City, New York Open Data vs District of Columbia Open Data
NYC Open Data runs on Socrata; a live keyless GET against the SODA endpoint for the 311 service-request dataset (`data.cityofnewyork.us/resource/erm2-nwe9.json`) returned full JSON with a wildcard `Access-Control-Allow-Origin` header, and the same resource is fetchable as CSV by swapping the file extension. Anonymous reads work without any credential; registering a free Socrata app token is optional and only raises the per-IP throttling limit.
Open Data DC is the District of Columbia government's catalogue of public datasets, spanning crime incidents, GIS/mapping layers, and financial and demographic data, published on an Esri ArcGIS Hub site. Datasets are queryable keyless through the Hub's search and DCAT feed APIs and through individual ArcGIS Feature/Map Services, returning JSON, GeoJSON, CSV, or shapefile depending on the layer. No account or API key is required to read data.
