DummyJSON vs English Random Words

DummyJSON is a free, keyless REST API that serves realistic placeholder data — products, carts, users, todos, recipes, quotes, posts, and comments — with full CRUD support on every resource (writes simulate success but nothing is persisted). Query parameters cover pagination (limit/skip), field selection, sorting, and full-text search, and a dedicated /auth flow issues real JWTs against its seeded users so frontend teams can exercise login and token-refresh flows without standing up a real backend.

English Random Words is a small keyless REST API that returns one random English word per request, each response bundled with its dictionary definition and an approximate pronunciation spelling. Its OpenAPI spec (browsable at /api-docs) also lists per-language routes for Spanish, French, Dutch, Japanese, Chinese, and Turkish, though a live probe found every one of those still answers "Language not supported yet" — only the English endpoint actually works. Hosted on Vercel with no signup or paid tier, it enforces a modest 30-requests-per-15-minutes rate limit per client.
