Dungeons and Dragons vs Universalis

The D&D 5e SRD API (the 5e-bits project) is a fully keyless reference for the System Reference Document — spells, classes, monsters, equipment, races, and rules — queryable through both a REST API and a GraphQL endpoint at the same host. Its old `/docs/` path now redirects to a rebuilt documentation site on GitHub Pages, but the underlying API itself is unchanged and still served over HTTPS from the original `dnd5eapi.co` domain.

Universalis is a crowdsourced market board API for Final Fantasy XIV, aggregating item listings, prices, and sale history submitted by the game's own community-plugin ecosystem across every data center and world. It exposes a keyless REST API alongside a WebSocket feed for real-time listing updates, both free to use. The old `/docs/index.html` path now permanently redirects to a dedicated documentation site.
