  • extend_sessionAdd time to an active hourly parking session.No findings

    Why it is in this group

    • The description's first verb is "add": a word for a change.
    • The server marks it destructive (destructiveHint: true).
    Description, as the server wrote it
    Add time to an active hourly parking session. No API key needed: ask the driver for the phone code on their receipt or pass, the last 3 characters of their plate, and how many hours to add (0.5 to 8, in half-hour steps). The answer is the price, the new end time and a pay_url to the driver's session page: send the driver there to pay. Nothing is charged and the end time doesn't move until they pay. Any mismatch gets one answer, SESSION_NOT_FOUND. With an API key (sessions:write), session_id and session_code extend the session through the API.

  • quotePrice to park at a lot for a number of hours, at the lot's current rate (daily max applied).No findings

    Why it is in this group

    • Nothing in its name or description says what it does, so it is counted as a write.
    • The server marks it read-only (readOnlyHint: true), but an annotation never lowers a class.
    Description, as the server wrote it
    Price to park at a lot for a number of hours, at the lot's current rate (daily max applied). No API key needed. booking.mode says what comes next: reserve (call reserve to hold a space) or pay_at_qr_page (give the driver booking.pay_url, where they pay and park).

    Annotations the server declares

    • readOnlyHint: true
    • destructiveHint: false
    • openWorldHint: false
  • reserveHold space at a lot for the driver for a few minutes (POST /api/v1/reserve rules).No findings

    Why it is in this group

    • Nothing in its name or description says what it does, so it is counted as a write.
    Description, as the server wrote it
    Hold space at a lot for the driver for a few minutes (POST /api/v1/reserve rules). No API key needed. Ask the driver to confirm before calling it. Lots that take payment at their QR page place no hold: you get status pay_at_qr_page and a pay_url to give the driver. A hold is confirmed with POST /api/v1/reserve/confirm before it expires.

    Why it is in this group

    • The name "get_lot" says "get": a word for reading.
    Description, as the server wrote it

  • get_sessionCheck a parking session: lot, status, start and end times, rate, amount so far and extensions, with a link to the driver's session page.No findings

    Why it is in this group

    • The name "get_session" says "get": a word for reading.
    Description, as the server wrote it
    Check a parking session: lot, status, start and end times, rate, amount so far and extensions, with a link to the driver's session page. No API key needed: ask the driver for the 6-character phone code on their receipt or pass and the last 3 characters of their plate (session_id with session_code also works). Any mismatch gets one answer, SESSION_NOT_FOUND: ask the driver to check both. With an API key (sessions:read), session_id alone reads a session on your account.

    Annotations the server declares

    • readOnlyHint: true
    • destructiveHint: false
    • openWorldHint: false
  • search_lotsFind Park Graph parking lots near a place, nearest first, with spaces left and the current rate.No findings

    Why it is in this group

    • The name "search_lots" says "search": a word for reading.
    Description, as the server wrote it
    Find Park Graph parking lots near a place, nearest first, with spaces left and the current rate. No API key needed. Ask the driver where they're going and work out its latitude and longitude first. Each lot's id is what quote, get_lot and reserve take. The top-level summary is a one-line answer you can quote. An empty list means Park Graph has no lots near that point: say so, and never make up lots.

    • readOnlyHint: true

This is not a safety rating, and no finding is not a safety guarantee. The groups and findings come from fixed checks of the tool definitions the server returned on the date shown, not from its code or what it does when called. How the checks work.
