## Coverage
IAEA NUCLEUS is the agency's unified portal linking its various databases (PRIS, INIS, and others); INIS (International Nuclear Information System) is the bibliographic/full-text repository reachable from it. Neither exposes a keyless REST API discoverable by GET in this probe.

## Access

**INIS search.** `GET https://inis.iaea.org/search/search.aspx?q=nuclear+reactor` → **403**, `text/html; charset=UTF-8`, 5,505 bytes, `<title>Just a moment...</title>` — a full Cloudflare managed-challenge interstitial. Response headers confirm it explicitly: `cf-mitigated: challenge`, `server: cloudflare`, a `cf-ray` id, and a strict inline CSP scoped to `challenges.cloudflare.com`. This is Cloudflare's JavaScript-execution challenge, not a simple IP/UA block — no static header or UA change bypasses it; it requires running the challenge script.

**NUCLEUS.** `GET https://nucleus.iaea.org/` → **302**, `Location: https://nucleus.iaea.org/Pages/default.aspx` — a SharePoint site (the `/Pages/*.aspx` path convention gives it away). `GET https://nucleus.iaea.org/api/search?q=reactor` (a guessed REST path) → **404**, `text/html`, 655 bytes — but the body is not a generic 404: it is a SharePoint error page containing an inline `<script>` that does `window.location.replace("https://nucleus.iaea.org/Pages/PageNotFoundError.aspx?requestUrl=...api/search")` — the "404" is actually a 200-shaped client-side-redirect page served with a 404 status, requiring JavaScript execution to reach the human-readable error page.

## Auth
Not reached on either host.

## Rate limits
Not observed.

## Freshness
Not observable.

## Known gaps
- No JSON/XML API was reached on either host via GET; this is recorded as the refusal shape actually observed (a JS challenge on one, a SharePoint client-redirect 404 on the other), not as proof neither has a real API elsewhere.
- The two refusals are meaningfully different for an automated client: INIS's Cloudflare challenge is a well-known shape many HTTP libraries recognize by the `cf-mitigated` header or the `Just a moment...` title; NUCLEUS's SharePoint redirect-via-404 is idiosyncratic and easy to mistake for "page doesn't exist" rather than "wrong path under a SharePoint site".

How observed: 2026-10-05T09:19:14Z–09:19:15Z, curl 8.x, UA `pwx-scout/1.0`, direct HTTPS against `inis.iaea.org` and `nucleus.iaea.org`, GET only.
