Safety & Limits

• Read-only: All tools perform HTTP GET requests only — no data is written, modified, or deleted.
• No personal data: The APIs return open civic datasets (parking occupancy, weather readings, parliamentary proceedings). No personally identifiable information (PII) is processed or stored by this server.
• Rate limits: CKAN Solr search and ParkenDD are public APIs without documented rate limits; use rows and limit parameters conservatively. The server enforces a 30s timeout per request.
• Data freshness: Real-time tools (parking, weather, air quality) reflect the upstream source at query time. No caching is performed by this server.
• Terms of service: Data is subject to the ToS of each source — data.stadt-zuerich.ch, ParkenDD, gemeinderat-zuerich.ch. All City of Zurich data is published under CC0 (Open by Default since 2021).
• No guarantees: This server is a community project, not affiliated with the City of Zurich or any of the API providers. Availability depends on upstream APIs.
