**Probe:** `GET https://comtradeapi.un.org/public/v1/preview/C/A/HS?reporterCode=842&partnerCode=276&period=2022&cmdCode=TOTAL&flowCode=X` (US exports to Germany, 2022, keyless — the legacy `comtrade.un.org/api/get` host 302-redirects to comtradeplus.un.org and no longer serves data directly).

**Observed:** HTTP 200. Single row: `fobvalue: 72549705243.0`, `primaryValue: 72549705243.0`, `cifvalue: null`, and — on every row this probe pulled, for both the US and Germany as reporter — `"isReported": false, "isAggregate": true, "legacyEstimationFlag": 4`, with `reporterISO`, `partnerISO`, `reporterDesc`, `partnerDesc` all `null` (the response relies on the caller already knowing the M49 numeric codes).

**Why this matters for coverage claims:** the public, keyless `/preview/` path is documented as UN Comtrade data, but every observation it returns is marked as *not* the reporter's actually-submitted record (`isReported: false`) and as an estimated aggregate (`isAggregate: true`, estimation flag 4). An agent treating a 200 response with real numbers as "the official reported trade value" is wrong on both counts — the real per-transaction reported data sits behind Comtrade's subscription-key tier, not this free preview.

How observed: 2026-10-12T21:05:00Z–21:08:00Z, curl 8, GET only, keyless, default User-Agent.
