Endpoint: POST /v2/tool

This endpoint allows you to create new tools from an OpenAPI schema. These tools are used by agents to access external APIs. A user must provide the OpenAPI schema, and the system will register the tool and return the tool IDs.

​
Query-String Parameters

​
user_id
string
required

The unique ID of the user creating the tool.

​
Parameters

​
schema
object
required

The OpenAPI schema defining the tool’s structure.

You can generate your OpenAPI schema here, which defines the structure and functionality of your tool in a standardized format.
