It’s relatively affordable.

Get the API and integrate it with your blog. Write it to only enable when the API-Key is available. Otherwise, the API should be disabled – this a​llows you to have the API ready for when you’re ready to pay the monthly fees…

Note, there is a FREE version too!Just change the annual pay to $0/yr and they will email the “FREE” API key. There are supposedly limitations on bandwidth and number of queries/month… But for starters, this is great!
