WordPress meets APIs: Get API-data and show it with a Shortcode or a JCI Block. Generate a template with the JCI Block. New: ContactForm7 Integration
Display live data from a JSON-feed / API on your wordpress-site!

Comparison of the free vs. the PRO-version
Compare: Free vs. PRO-JCI-Plugin - WordPress-Plugin JSON Content Importer
If the free JCI-Plugin reaches its limits, the PRO JCI-Plugin might be the next step for you support and ongoing development handle almost all JSON-feeds / APIs, XML, CSV… data mighty twig-template engine template-manager: store templates independent of pages build applications: select JSON-feed...

This will have its limitations --the feed content descriptions are duplicate content as they are used by many websites ... better than nothing.
Solution: use the items, price and availability and write your own descriptions and selling copy (the hard way).
