  description: 'Best-effort OpenAPI 3.1 description of Cloudflare AI Gateway, covering

    the unified provider proxy endpoint at gateway.ai.cloudflare.com and the

    management plane under api.cloudflare.com/client/v4/accounts/{account_id}/ai-gateway.

    The proxy forwards LLM calls in each provider''s native format and applies

    analytics, caching, rate limiting, retries, fallback, and guardrails. The

    management API lists, creates, updates, and deletes gateways and reads

    request logs.
