50 Things Anthropic's API Can't Do (And We're Going to Walk Through Every Single One)

Quick disclaimer before we start: Claude helped me write this. Very intentionally. Not just "helped," either. I gave Claude direct access to our docs at docs.backboard.io. It navigated the docs itself, read them, and produced this list. So yes, an AI made by Anthropic read our documentation and wrote about the limitations of Anthropic's own API. It did not argue. It did not resist. Because it knows. So let's talk about what it knows. Anthropic's API is stateless. So is OpenAI's. So is Grok. So is OpenRouter. That one word, stateless, explains almost every pain point developers hit the second they move beyond a toy demo. And yes, we solve this at Backboard. You get free state for life, by the way. Not to bury the lead. But that is only part of the story. Here is the bigger point. Stateless means every API call starts from zero. The model does not know who you are. It does not know what was said five minutes ago. It does not know what your user cares about. It does not know what happened
