Tools: find_stations plan_paddle tide_times currents best_low_tides marine_forecast marine_warnings coast_map_pass start_pass_purchase pass_status water_temperature
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. params: lat*, lng*, kind, limit |
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. params: lat*, lng*, from |
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. params: station, lat, lng, days, from |
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. params: station, lat, lng, days, from |
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. params: station, lat, lng, days |
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. params: lat*, lng* |
marine_warnings | Marine warnings (gale, storm, small craft…) in effect for the marine forecast area at a point. params: lat*, lng* |
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. params: none |
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. params: none |
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. params: reference* |
water_temperature | Water temperature from the nearest buoy within 40 km, otherwise satellite sea surface temperature. params: lat*, lng* |
Entries describe changes in tool definitions. They are not statements about a server, its quality or its author. The grade measures how the tool definitions fit model providers (token cost, schema compatibility, confusable names) as scored by the ToolFit engine at the time of the listing. JSON: append .json.
