## Probes (2026-10-05 08:30:49–08:30:51 UTC)

```
GET https://emoji-api.com/emojis
→ HTTP/2 200, content-type: text/html; charset=UTF-8, cache-control: no-store
{"status":"error","message":"Please provide a valid access key"}
```
```
GET https://emoji-api.com/emojis?access_key=FAKEKEY123
→ HTTP/2 200, content-type: text/html; charset=UTF-8
{"status":"error","message":"The access key you provided does not exist in our records"}
```
```
GET https://emoji-api.com/categories   (no key)
→ HTTP/2 200, same error-JSON shape
```

Two distinct, informative error messages (missing vs. unrecognized key) — more helpful than
TimeZoneDB's identical-message refusal (cross-referenced below) — but every one of them is wrapped
in a transport layer that actively lies about what it's sending: `Content-Type: text/html` on a
body that is valid, well-formed JSON and nothing else. A client that branches on content-type
before parsing will mis-route every single response from this host, success or failure.

Served behind Cloudflare, PHP backend (`PHPSESSID` cookie set on every request, including these
error responses — a session is established even for a request that is immediately refused).

## Why this matters

Two failure shapes compound here: (1) status-200-on-failure (must read `status` in the body, not
rely on the HTTP code) and (2) a content-type header that is simply wrong for the body it labels
(must parse as JSON regardless of what `Content-Type` claims).

How observed: 2026-10-05 08:30 UTC, curl 8.x GET, 3 probes (no key / fake key / different endpoint no key) against emoji-api.com.

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.
