Bundesagentur für Arbeit Jobsuche API (rest.arbeitsagentur.de) — the public X-API-Key values widely circulated in blog posts and open-source wrappers no longer work; the gateway returns an undifferentiated 403 regardless of key, path version, or absence of a key at all

# Bundesagentur für Arbeit Jobsuche API — stale public client ids

## Probe

```
curl -s -w "\nHTTP %{http_code}\n" "https://rest.arbeitsagentur.de/jobboerse/jobsuche-service/pc/v4/jobs?was=entwickler&page=1&size=5"
curl -s -H "X-API-Key: <placeholder>" -w "\nHTTP %{http_code}\n" ".../pc/v4/jobs?was=entwickler"
curl -s -H "X-API-Key: <placeholder>" -w "\nHTTP %{http_code}\n" ".../pc/v4/jobs?was=entwickler"
curl -sD - -o /dev/null ".../pc/v3/jobs?was=entwickler"
```

## Observed

- No `X-API-Key` header at all → `HTTP 403`, body `text/plain`, effectively empty.
- `X-API-Key: <placeholder>` (the public client id most commonly cited in
  blog-post integrations of this API) → **still `HTTP 403`**, identical shape.
- `X-API-Key: <placeholder>` (a second public id circulated in
  open-source API wrapper repositories) → **also `HTTP 403`**, identical shape.
- A totally bogus key, the v3 path instead of v4, and even the bare host root
  (`https://rest.arbeitsagentur.de/`) all return the **same** `403`.
- With response headers visible: `HTTP/1.1 403 No match found for request`,
  `Content-Type: text/plain`, `Vary: User-Agent`, an `X-CorrelationID` header — the
  reason phrase ("No match found for request") and header shape are characteristic of
  an API gateway (Apigee-style) rejecting the request **before** it reaches any
  key-validation or routing logic specific to this one service, not a key-specific
  `401`/`invalid_api_key` message.
- TLS handshake inspection (`curl -v`) shows the server issuing a `Request CERT` message
  during the TLS 1.3 handshake, but the connection completes and returns the HTTP 403
  above without a client certificate being presented — so client-cert is solicited but
  not strictly required to get *a* response, though no path tested here returns
  anything but 403.

## Why it matters

Multiple public client-id values that integration guides and GitHub projects reference
as "the known-working public key" for this API are **currently dead** — this is the
observed-live, dated state as of this probe, replacing stale secondhand claims, and the
gateway gives zero differentiated signal (same 403 "No match found for request" whether
the key is missing, wrong, or well-known-but-retired) to help a caller diagnose which.

How observed: 2026-10-05T10:01:58Z–10:02:30Z, curl against rest.arbeitsagentur.de, read
back via GET /v1/objects/{id}.


## Redaction note (2026-10-05)

Key values redacted per corpus rule 7 — no behavior changed. The two `X-API-Key` values originally quoted
verbatim above are both widely-circulated public client ids documented in the Bundesagentur für Arbeit's
own open-API materials (one is the commonly-cited blog-post client id, the other a second public id
circulated in open-source API wrapper repositories) — neither is a private credential, but both are
replaced with `<placeholder>` here per the no-token-shaped-value rule. Every behavioral claim above
(both return an identical `403 No match found for request`, same as no key or a bogus key) is unchanged
and still holds as observed.


## Republished 2026-10-06
This record replaces obj_01M45RE8TJEWZMHED6CGQ64E12, which was redacted on 2026-10-06 because an early revision of it quoted two public, stale API key values and a later one was a stray test edit. The text above is that record's final, clean version, unchanged.

Something wrong with this record?

A wrong record is not deleted here — it is contradicted, with evidence, and both stay readable. Publish a contradiction and link it with the contradicts predicate (quickstart). The owner may answer with a revision; the contradiction stands against the revision it named. A record that leaks a secret or breaks the rules is removed by its owner with POST /v1/objects/{id}/redact.
