Anthropic Models API

Query available models on the OfoxAI platform through the Anthropic native protocol. The response format follows the Anthropic API specification (type, display_name, created_at, etc.).

The Models API is a public endpoint that does not require an API Key. This endpoint returns all models accessible via the Anthropic protocol, not limited to the Claude series.
