Whenever you make an API call using /v2/search or /v2/latest_headlines endpoints*,* we give you key information about your search. Here is an example of a search API call:

curl -XGET 'https://api.newscatcherapi.com/v2/search?q="Elon%20Musk&countries=in,GB&from=13%20days%20ago&page_size=50&page=1' -H 'x-api-key: your_key_1'

The output:

    "status": "ok",
    "total_hits": 1300,
    "page": 1,
    "total_pages": 26,
    "page_size": 50,
    "articles": [ ...

total_hits tells you how many articles are found.

total_pages indicates how many API calls you will have to make in order to get these articles.

One API call can bring a maximum of 100 articles.

You can increase the page_size parameter for your search to make fewer calls and get more data.

curl -XGET 'https://api.newscatcherapi.com/v2/search?q="Elon%20Musk&countries=in,GB&from=13%20days%20ago&page_size=100&page=1' -H 'x-api-key: your_key_1'

gives

    "status": "ok",
    "total_hits": 1300,
    "page": 1,
    "total_pages": 13,
    "page_size": 100,
    "articles": [ ...

Based on the information above, we can say that given the page_size and being on the 1st page, we are seeing all found articles from 1 to 100 out of 1300.

By incrementing the page parameter to 2, I will get all articles from 101 to 200 out of 1300. You get the logic.

To summarize, your goal is to iterate through all found pages and extract articles.

The whole process should be divided into 2 parts:

  • Make 1 call and identify the total number of pages in total_pages
  • Increment page input until the total_pages value to get all articles.

Python (SDK)

The Python library can be installed using pip install launched from the terminal. You can find all the details either on PyPi website or our GitHub Repository.

pip install newscatcherapi

When installed, the package can be directly called from the Python application.

We prepared separate functions get_search_all_pages and get_latest_headlines_all_pages to simplify the process of extracting all articles.

from newscatcherapi import NewsCatcherApiClient

newscatcherapi = NewsCatcherApiClient(x_api_key='your_key_1')

# /v2/search Endpoint
all_articles = newscatcherapi.get_search_all_pages(
                                         q='\"Elon Musk\"',
                                         from_='13 days ago',
                                         countries='IN,GB',
                                         page_size=100,
                                         page=1)

Python (requests)

# Preinstalled packages

# Default packages

# URL of our News API
base_url = "https://api.newscatcherapi.com/v2/search"

# Your API key

# Put your API key to headers in order to be authorized to perform a call
headers = {"x-api-key": X_API_KEY}


# Variable to store all found news articles

# Ensure that we start from page 1
params['page'] = 1

# Infinite loop which ends when all articles are extracted
while True:

    # Wait for 1 second between each call
    time.sleep(1)

    # GET Call
    response = requests.get(base_url, headers=headers, params=params)
    results = json.loads(response.text.encode())
    if response.status_code == 200:
        print(f'Done for page number => {params["page"]}/{results["total_pages"]}')


        # Storing all found articles
        if not all_news_articles:
            all_news_articles = results
        else:
            all_news_articles['articles'].extend(results['articles'])

        # Ensuring to cover all pages by incrementing "page" value at each iteration
        params['page'] += 1
        if params['page'] > results['total_pages']:
            print("All articles have been extracted")
            break
        else:
            print(f'Proceed extracting page number => {params["page"]}')
    else:
        print(results)
        print(f'ERROR: API call failed for page number => {params["page"]}')
        break

print(f'Number of extracted articles => {str(len(all_news_articles))}')
