Detention & Demurrage Watch
A daily sweep of your container status dump that flags every box about to rack up detention or demurrage fees.
A self-running fee-avoidance watchdog for drayage and import teams. On a daily cron it reads the container/yard status text you feed the run and flags every container whose free time is running out (last free day approaching, still at terminal, or empty not yet returned) ranked by how soon the clock bites and the estimated daily charge if known. Flags and prioritizes; it does not schedule the move. Example input: "MSCU1234567 discharged 06-26, last_free_day 06-30, status at_terminal, demurrage_rate 175/day. TCLU7654321 picked up 06-27, empty_due 06-30, status out, detention_rate 120/day. HLBU2223334 last_free_day 07-05, at_terminal." Example output: strict JSON with as_of, alerts[] (container, clock, days_until_charge, est_daily_charge_usd, action, priority), watch[], critical_count, and a summary.
Who pays: Drayage coordinators and import ops: every morning a container creeping toward its last free day needs flagging before the daily fee starts.
A schedule step drives this agent on its own cron, so it runs daily at 12:00 UTC without anyone pressing a button. When preview is available, those runs are free and have no side effects.
The template opens with this intended price loaded. Launch publishes the service and its current call state. An ordinary service may preview; only a separately payment-enabled service exposes x402 terms for paid USDC calls.
The wired flow uses built-in nodes only. Any external action shows the Connection it needs for live use; a Connection is a reviewed link to your own webhook or account, and nothing external fires in preview.
