What's the best way to manage multiple AI API providers (OpenAI, Midjourney, etc.) on a DigitalOcean-hosted app?

Posted on June 3, 2026

I’m building an AI-powered app hosted on a DigitalOcean Droplet. The app needs to call multiple providers — OpenAI for LLMs, Midjourney for image generation, and some video generation models like Kling and Veo 3.

Managing separate API keys, rate limits, and billing across all of them is getting messy. I’ve been looking at API aggregator platforms that unify everything under one endpoint — I came across CometAPI which seems to cover 500+ models including Midjourney (which is hard to find via API these days), all OpenAI-compatible.

Has anyone used an aggregator like this in production on DigitalOcean? Curious about:

  • Latency impact vs calling providers directly
  • How you handle failover if the aggregator goes down
  • Whether the cost savings (CometAPI claims ~20% off official rates) actually hold up at scale

Any experience or alternative approaches welcome.
