KEMP.REST / EXAMPLES / CODE

Code

Written by Kevin Kemp. Samples from the past year. AI SEO is the first group: the page builder, schema, llms.txt, and AI Overviews. Offing: Following Seas is next: the technical report, then the AIS, NOAA, and OpenStreetMap integrations. The other groups are here so the index can keep growing. Each page explains the problem, names the technology in that file, and puts the source at the bottom.

Across these files: HTML, CSS, and JavaScript, JSON and JSON-LD, PHP, WordPress, WooCommerce, WooRewards, AffiliateWP, Advanced Custom Fields, MySQL, REST APIs, WebSockets, Canvas, OAuth, Auth0, Laravel, Blade, Eloquent, WHMCS, cURL, the WordPress AI client, OpenAI, Anthropic, Google Cloud, Google Business Profile, Google Maps, DataForSEO, AISStream, NOAA, and OpenStreetMap.
