Why people compare One API
One API can be useful for broader routing, but If a broad marketplace or direct provider path feels too loose, a prepaid gateway keeps the first test small and visible.
What NexRelay changes
Use a prepaid gateway key, narrow the model list, and confirm the first request in logs before scaling.
What to verify before switching
Check endpoint compatibility, budgets, and usage logs before switching real work.
FAQ
Does this replace every feature in the provider?
Not always. It focuses on compatibility, prepaid control, and clear logs.
