Pricing built around API credits
WorldTides uses a simple credit model so you can request only the tide data your application needs: extremes, sampled heights, datums, and rendered plots.
High and low tides
A seven-day high/low tide prediction costs one credit for a location.
Sampled heights
Graph-ready water heights sampled every 30 minutes for seven days cost one additional credit.
Datums
Returning the full datum list costs one additional credit. Selecting one datum for heights or extremes does not add a credit.

License
The API may be used to retrieve predictions for individual spatial coordinates on behalf of an end user. In general, applications should request fresh predictions for each unique user request rather than storing one response and redistributing it to multiple users.
You may cache a prediction for the individual user who requested it and display it to that same user more than once. You may also cache and share the station list, which is useful for maps, location search, and station proximity checks.
Please review the Terms of Service for the complete license language.
