Measured tools (11)

• find_stations read-only

  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.

  Parameters:

  • lat (required) — number — Latitude in decimal degrees (WGS84).
  • lng (required) — number — Longitude in decimal degrees (WGS84), negative west of Greenwich.
  • kind — string
  • limit — integer

  Hints: read-only yes · destructive not declared · idempotent not declared · open-world yes

• plan_paddle read-only

  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.

  Parameters:

  • lat (required) — number — Latitude in decimal degrees (WGS84).
  • lng (required) — number — Longitude in decimal degrees (WGS84), negative west of Greenwich.
  • from — string — First day as YYYY-MM-DD in the station's time zone (default today). Free keys reach 7 days ahead of today.

  Hints: read-only yes · destructive not declared · idempotent not declared · open-world yes

• tide_times read-only

  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.

  Parameters:

  • lat — number — Latitude in decimal degrees (WGS84).
  • lng — number — Longitude in decimal degrees (WGS84), negative west of Greenwich.
  • days — integer — Days to cover, starting today at the station (default 2). Up to 7 free; up to 90 with a Coast Map Pass key.
  • from — string — First day as YYYY-MM-DD in the station's time zone (default today). Free keys reach 7 days ahead of today.
  • station — string — Station code from find_stations (e.g. "07795" for Victoria Harbour, "9447130" for Seattle). Give this or lat/lng.

  Hints: read-only yes · destructive not declared · idempotent not declared · open-world yes

• currents read-only

  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.

  Parameters:

  • lat — number — Latitude in decimal degrees (WGS84).
  • lng — number — Longitude in decimal degrees (WGS84), negative west of Greenwich.
  • days — integer — Days to cover, starting today at the station (default 2). Up to 7 free; up to 90 with a Coast Map Pass key.
  • from — string — First day as YYYY-MM-DD in the station's time zone (default today). Free keys reach 7 days ahead of today.
  • station — string — Station code from find_stations (e.g. "07795" for Victoria Harbour, "9447130" for Seattle). Give this or lat/lng.

  Hints: read-only yes · destructive not declared · idempotent not declared · open-world yes

• best_low_tides read-only

  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.

  Parameters:

  • lat — number — Latitude in decimal degrees (WGS84).
  • lng — number — Longitude in decimal degrees (WGS84), negative west of Greenwich.
  • days — integer
  • station — string — Station code from find_stations (e.g. "07795" for Victoria Harbour, "9447130" for Seattle). Give this or lat/lng.

  Hints: read-only yes · destructive not declared · idempotent not declared · open-world yes

• marine_forecast read-only

  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.

  Parameters:

  • lat (required) — number — Latitude in decimal degrees (WGS84).
  • lng (required) — number — Longitude in decimal degrees (WGS84), negative west of Greenwich.

  Hints: read-only yes · destructive not declared · idempotent not declared · open-world yes

• marine_warnings read-only

  Marine warnings (gale, storm, small craft…) in effect for the marine forecast area at a point.

  Parameters:

  • lat (required) — number — Latitude in decimal degrees (WGS84).
  • lng (required) — number — Longitude in decimal degrees (WGS84), negative west of Greenwich.

  Hints: read-only yes · destructive not declared · idempotent not declared · open-world yes

• coast_map_pass read-only

  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.

  Hints: read-only yes · destructive not declared · idempotent not declared · open-world yes

• start_pass_purchase read-only

  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.

  Hints: read-only yes · destructive not declared · idempotent not declared · open-world yes

• 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.

  Parameters:

  • reference (required) — string — The reference from start_pass_purchase (ag_…).

  Hints: read-only no · destructive no · idempotent yes · open-world yes

• water_temperature read-only

  Water temperature from the nearest buoy within 40 km, otherwise satellite sea surface temperature.

  Parameters:

  • lat (required) — number — Latitude in decimal degrees (WGS84).
  • lng (required) — number — Longitude in decimal degrees (WGS84), negative west of Greenwich.
