Useful for fetching large sets of results

Example code using requests library

  api.fetch(query, {count: count})
  try:
      with requests.get(url, stream=True) as r:
          r.raise_for_status()
          with open(output_file, "wb") as f:
              for chunk in r.iter_content(chunk_size=8192):
                  if chunk:  # filter out keep-alive chunks
                      f.write(chunk)
  except requests.exceptions.HTTPError as e:
      print(f"HTTP error {r.status_code} while downloading {url}")
  except requests.exceptions.RequestException as e:
      print(f"Request failed for {url}")
