German federal parliament: Vorgänge (procedures), Drucksachen, Plenarprotokolle, Personen, Aktivitäten. Key required on every data path; the spec is public.\n\n## The published key\n\n`GET https://search.dip.bundestag.de/api/v1/openapi.yaml` → 200 `application/yaml`, 82,117 bytes, OpenAPI 3.0.1 \"Deutscher Bundestag - DIP\" v1.5. Its `components.securitySchemes` declares two carriers — `ApiKeyHeader` (`in: header`, `name: Authorization`) and `ApiKeyQuery` (`in: query`, `name: apikey`) — and the header scheme's `description` reads `Beispiel: *ApiKey <42-character key>*`. **That example key is live.** Sent as `?apikey=<it>` or as `Authorization: ApiKey <it>`, `GET /vorgang?f.datum.start=2026-09-01` returned **200**, `numFound: 1193`, 100 documents, 85,954 bytes — identical bodies for both carriers. The key is the service's own published example (the help page `https://dip.bundestag.de/über-dip/hilfe/api` is a JS shell, 2,375 bytes, so the YAML is the machine-readable place to read it); it is not reproduced here — read it from the spec at run time, and expect it to rotate.\n\n## Refusal shape — missing and wrong keys are indistinguishable\n\n| Request | HTTP | Body |\n|---|---|---|\n| `GET /vorgang?f.datum.start=2026-09-01` (no key) | **401** | `{\"code\":401,\"message\":\"An API key is required to access this service.

There is no `next` link and no `hasMore`; the terminator is *cursor(n+1) == cursor(n)*, not an empty `documents[]`.\n- `f.id`, `f.wahlperiode`, `f.person` are repeatable (OR-search). `format=xml` → 200 `application/xml`, 136,464 bytes for the same page (vs 85,954 JSON).\n\n## Date grammar and not-found shapes — all JSON, all `{\"code\":N,\"message\":…}`\n\n| Request | HTTP | Body |\n|---|---|---|\n| `f.datum.start=01.09.2026` (German order) | **400** | `{\"code\":400,\"message\":\"Invalid date: 01.09.2026\"}` |\n| `f.datum.start=2026-13-01` | 400 | `{\"code\":400,\"message\":\"Invalid date: 2026-13-01\"}` |\n| `GET /vorgang/999999999` | 404 | `{\"code\":404,\"message\":\"ID not found: 999999999\"}` |\n| `GET /vorgang/abc` | **404** (not 400) | `{\"code\":404,\"message\":\"ID not found: abc\"}` |\n| `GET /nonexistent` | 404 | `{\"code\":404,\"message\":\"Invalid context ID: nonexistent\"}` |\n\n`cache-control: no-transform, max-age=300` on data responses; no rate-limit headers seen.
