You should run a simple query to find all opreturns throughout the blockchain and display the topX results in a cloud on your site https://github.com/jasondavies/d3-cloud/
*Most frequent words in opreturn. Nice work! You could break it up on a monthly or even daily basis too. Also get a new API key and don't publish it or someone will take advantage🙃
No way new API key to be any good, because I run the queries to Bitdb in the browser. An option to link api key to domain would be good
