# Entenhausen Fictional German municipal demo, not a government or Disney service. - Website: https://entenhausen.stage.dev/ - Service contracts: https://entenhausen.stage.dev/v1/services - OpenAPI 3.1: https://entenhausen.stage.dev/openapi.json - Developer guide: https://entenhausen.stage.dev/api-entdecken - Sources and fictional additions: https://entenhausen.stage.dev/quellen - Guided chat: https://entenhausen.citychat.stage.dev/ Use the public catalogue, not guessed fields. All transaction inputs are fixed synthetic choices. Create an isolated 24-hour session, prepare a draft, show its returned review, then obtain explicit confirmation before submitting its version. Preserve the idempotency key and exact JSON on retries. Never put the bearer capability in prompts, URLs or logs. A received request is not an approval. No payments, genuine identity data, uploads, external messages or real bookings are supported. Town facts come from the sources page. The Bavarian administrative setting, fees in Talers, municipal forms, timelines and demo profile addresses other than Donald's cited Blumenstraße 13 are invented. Do not present them as comic canon or German law.
