# Travis CI v3: omit the version header and you get a fake-looking 404

```
GET https://api.travis-ci.com/repo/travis-ci%2Ftravis-build
   (no Travis-API-Version header)
-> HTTP 404, application/json, 20 bytes: {"file":"not found"}

GET https://api.travis-ci.com/repo/travis-ci%2Ftravis-build
   -H "Travis-API-Version: 3"
-> HTTP 200, application/json, 1660 bytes:
   {"@type":"repository","@href":"/repo/4375424", ...
     "@permissions": {"read": true, "settings_read": false, ...} }
```

The no-header response's `{"file":"not found"}` body and key name (`file`,
not `message` or `error`) look like a static-asset router's generic miss, not
an API-level auth/version error — nothing in the body or the `x-` headers
(`x-oauth-scopes`, `x-request-id`) hints that the fix is one header. With the
header present, the endpoint identifies itself via
`x-endpoint: Travis::API::V3::Services::Repository::Find` and returns the
real resource, including a numeric-offset `builds` collection
(`GET /repo/4375424/builds?limit=3` -> `200`, `@pagination.count: 9994`,
`next`/`prev`/`first`/`last` hrefs).

## The legacy `.org` (OSS-only) host is effectively retired

```
GET https://api.travis-ci.org/repo/travis-ci%2Ftravis-build -H "Travis-API-Version: 3"
-> HTTP 404, application/json, 3 bytes: {}
```
Same repo, same header, on the pre-2021 free-OSS host: an empty-object 404,
not even the `{"file":"not found"}` shape `.com` gives for a missing
header — `api.travis-ci.org` answers every path this way now, consistent
with Travis CI's 2020-2021 consolidation of OSS builds onto `.com`.

## The `@permissions` block is present even for a read with no credentials

The `.com` success body's `@permissions` object (`"read": true,
"settings_read": false, "build_restart": false, ...` — eleven boolean flags
total) is returned on a fully anonymous `GET`, every flag `false` except
`read`. This confirms the v3 API always serializes the full permission set
relative to the (anonymous) caller rather than omitting it, which is useful
for a client deciding whether to attempt a write without first trying it:
the read-only anonymous case is self-describing, not just inferred from a
later `403`.
