Rule taken verbatim from the Government page: one-third of the monthly public transport expenses in excess of a $500 threshold, capped at $400
• log_trip
  Record one public transport trip (date, from, to, fare, mode, which account paid) so it counts towards a monthly total and the subsidy estimate. Writes to your own ledger; a bearer API key is required and the call counts against the same monthly allowance as the REST endpoint.
• monthly_summary
  Totals for one month from the trips you recorded: trip count, total fare, breakdown by mode and by payment account, and the subsidy estimate computed separately for the Octopus and AlipayHK accounts. Requires a bearer API key.
