If you've built anything with OpenAI or Anthropic APIs, you've probably hit this wall:

• Rate limit errors when your app actually gets traffic

• Regional blocks cutting off users in certain countries

• One provider goes down and your whole product goes dark

• Bills that don't match your actual usage

The root problem: single-provider dependency.

The fix is routing traffic through a relay that automatically switches providers, normalizes API formats so your code doesn't change, and lets you pre-load credits instead of watching a monthly bill spike.

That's what NexusAPI does. Drop-in replacement for OpenAI's base URL — your existing code works out of the box.
