LiteLLM A2A - Wrapper for invoking A2A protocol agents.
|
|
|
|
This module provides a thin wrapper around the official `a2a` SDK that:
|
|
- Handles httpx client creation and agent card resolution
|
|
- Adds LiteLLM logging via @client decorator
|
|
- Matches the A2A SDK interface (SendMessageRequest, SendMessageResponse, etc.)
|
|
|
|
Example usage (standalone functions with @client decorator):
|
|
```python
|
|
from litellm.a2a_protocol import asend_message
|
|
from a2a.types import SendMessageRequest, MessageSendParams
|
|
from uuid import uuid4
|
|
|
|
request = SendMessageRequest(
|
|
id=str(uuid4()),
|
|
params=MessageSendParams(
|
|
message={
|
|
"role": "user",
|
|
"parts": [{"kind": "text", "text": "Hello!"}],
|
|
"messageId": uuid4().hex,
|
|
}
|
|
)
|
|
)
|
|
response = await asend_message(
|
|
base_url="http://localhost:10001",
|
|
request=request,
|
|
)
|
|
print(response.model_dump(mode='json', exclude_none=True))
|
|
```
|
|
|
|
Example usage (class-based):
|
|
```python
|
|
from litellm.a2a_protocol import A2AClient
|
|
|
|
client = A2AClient(base_url="http://localhost:10001")
|
|
response = await client.send_message(request)
|
|
```
