Why AI API Aggregators Often Beat Going Direct to Providers Like OpenAI or DeepSeek

A tech advisor who once urged founders to access AI models directly from providers like OpenAI and DeepSeek has reversed that stance after witnessing real-world friction. One team lost three weeks attempting to register with a Chinese AI provider that required a local phone number and accepted only WeChat Pay or Alipay. The author argues that the traditional 'enterprise vs. startup' framing around AI APIs is a false divide, since both types of teams share overlapping technical needs such as model flexibility, uptime, and compliance. Unified API layers, which aggregate over 180 models behind a single endpoint and accept standard payment methods, are presented as a practical solution for teams of any size. The core argument is that the time and complexity saved by using an aggregator typically outweighs any marginal cost advantage of going directly to individual providers.
