English Random Words vs RoboHash

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.

RoboHash turns any string — an email address, IP, username, or filename — into a deterministic robot, monster, human, or cat avatar, so the same input always renders the same image. Six selectable sets (robots, monsters, robot heads, cats, human avatars, gorillas) each support size, background (bgset), and Gravatar-based seeding, and images are served directly from the URL by file extension in PNG, JPG, GIF, or BMP. No signup, key, or request body is required, and outputs are freely embeddable under a CC-BY license.
