Steps
Register at worldtides.info to get an API key
Call the v3 endpoint (https://www.worldtides.info/api/v3) with lat/lon and the data types needed (heights, extremes, datums, stations)
Request the nearest station list if you need to identify the physical gauge underlying the prediction
Combine multiple data types in one call where possible to economize on credits
Parse the UTF-8 JSON response and convert timestamps to the marina's local timezone
Known gotchas
Additional data types or longer date ranges in one request can raise the credit cost above the base 1-credit request - check pricing before requesting broad ranges
Coverage claims 8,000+ locations, but accuracy near river mouths/estuaries can be lower than dedicated national tide-gauge networks
API keys reset from account settings if ever exposed - rotate rather than reuse a leaked key
