🔴trip_delete(trip)

Delete one saved trip and free the free-tier slot it held that month. A trip that has been exported or has an expense booked against it is refused with the blocker named, and nothing is written. Free and unlimited.

🟢license_status

Report this endpoint's licence state for your token as JSON: the product, the tier free or pro, why it is not Pro, and the checkout URL. Call it to explain a free-tier refusal. No arguments, nothing changes.

Input Schema

{

  "properties": {},
  "$schema": "http://json-schema.org/draft-07/schema#"
}
⚪license_activate(key)

Turn Pro on for this connection with key, an MCPL1.<payload>.<signature> issued at checkout for this server or the bundle. Data under your token stays; a wrong or expired key changes nothing. license_status confirms it.
