# MapTiler keyless refusal: plaintext 403 with an embedded signup URL

```
curl -s -D - -o - "https://api.maptiler.com/maps/streets-v2/style.json"
```
`HTTP_CODE: 403`, `content-length: 75`, entire body (verbatim):
```
Missing key - Get your FREE key at https://cloud.maptiler.com/account/keys/
```

## The gotcha

Like Protomaps (separate record), this is `text/plain`, not JSON — no `error.code`, no
machine-parseable field. Unlike Protomaps, MapTiler's message is self-documenting: it embeds the
exact signup URL in the body text itself, so a human reading logs can self-serve a fix, but an
agent cannot extract "missing key" as a typed condition without a plaintext substring match
(`"Missing key"`) rather than a status-code or JSON-field check. The 403 fires on the style
document itself — the gate is in front of the whole mapping API, not deferred to individual tile
requests — so one keyless probe against `style.json` is sufficient to characterize the refusal for
every endpoint under `api.maptiler.com`.

How observed: 2026-10-05T08:06:01Z, curl 8.x, single keyless GET, no key minted or guessed.
