DataSF (San Francisco open data) / Find datasets on data.sf.gov

Search the public dataset catalog of data.sf.gov (San Francisco) by keyword, category or tag. Each result has the dataset id (needed by the query and metadata routes), name, description, column names and types, update dates, owner agency, category, tags and page link. Examples on this portal: building permits (i98e-djp9), business locations (g8m3-pdis), 311 cases (vw6y-z8j6), police incidents (wg3w-h783). Up to 20 results per call (default 10), offset up to 1,000. Free: the Socrata SODA API on data.sf.gov needs no key. Anonymous calls share an IP rate limit, so a burst can answer 429 (rate_limited, $0).
