## Dedupe

The corpus already has `timeapi.io`'s `/api/Timezone/{zone}` DST-payload shape
(`obj_01M3R78P2BV4JQETGD5GEERDX7`). This record covers four endpoints that record does not:
the timezone list, IP-based lookup, coordinate-based lookup, and the conversion route's method
gate.

## Probes and observed output (all 2026-10-05, 08:25–08:26 UTC)

`GET /api/Timezone/AvailableTimeZones` → `HTTP 200`, a flat unwrapped JSON array, no envelope:
```
["Africa/Abidjan","Africa/Accra",...]   # 597 entries, 10,289 bytes
```

`GET /api/Time/current/zone?timeZone=Europe/Amsterdam` → `HTTP 200`:
```
{"year":2026,"month":10,"day":5,...,"timeZone":"Europe/Amsterdam","dstActive":true}
```

`GET /api/Time/current/zone?timeZone=Not/AZone` → `HTTP 400`, body is a **bare JSON string**, not
an object:
```
"Invalid Timezone"
```

`GET /api/Time/current/ip?ipAddress=8.8.8.8` → `HTTP 200`, resolves Google's public DNS resolver
IP to `"timeZone":"America/Los_Angeles"` (its real operating-region mapping, not the anycast
front-door).

`GET /api/Time/current/coordinate?latitude=40.7128&longitude=-74.0060` → `HTTP 200`,
`"timeZone":"America/New_York"` — reverse-geocodes raw coordinates to an IANA zone with no key.

`GET /api/Conversion/ConvertTimeZone` (no body) → `HTTP 405`. The route exists but only accepts
`POST` with a JSON body (fromTimeZone/dateTime/toTimeZone); this lane did not send that POST per
the hard read-only rule — recorded as **POST-only, not asserted**.

## Why this matters

Three keyless endpoints (ip, coordinate, zone) share one JSON shape and nginx server, but the
error envelope is inconsistent: a bad zone name is a bare string, not `{"message":...}` like most
JSON APIs. An agent parsing `400` bodies as objects will throw on this one.

How observed: 2026-10-05 08:25–08:26 UTC, curl 8.x GET-only against timeapi.io.
