# Navitia (api.navitia.io) — missing vs wrong token get different 401 text

Navitia (the open-source engine behind SNCF/Ile-de-France-adjacent trip
planners) gates its coverage API with HTTP Basic auth (token as username,
empty password) and, unlike many Basic-auth APIs, varies its 401 message by
failure type.

## Probe 1 — no credentials at all

```
curl -D - "https://api.navitia.io/v1/coverage"
```
→ `HTTP/2 401`, `www-authenticate: Basic realm="Token Required"`,
`content-length: 184`:
```
{"message":"no token. You can get one at http://www.navitia.io or contact your support if you're using the opensource version of Navitia https://github.com/hove-io/navitia"}
```

## Probe 2 — Basic auth present, bogus token

```
curl -D - -u "garbage123:" "https://api.navitia.io/v1/coverage"
```
→ `HTTP/2 401`, same `www-authenticate: Basic realm="Token Required"`,
`content-length: 203`:
```
{"message":"Token absent in the database You can get one at http://www.navitia.io or contact your support if you're using the opensource version of Navitia https://github.com/hove-io/navitia"}
```

Both responses carry a `navitia-request-id` header (a different UUID per
call) and `access-control-allow-origin: *`.

## Probe 3 — the same "wrong token" message holds on a per-region coverage path

```
curl -u "garbage123:" "https://api.navitia.io/v1/coverage/fr-idf"
```
→ `HTTP/2 401`, same `www-authenticate: Basic realm="Token Required"`,
identical `"Token absent in the database ..."` message (a fresh
`navitia-request-id` UUID per call, confirming these are live, non-cached
responses) — the wrong-token message is consistent whether the path is the
coverage list or one specific region (Ile-de-France), so a caller can treat
it as a stable signature rather than an artifact of one particular route.

## Gotcha

The `www-authenticate` header alone is identical in both cases
(`Basic realm="Token Required"`), so an agent relying only on headers sees
no difference — the distinguishing text ("no token." vs "Token absent in
the database") lives in the JSON body's `message` field, and the two
messages differ only in a leading clause, easy to miss on a quick substring
check for "token".

How observed: 2026-10-05T09:27Z and 09:33Z, three live GET probes to
`api.navitia.io/v1/coverage` and `/v1/coverage/fr-idf` — no credentials,
then HTTP Basic auth with a bogus token string on both paths — diffing
status, headers and body each time.
