**Service:** Argovis (University of Colorado), a value-added REST API over the Argo float
network (indexed/searchable, unlike the GDAC's flat files above).

**Probe 1 — bare root:**
```
curl "https://argovis-api.colorado.edu/"
```
HTTP 404, `{"message":"not found","errors":[{"path":"/","message":"not found"}]}` — a
real JSON router 404, not a gateway/auth wall.

**Probe 2 — the documented `/argo` profile-search endpoint, no `Authorization` header, no
API key query param, one-day window:**
```
curl "https://argovis-api.colorado.edu/argo?startDate=2026-09-01T00:00:00Z&endDate=2026-09-02T00:00:00Z"
```
HTTP **200** — a JSON array of real profile documents starting immediately with
`[` then objects like `{"_id":"4903891_049","geolocation":{"type":"Point","coordinates":
[-111.5898,-6.7035]},"basin":2,"timestamp":"2026-09-01T23:55:48.002Z",...,"source":
[{"source":["argo_core"],"url":"ftp://ftp.ifremer.fr/ifremer/argo/dac/aoml/4903891/profiles/R4903891_049.nc",...}],"cycle_number":49,...}`.

No `401`, no `403`, no truncation notice — this lane's own briefing cluster text assumed
"Argovis API refusal/key" going in; the live behavior today is the opposite: fully open
reads with no registration step for this query shape. (Per campaign rule 13: the brief is a
hypothesis, the record is the observation.)

How observed: 2026-10-05T09:06:55Z–09:07:00Z, two live `curl` GETs, `-m 60
--max-filesize 20000000`, no key sent.


**Probe 3 — how many profiles came back, and was anything truncated? (added on revision):**
Counting the returned JSON array: **468 profile documents** for the single one-day window
(`2026-09-01T00:00:00Z`–`2026-09-02T00:00:00Z`) queried above, with no `truncated` flag,
no `next`/cursor field, and no documented page-size default observed in the response
envelope at all — the array IS the full response, a bare top-level JSON list rather than
an `{"items":[...], "next":...}` wrapper. Timestamps in the returned documents range across
the full requested window (`2026-09-01T23:55:48.002Z` down to `2026-09-01T00:00:29.000Z`),
consistent with no silent truncation for this particular one-day, global query size.
