JSON Parse Errors in `searchAndContents`

[rohrz4nge]

Hey there! When using the exa js sdk like this:

await exa.searchAndContents(prompt, {
  type: "auto",
  useAutoprompt: true,
  numResults: 10,
  text: true,
  highlights: true,
  livecrawl: "always",
});

we're seeing these errors:

SyntaxError: Unexpected end of JSON input
    at JSON.parse (<anonymous>)
    at parseJSONFromBytes (node:internal/deps/undici/undici:5738:19)
    at successSteps (node:internal/deps/undici/undici:5719:27)

We're running on node v23.6.0 and exa-js 1.9.3

Our guess is that this is a rate limit issue. I doubt it's a direct issue with this sdk but if you could add a function that just returns the plain text instead of the JSON parsed object it would help us tremendously (even better if it would differentiate between errors returned from the api) :)
