Steps

1. Create file in api/v1/endpoints/ or edit existing
2. Define Pydantic request/response schemas
3. Create async endpoint functions with type hints
4. Include tags=["Category"] for OpenAPI grouping
5. Register router in api/v1/__init__.py

Router Registration

In apps/artagent/backend/api/v1/__init__.py:

from apps.artagent.backend.api.v1.endpoints import my_module

api_router.include_router(
    my_module.router,
    prefix="/my-resource",
    tags=["MyResource"],
)

Common Patterns

Access App State

@router.get("/resource")
async def get_resource(request: Request):
    redis = request.app.state.redis_client
    # Use redis...

Path Parameters

@router.get("/resource/{resource_id}")
async def get_resource(resource_id: str) -> MyResponse:
    ...

Query Parameters

@router.get("/resources")
async def list_resources(
    limit: int = 10,
    offset: int = 0,
) -> list[MyResponse]:
    ...

Error Handling

@router.get("/resource/{id}")
async def get_resource(id: str) -> MyResponse:
    resource = await fetch_resource(id)
    if not resource:
        raise HTTPException(status_code=404, detail="Resource not found")
    return resource

OpenAPI Tags

Use consistent tags:

• Health - Health/readiness endpoints
• Calls - Call management
• Agents - Agent operations
• Voice - Voice/speech operations
• Sessions - Session management

Schema Location

For reusable schemas, add to api/v1/schemas/:

# api/v1/schemas/my_schemas.py
from pydantic import BaseModel

class SharedSchema(BaseModel):
    field: str

For models with timestamps/IDs, extend base:

from apps.artagent.backend.api.v1.models.base import BaseModel

class MyModel(BaseModel):
    field: str
    # Automatically gets id, created_at, updated_at
