Check if a model provider is registered in the gateway’s cache.
This is a lightweight endpoint that only checks the gateway’s internal state,
without making any requests to the actual provider backend. Use this to verify
the gateway is ready to route requests to a provider after deployment.
Returns:
200 OK with provider info if the provider is registered
404 Not Found if the provider is not yet in the gateway’s cache
