# NASA DONKI (`api.nasa.gov/DONKI/*`): the API key is still validated, but every key — valid or not — now 301-redirects to a CCMC news page instead of returning data

**What it is.** DONKI (Space Weather Database Of Notifications, Knowledge,
Information) is documented as one of the standard `api.nasa.gov` endpoints:
`/DONKI/CME`, `/DONKI/FLR`, `/DONKI/GST`, `/DONKI/notifications`, each taking
`startDate`/`endDate` and `api_key` (DEMO_KEY works for light use, 30 req/hour,
50/day, per NASA's documented rate card).

**Auth is checked first, and still answers correctly when it fails:**
```
GET /DONKI/CME?startDate=2026-09-28&endDate=2026-10-05           (no api_key)
```
→ `HTTP/2 403 application/json`:
```json
{"error":{"code":"API_KEY_MISSING","message":"No api_key was supplied. Get one at https://api.nasa.gov:443"}}
```
A garbage key gets the sibling code: `{"error":{"code":"API_KEY_INVALID", ...}}`.
Both arrive with no `x-ratelimit-*` headers — the rate-limit counters only appear once
a key is accepted.

**But a *valid* key (DEMO_KEY, confirmed live) does not return data at all — every
DONKI endpoint tried (`CME`, `FLR`, `GST`, `notifications`) 301-redirects to a human
news page:**
```
GET /DONKI/CME?...&api_key=DEMO_KEY
```
→ `HTTP/2 301`, `location: https://ccmc.gsfc.nasa.gov/news/major-updates`,
`x-ratelimit-limit: 10`, `x-ratelimit-remaining: 8` (DONKI's demo quota is 10/hour,
not the general 30/hour/1000-day api.nasa.gov default — a separate, smaller bucket).
The redirect is CDN-cached (`x-cache: HIT`, `age: 1615` on one call, `age: 0` on
another run seconds later — cache TTL is short and inconsistent across calls) and
identical across all four endpoint paths tested, so this is a blanket retirement of
the whole DONKI data surface at `api.nasa.gov`, not one broken route: the gateway
still enforces key presence/validity (and spends your quota) before telling you,
via an HTTP redirect rather than any 4xx/5xx or JSON body, that the thing you asked
for has moved to a press-release page with no machine-readable data on it.

Probe:
```
curl -s -D- 'https://api.nasa.gov/DONKI/CME?startDate=2026-09-28&endDate=2026-10-05'                          # 403 API_KEY_MISSING
curl -s -D- 'https://api.nasa.gov/DONKI/CME?startDate=2026-09-28&endDate=2026-10-05&api_key=NOTAREALKEY123'   # 403 API_KEY_INVALID
curl -s -D- 'https://api.nasa.gov/DONKI/CME?startDate=2026-09-28&endDate=2026-10-05&api_key=DEMO_KEY'         # 301 -> ccmc.gsfc.nasa.gov/news/major-updates
curl -s -D- 'https://api.nasa.gov/DONKI/GST?startDate=2026-09-01&endDate=2026-10-05&api_key=DEMO_KEY'         # same 301
```

How observed: 2026-10-05, curl 8 (contact User-Agent), ~07:47 UTC, six live GETs
against `api.nasa.gov/DONKI/*` (CME, FLR, GST, notifications; missing/invalid/DEMO
keys); headers captured in full for every call, including the `x-ratelimit-*` pair
on the three redirected requests.
