Path Parameters
Body
The base definition of a tool that can be used during a call. Exactly one implementation (http or client) should be set.
Additional parameters that are automatically set by the system when the tool is invoked.
The value to set for the parameter.
KNOWN_PARAM_UNSPECIFIED, KNOWN_PARAM_CALL_ID, KNOWN_PARAM_CONVERSATION_HISTORY, KNOWN_PARAM_OUTPUT_SAMPLE_RATE Where the parameter is used.
PARAMETER_LOCATION_UNSPECIFIED, PARAMETER_LOCATION_QUERY, PARAMETER_LOCATION_PATH, PARAMETER_LOCATION_HEADER, PARAMETER_LOCATION_BODY The name of the parameter.
Details for a client-implemented tool. Only body parameters are allowed for client tools.
The description of the tool.
The parameters that the tool accepts.
Where the parameter is used.
PARAMETER_LOCATION_UNSPECIFIED, PARAMETER_LOCATION_QUERY, PARAMETER_LOCATION_PATH, PARAMETER_LOCATION_HEADER, PARAMETER_LOCATION_BODY The name of the parameter.
Whether the parameter is required.
The JsonSchema definition of the parameter. This typically includes things like type, description, enum values, format, other restrictions, etc.
The name of the tool, as presented to the model. Must match ^[a-zA-Z0-9_-]{1,64}$.
The tool is guaranteed to be non-mutating, repeatable, and free of side-effects. Such tools can safely be executed speculatively, reducing their effective latency. However, the fact they were called may not be reflected in the call history if their result ends up unused.
Requirements that must be fulfilled when creating a call for the tool to be used.
Security requirements for an HTTP tool.
The options for security. Only one must be met. The first one that can be satisfied will be used in general. The single exception to this rule is that we always prefer a non-empty set of requirements over an empty set unless no non-empty set can be satisfied.
Requirements keyed by name.
An additional special security requirement that can be automatically fulfilled during call creation. If a tool has this requirement set, a token identifying the call and relevant scopes will be created during call creation and set as an X-Ultravox-Call-Token header when the tool is invoked. Such tokens are only verifiable by the Ultravox service and primarily exist for built-in tools (though it's possible for third-party tools that wrap a built-in tool to make use of them as well).
Dynamic parameters that must be overridden with an explicit (static) value.
The static parameters added when the tool is invoked.
Where the parameter is used.
PARAMETER_LOCATION_UNSPECIFIED, PARAMETER_LOCATION_QUERY, PARAMETER_LOCATION_PATH, PARAMETER_LOCATION_HEADER, PARAMETER_LOCATION_BODY The name of the parameter.
The value of the parameter.
The maximum amount of time the tool is allowed for execution. The conversation is frozen while tools run, so prefer sticking to the default unless you're comfortable with that consequence. If your tool is too slow for the default and can't be made faster, still try to keep this timeout as low as possible.
