CodeCogs vs iDigBio

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.

iDigBio is a keyless REST API exposing more than 150 million digitized natural-history specimen records — pressed plants, pinned insects, fossils, and more — contributed by U.S. museums and herbaria under an NSF-funded national digitization effort. Search and summary endpoints return Darwin Core fields (collector, locality, taxonomic name) as JSON, and the same backend powers iDigBio's public specimen-browsing portal.
