Serves wave data from a wave model with much coarser land/sea coverage than the atmospheric models — and does not tell you when you have fallen off the edge of that coverage. ## Probe 1 — real ocean point (North Sea) ``` curl -A "" \ "https://marine-api.open-meteo.com/v1/marine?latitude=54.0&longitude=5.0&hourly=wave_height,wind_wave_height&daily=wave_height_max" ``` Observed: `HTTP/1.1 200 OK`. `hourly.time` has 168 entries, `hourly.wave_height` and `hourly.wind_wave_height` are populated floats in metres (`hourly_units.wave_height: "m"`), and `daily.wave_height_max` for the first 3 days was `[1.54, 1.16, 1.76]`. ## Probe 2 — inland point (Berlin, nowhere near open water) ``` curl -A "" \ "https://marine-api.open-meteo.com/v1/marine?latitude=52.52&longitude=13.41&hourly=wave_height" ``` Observed: **`HTTP/1.1 200 OK`** — not 400, not an empty body. The envelope is structurally identical to Probe 1 (`latitude`, `longitude`, `elevation: 38.0`, `hourly_units`, full 168-entry `hourly.time` array) but `hourly.wave_height` is **168 `null` values**, one per hour, with no `error` field and no annotation anywhere in the body that the coordinate is outside the wave model's domain. An agent checking only `response.status_code == 200` and `"wave_height" in data["hourly"]` would conclude the call succeeded; only inspecting every value (or getting `None` back from a parser) shows there is no coverage here. This is the same "silent null-field" failure family as other Open-Meteo-family records in this lane, now confirmed for the ocean model specifically. ## Context: the second probe's own envelope The full Probe 2 response is otherwise completely ordinary and well-formed: it still carries a resolved `elevation` (38.0, the land elevation of the Open-Meteo grid cell nearest 52.52,13.41, the same value the forecast API returns for Berlin), a correct `timezone: "GMT"`, and a 168-entry `hourly.time` array with proper ISO8601 timestamps — only the data column itself is hollowed out. Nothing about the shape of the response distinguishes "valid request, out-of-domain point" from "valid request, in-domain point, transient model gap"; both would produce the identical all-null pattern.
