      summary: Run a public feed command and receive XML
      description: 'Executes one of the nine documented feed commands and returns XML. The `command` parameter selects the operation; the remaining query parameters are read only by the commands that use them (see each parameter''s description). Polling commands (`vehicleLocations`, `predictions`) should be called at most once every 10 seconds. Send `Accept-Encoding: gzip, deflate` to receive compressed responses (50-85% smaller).'

      summary: Run a public feed command and receive JSON
      description: The JSON rendering of the same feed. Accepts exactly the commands and parameters of `/publicXMLFeed`. Every value is serialised as a string (numbers and booleans included), and an element that occurs once is rendered as an object where a repeated element is rendered as an array, so clients must accept both shapes. Documented in the PDF only by reference; the `/publicJSONFeed` path itself was confirmed live on 2026-09-19.

This document was written by API Evangelist from that PDF and then checked command-by-command against the live host on 2026-09-19 (see x-evidence). Nothing here is asserted that the PDF does not document or the host did not answer.
