Message API

[Jeomon]

Can you please also include the messaging api for the respective provider also like

Nvidia: openai_completions api
Anthropic: anthropic_messages
Openai: openai_responses

// Standard naming of the providers supported api endpoint

like that can you please include ig it can simply the routing logic to the respective provider easily and simpler instead of doing custom mapping in the app builders end.

Please include the api property also in the provider.

This issue needs maintainer review and no automated fix was opened.

The request asks for a new api property to be added to providers (e.g., openai_completions, anthropic_messages, openai_responses) to indicate which API style each provider exposes. This is a feature request to track a new kind of information — it would require schema changes, decisions about classification semantics, and defining values for every provider. It is not a correction to existing model/provider metadata, so it falls outside the scope of automated catalog data fixes.
