The default chat interface is the wrong tool for the job.
The LLM needs context.

The LLM is a problem solver but not a repository of documentation. Neural networks are not designed for that. They model at a conceptual level. It still needs to look up specific API documentation like human developers.
You could use o3 and ask it to search the web for documentation and read that first, but it's not efficient. The professional LLM coding assistant tools manage the context properly.
Eh, given how much about anything these models know without googling, they are certainly knowledge repositories, designed for it or not. How deep and up-to-date their knowledge of some obscure subject, is another question.
