After growing from OpenAI-only to Anthropic, Gemini, DeepSeek, and Qwen plus an image model, the team juggles five dashboards, invoices, and key sets. Core requirements: one OpenAI-compatible endpoint, per-key spend limits to stop runaway agents, automatic fallback on 529s, and a single invoice.

Options evaluated: LiteLLM (self-hosted, solid, but needs an owner), Portkey, OpenRouter, and llmapi.ai (pay-as-you-go at provider list prices). The author is most curious how these gateways' fallbacks behave in production.
