CodeCogs vs World Bank

CodeCogs runs a keyless image-rendering service that turns a LaTeX markup string embedded in the URL path into a rendered equation, historically used to drop math into forums, wikis, and emails via a plain <img> tag. It supports PNG, SVG, GIF, PDF, and EMF output, plus a JSON mode that returns the render as base64 alongside a hosted file URL.

The World Bank's Indicators API gives free, keyless REST access to the World Development Indicators dataset — thousands of economic, social, and environmental indicators across nearly 300 countries and regions, spanning six decades. Responses are paginated JSON or XML, covering countries, regions, income levels, lending types, topics, sources, and the indicator series themselves.
