English Random Words vs RandomUser

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.

RandomUser (the Random User Generator) is a free, open-source API that returns one or more fully-formed fake user profiles — name, address, email, login credentials, and photo — as JSON, XML, CSV, or YAML depending on the format query parameter. Requests can be tuned with parameters for results count, gender, nationality, and a seed value that makes the "random" output reproducible across calls. It has no authentication and no key-based rate limit, making it a common stand-in for Lorem Ipsum-style placeholder people in demos and test fixtures.
