties": {
11             "account_id": {"type": "string", "description": "Account ID"}
12         },
13         "required": ["account_id"]
14     }
15 )
16 
17 # Valid arguments
18 is_valid, errors = func.validate_args({"account_id": "12345"})
19 print(f"Valid: {is_valid}, Errors: {errors}")
20 # Valid: True, Errors: []
21 
22 # Missing required argument
23 is_valid, errors = func.validate_args({})
24 print(f"Valid: {is_valid}, Errors: {errors}")
25 # Valid: False, Errors: ["'account_id' is a required property"]
