​
Authorization
string
header
required

Bearer authentication header of the form Bearer <token>, where <token> is your auth token.

Body

application/json
​
key
string
required

A unique identifier for the agent. This key must be unique within the same workspace and cannot be reused. When executing the agent, this key determines if the agent already exists. If the agent version differs, a new version is created at the end of the execution, except for the task. All agent parameters are evaluated to decide if a new version is needed.

Minimum length: 1
​
model
string
required

The language model that powers the agent. The model must support tool calling capabilities.

​
role
string
required

Specifies the agent's function and area of expertise.

Minimum length: 1
​
instructions
string
required

Provides context and purpose for the agent. Combined with the system prompt template to generate the agent's instructions.

Minimum length: 1
​
message
object
required

The A2A format message containing the task for the agent to perform.

​
path
string
