Open Library vs Wizard World
Open Library, an Internet Archive project, exposes its book catalog for search, work/edition/author lookups by identifier, subjects, and public reading lists, returned as JSON, YAML, or RDF/XML, with a separate Covers API serving cover art by ISBN or Open Library ID. No API key is required, though sending a descriptive User-Agent and contact email triples the default 1-request-per-second anonymous rate limit. Bulk access is deliberately kept off the live API — the project publishes free monthly data dumps for that instead.
A community-run REST API mirroring the Harry Potter Wiki: houses (with founders, ghosts, and heads), wizards, spells, elixirs, ingredients, and magical creatures, each returned as detailed JSON. Built and maintained by a small volunteer team (MossPiglets) on .NET/ASP.NET Core with a public Swagger spec, hosted free on Heroku with no key, account, or documented rate limit beyond the dyno's own capacity.
