Hi Stephen,
If you imported the information you received from a request to our API into a spreadsheet, you would have rows of information. The number of rows depends on the request you make. If you ask for 200 links from our Top Back Links API, then you’ll get 200 rows of information about backlinks. If you submit a single URL to our Page Metrics API, then you’ll get one row of information back from the API. That row of information would include page metrics about the URL. If you do a batch request to the Page Metrics API and submit 5,000 URLs, then you’ll receive 5,000 rows of information about the URLs you submitted. The number of rows you get back from your request depends on which API you’re using and the amount of information you ask for in your request. You only pay for rows of information you actually receive.
Thanks,
Joel.
