RandomUser
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.
RandomUser is a free, keyless 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. A live probe this run confirmed `seed=` output is fully reproducible byte-for-byte across separate requests, and that an unpinned request silently tracks the newest schema (`version 1.4`) rather than a fixed one.

- No API key or signup required for any call. Every response echoes `access-control-allow-origin: *` regardless of whether an `Origin` header is sent, so browser-side calls need no proxy; the only planning gotcha is pinning behavior (schema version, result count), not authentication.
Your key is stored only in this browser (localStorage) and sent directly to the API — never to greatapis.

Gotchas & limits
- `seed=` output is genuinely reproducible, not just similar: two back-to-back live `GET /api/?seed=greatapis` calls this run returned byte-identical response bodies -- safe to use as fixed fixture data in tests.
- Requesting more than 5,000 results doesn't error or clamp at a round number -- it silently falls back to exactly 1 result instead: a live `GET /api/?results=6000` this run (and three repeat attempts) all returned a single-element `results` array in well under 100ms, far too fast to have actually generated the requested count. `results=500` and `results=5000` both work as expected, so the cliff sits between 5,000 and 6,000.
- `results=0` is not 'return nothing' -- it's treated the same as omitting the parameter and returns exactly 1 result, confirmed live this run.
- An unpinned request silently tracks the newest schema: the `info.version` field in every response above reads `"1.4"` with no version requested; pin `/api/1.3/` (or whichever version) in the path if a schema change would break a downstream test.
- `format=csv` (and `xml`/`yaml`) changes the wire format but not the field set: a live `GET /api/?format=csv&results=1` this run returned the same dotted-path fields (`name.first`, `location.city`, ...) as flattened CSV columns, including a Finnish `id.value` of the literal string `NaNNA456undefined` when the generated nationality has no real national-ID scheme -- don't assume `id.value` is always numeric or even well-formed.
