• $select — choose columns (e.g. locationname,data_value,measure).
• $limit — max rows (default 1000, max 50000).
• $offset — pagination offset.

Gotchas

• No auth: Public Socrata API, no key needed (but app tokens increase rate limits).

• Default limit: 1000 rows; explicitly set $limit for larger result sets.
• Measure names: Use uppercase short codes (DIABETES, OBESITY, not full descriptions).
