Adding Your Own Provider

Extend BaseProvider in providers/ to add support for other APIs:

from providers.base import BaseProvider, ProviderConfig

class MyProvider(BaseProvider):
    async def complete(self, request):
        # Make API call, return raw JSON
        pass

    async def stream_response(self, request, input_tokens=0):
        # Yield Anthropic SSE format events
        pass

    def convert_response(self, response_json, original_request):
        # Convert to Anthropic response format
        pass
