Read the recorded sale or rental transactions of one development. Sale rows carry the month, block, masked unit, bedrooms, area in square feet, price and price per square foot. Rental rows carry the month, bedrooms, an area band, rent and rent per square foot. Every row keeps the display label and adds parsed numbers. The response also returns the table headers, pagination, and the overview with profitability and price statistics. Take the development_id from a /search item or from /autocomplete. District, area and street ids are not accepted. A development id that does not exist is a non-billable 404, and a page past the last one is an empty page that keeps the requested page number.
