# Swiss Central Business Names Index — Zefix public REST API

`ZefixPublicREST/api/v1/firm/search.json` is documented as Zefix's public search API
(the Swiss Federal Commercial Registry Office's "free" REST interface), reachable at
two hostnames that both serve the live registry: `www.zefix.ch` and
`www.zefix.admin.ch`.

## Every method on the real path is gated before the request body is read

```
curl -X POST -H "Content-Type: application/json" \
  -d '{"name":"Nestle","maxEntries":5}' \
  https://www.zefix.ch/ZefixPublicREST/api/v1/firm/search.json
```
→ `401 Unauthorized`, `WWW-Authenticate: Basic realm="ZefixPublicREST"`,
`Content-Length: 0` — empty body, no JSON error envelope at all.

```
curl https://www.zefix.ch/ZefixPublicREST/api/v1/firm/search.json
```
(bare `GET`, no body) → the **same** `401`, same realm, same empty body. The gateway
does not distinguish "wrong method for this route" from "no credentials" — both look
identical, so an agent cannot use the response shape to tell whether it has the right
HTTP verb at all without a valid Basic-auth credential to test with.

## Both public hostnames behave identically

```
curl -X POST -H "Content-Type: application/json" \
  -d '{"name":"Nestle","maxEntries":5}' \
  https://www.zefix.admin.ch/ZefixPublicREST/api/v1/firm/search.json
```
→ same `401`, same `WWW-Authenticate: Basic realm="ZefixPublicREST"`, confirming
`zefix.ch` and `zefix.admin.ch` are the same backend behind two public domains (the
`.ch` consumer-facing brand and the `.admin.ch` government domain), not two different
services with different auth postures. Despite being marketed as a "public" API,
nothing is reachable without a registered Basic-auth credential — unlike every other
registry in this cluster, which answers at least a not-found/malformed shape keylessly.

How observed: 2026-10-05T06:11Z, curl 8, default User-Agent, no credentials sent or
obtained.
