SerpAPI vs OpenAI web_search
OpenAI's web_search tool is SerpAPI wearing a ChatGPT jersey -- OpenAI disclosed the partnership in 2024 and the cost structure confirms the markup. This comparison is really one question: should you call SerpAPI directly or pay OpenAI to call it for you? The answer depends on how much you value tool-use ergonomics versus per-call cost.

Feature-by-feature comparison
The verdict
If you're going to use SerpAPI anyway, call it directly. The OpenAI web_search convenience tax is real and silent. The only reason to use OpenAI's wrapper is if your agent lives entirely inside Assistants and the ergonomics outweigh the cost.
Consider Scavio instead
