## Probes

```
GET https://aeroapi.flightaware.com/aeroapi/flights/UAL123
(no x-apikey header)
```

## Observed

HTTP/1.1 401 Unauthorized, `content-type: application/json`, `content-length: 129`,
body:

```json
{"title": "Invalid API key", "reason": "INVALID_API_KEY", "detail": "Provided API key is not valid", "status": 401}
```

Note the wording: the key is simply *absent*, yet the server's `title`/`detail`
describe it as "Invalid"/"not valid" rather than "missing" — AeroAPI does not appear
to distinguish a missing header from a present-but-wrong one at the message level,
only `reason: INVALID_API_KEY` is given either way.

## Compared to other flight-data keyless refusals, same session

Also probed live in this lane: RapidAPI-fronted AeroDataBox
(`aerodatabox.p.rapidapi.com/flights/number/UA123`, no `X-RapidAPI-Key`) returns
HTTP 401 with a single-field generic gateway body,
`{"message":"Invalid API key. Go to https://docs.rapidapi.com/docs/keys for more
info."}`, plus `x-rapidapi-request-id`/`x-rapidapi-version` headers — this is
RapidAPI's own marketplace-gateway error, not an AeroDataBox-specific one, so it
would be identical for any RapidAPI-hosted API given no key. FlightLabs
(`app.goflightlabs.com/flights`) returns HTTP 401 with an even flatter
`{"error":"You need to get your API Key to do API calls."}` — and, unusually for a
stateless REST API, also issues three Laravel session cookies
(`XSRF-TOKEN`, `flightlabs_session`, an attribution-tracking cookie) on a GET that
never authenticated.

## Conclusion

AeroAPI's four-field flat JSON (`title`, `reason`, `detail`, `status`) duplicates the
HTTP status code as a body field (`"status": 401`) — redundant with the actual HTTP
response code but useful for a client that only inspects the parsed body (e.g. after
a proxy normalizes all upstream errors to 200). `reason` is the stable machine key
(`INVALID_API_KEY`); `title`/`detail` are prose variants of the same fact, not
independent information. Compared to the RapidAPI-fronted and FlightLabs refusals,
AeroAPI's is the most structured of the three — the other two give only a bare
`message`/`error` string with no machine-readable code at all.

How observed: 2026-10-05T10:25:20Z, anonymous curl GET(s), no credential sent.
