How this service works
Estimates great-circle port distance and sailing time from supplied port coordinates and speed. Missing facts are returned as null and named in unavailable_fields where applicable. Derived values disclose their method; source-backed values disclose source, time window and age.
Output
Returns the estimated great-circle distance in nautical miles between the two port coordinates, the computed sailing time based on the supplied speed and detour factor, method disclosures explaining how derived values were calculated, and an unavailable_fields array listing any facts that could not be returned as null.
Example use cases
Freight quote transit time estimation
“I need to estimate how long a cargo ship doing 12 knots would take to sail from Hamburg (53.5753° N, 9.8689° E) to New York (40.6840° N, 74.0479° W) — can you calculate the great-circle distance and sailing time, using a detour factor of 1.15?”
Shipping route comparison for logistics planning
“Compare the sailing distances and transit times for a vessel at 15 knots between Singapore (1.2897° N, 103.8501° E) and Los Angeles (33.7395° N, 118.2703° W) versus Singapore to Sydney (33.8688° S, 151.2093° E) — use a detour factor of 1.1 for both.”
Automated freight booking ETA calculation
“For a ship traveling at 10 knots, what's the estimated sailing time from Durban (29.8587° S, 31.0218° E) to Mumbai (18.9388° N, 72.8354° E)? Use a detour factor of 1.2 and tell me the great-circle distance too.”
Technical details
Endpoint
POSThttps://fracht.halowerk.com/v1/port-pairWhen to prefer
Choose this endpoint when you need a fast, lightweight great-circle distance and sailing time estimate between two known port coordinate pairs for freight planning, ETA computation, or route comparison — especially when you already have lat/lon values and a vessel speed. It is ideal for automated logistics pipelines that need transparent method disclosures. Use alternatives when you need actual navigational routing that accounts for land avoidance, canals, or real ocean lane data.
Side effects
- Invalid or out-of-range coordinates (lat > 90 or lon > 180) result in validation errors
- Speed outside allowed range (0.1–100 knots) returns a schema validation error
- Detour factor outside 1–5 range is rejected
- Both origin and destination are required; missing either results in an error
- Some derived fields may return null with the field name listed in unavailable_fields if computation is not possible
