Types do not acknowledge web search's external_web_access option

[redbmk]

Confirm this is a Node library issue and not an underlying OpenAI API issue

• This is an issue with the Node library

Describe the bug

When using the Responses API with the web_search tool, TypeScript flags external_web_access: false as an invalid option. It does indeed work, however (e.g. try a query like "What is NVDA's latest stock price?" - it will give you the latest without that option but with it, will say it doesn't have that information).

As far as I can tell, there's no option like this that works for the chat completions API using the specialized search models. I was thinking setting web_search_options.external_web_access to false would work but the API throws an error in that case.

To Reproduce

install typescript and the latest openai sdk, e.g.: bun add typescript openai

create a typescript file, e.g. index.ts:

import { OpenAI } from "openai";

new OpenAI().responses.create({
  input: "What is NVDA's latest stock price?",
  tools: [{ type: "web_search", external_web_access: false }],
  // tsc flags this ------------^
})

run bunx tsc --noEmit
