A script consumes an API that returns paginated results with a `Link` header. The header includes `rel="next"` and `rel="last"` links. The developer wants to fetch all pages. What is the safest termination condition?

Continue for a fixed number of iterations equal to the number of items in the first page.

Continue until the response body is empty.

Continue while a `rel="next"` link is present in the response.

Continue until the `rel="last"` link is reached.

When iterating through a page-based API, how do you determine that you have retrieved all available data?

When the HTTP status code is 204 No Content

When the current page number equals the total number of pages

When the server returns a 404 Not Found

When the response body is empty
