Tools as reported by the server

• find_stations
  Nearest tide stations (high/low times) and current stations (slack water, max flood/ebb) to a point, with distance and time zone. Coverage: Canada, the US, Norway, Ireland, the Netherlands, New Zealand, Australia (Queensland) and modelled tides elsewhere.
• plan_paddle
  One call that answers "what will the water be like at this spot?": the nearest tide station with 2 days of highs and lows, currents nearby, the next 24 h of wind, gusts and waves with the maxima, warnings in effect, water temperature and sunrise/sunset, with the important heads_up lines listed first
• tide_times
  High and low tides with heights, in the station's local time. Up to 7 days ahead free; longer ranges (up to 90 days) need the user's Coast Map Pass key.
• currents
  Slack water and maximum flood/ebb times and speeds at a current station, in local time. Up to 7 days free; longer with a Coast Map Pass key.
• best_low_tides
  The lowest daylight low tides over the next days (default 30, up to 90 with a pass key), marking the good ones for clamming, foraging and tide pools.
• marine_forecast
  Hourly wind and gusts (knots), direction, temperature, rain, fog and thunder risk for the next 48 hours, plus wave height and period, from Environment Canada (HRDPS/GDWPS), the US National Weather Service or MET Norway.
• marine_warnings
  Marine warnings (gale, storm, small craft…) in effect for the marine forecast area at a point.
• coast_map_pass
  What the Coast Map Pass adds over the free map (offline regions for trips with no signal; longer tide and current ranges for assistants), its prices (CA$5 a month or CA$55 a year), whether it is on sale yet, and the purchase or support links. Covers offline use, longer tide ranges and upgrading.
• start_pass_purchase
  Begin a Coast Map Pass purchase without leaving the conversation: returns checkout links (CA$5 a month or CA$55 a year, Stripe, no account) tagged with a purchase reference, or says the pass is not on sale yet. The user pays in their browser; the reference identifies that payment afterwards.
• pass_status
  Checks whether the payment for a purchase reference has completed. Returns pending (with a retry interval) or paid with the pass key, which is sent as "Authorization: Bearer <key>" from then on, plus a link that activates the pass in the user's own map.
• water_temperature
  Water temperature from the nearest buoy within 40 km, otherwise satellite sea surface temperature.
