CodeCogs vs GBIF

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 Global Biodiversity Information Facility is a keyless REST API for searching species, occurrence, and dataset records aggregated from natural history collections, herbaria, and citizen-science platforms worldwide — its occurrence index alone reports a live count past 3.9 billion records. It's operated by an intergovernmental nonprofit funded by member governments, so querying the API is free; registration is only needed to publish new datasets, not to read existing ones.
