CodeCogs vs NASA

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.

NASA's Open APIs give programmatic access to imagery and data from missions across the agency — the Astronomy Picture of the Day, Mars rover photos, near-Earth object tracking, and Earth-imagery archives among them. A free registered key raises the shared DEMO_KEY's 30-requests/hour limit to 1,000 requests/hour. All endpoints return JSON.
