News REST API
To use DTN’s web services, you must display DTN’s logo on each page that our information appears. The DTN logo is available here.
If you can and choose to display a DTNPF news article directly on your site, you MUST set a Canonical link reference in the <head> section of your page. Something like this example: <link rel=”canonical” href=”https://www.dtnpf.com/agriculture/web/ag/news/crops/article/2018/12/07/global-phosphorous-market-balanced-2″ />. This href value is available as the dtnpfUrl field in the Article response. This will protect both your and dtnpf.com SEO.
