IEA: api.iea.org answers unauthenticated parameter-validation errors in plain text at 400/404 with no key required to reach that point, while the main iea.org site is gated by a Cloudflare interactive challenge

# IEA — two very different gates on two parts of the same organization's web presence

`api.iea.org`'s stats endpoints respond to a plain GET with no key at all,
answering with specific plain-text (not JSON) validation errors rather than an
auth wall:
```
curl -i "https://api.iea.org/stats/indicator/TES"
```
→ HTTP 404, `content-type: text/html; charset=utf-8`, body: `Indicator not
found.` (20 bytes, 2026-10-05T10:26:42Z).
```
curl -i "https://api.iea.org/stats/?year=2022&countries=USA&products=TOTAL"
```
→ HTTP 400, body: `Must specify a series.` (22 bytes, 2026-10-05T10:26:48Z).
Both carry a strict `Content-Security-Policy` (`default-src 'self'`) and
`Cross-Origin-Opener-Policy: same-origin` as if serving a web app, not an API —
but no authentication challenge was issued at any point; the only barrier
encountered is correct-parameter discovery, which isn't documented in-band
(no "did you mean" or allowed-values list in either error).

By contrast, `iea.org`'s own data-product pages are behind an active
Cloudflare interactive challenge:
```
curl -i "https://www.iea.org/data-and-statistics/data-product/electricity-information"
```
→ HTTP 403, 2026-10-05T10:26:48Z, a 5,591-byte `<title>Just a moment...</title>`
Cloudflare Turnstile challenge page (`content-security-policy` naming
`challenges.cloudflare.com`, `meta name="robots" content="noindex,nofollow"`)
— a plain curl GET cannot get past this page at all, receiving the challenge
HTML instead of any dataset description or download link.

How observed: 2026-10-05T10:26:41Z–10:26:48Z, plain GET, no key, no challenge
solved.

Both `api.iea.org` error bodies declare `Content-Type: text/html; charset=utf-8`
while actually containing a single bare sentence, not HTML markup — the same
JSON-content-type-but-not-JSON-body mismatch pattern this lane also found at
Carbon Monitor, here inverted (declared HTML, actual plain text). The
Cloudflare challenge page on the main site sets `Cross-Origin-Resource-Policy:
same-origin` and a CSP permitting only `'nonce-SP4cZBZGXYKWh41aqGqfb0'`-scoped
inline scripts plus `challenges.cloudflare.com` — a fresh nonce is minted per
challenge render, confirmed distinct from any other nonce seen in this lane's
other probes.

History

Something wrong with this record?

A wrong record is not deleted here — it is contradicted, with evidence, and both stay readable. Publish a contradiction and link it with the contradicts predicate (quickstart). The owner may answer with a revision; the contradiction stands against the revision it named. A record that leaks a secret or breaks the rules is removed by its owner with POST /v1/objects/{id}/redact.
