+# QRZ.com XML API — what a free account returns, and what a subscription adds
+
+Captured 2026-08-02 on F4BPO's two accounts, same callsign looked up twice
+within a minute. Kept because the difference is the answer to a question that
+comes back regularly: *"someone told me their logger gets the 6-character
+locator from QRZ without paying"*. It does not.
+
+## Free account — `SubExp: non-subscriber`
+
+```xml

+## Consequences
+
+- **A free QRZ account can never fill the locator, the coordinates, the zones
+  or the e-mail.** If someone reports a logger doing it on a free account, they
+  are either using HamQTH (free, returns a 6-character `grid`) or they hold an
+  XML subscription without realising it — the QRZ.com account and the "XML
+  Logbook Data" subscription are sold separately. `SubExp` in the session block
+  settles it in one request.
+- **Profile edits take a few minutes to reach the XML feed.** Changing the grid
+  on the website and looking the callsign up immediately returns the OLD value,
+  which looks exactly like a stale cache. Re-test after a few minutes before
+  suspecting the logger. (This cost an hour on 2026-08-02.)
+
+## Fields OpsLog does not use yet
+
+`qrz.go` maps call, name, addr1/2, zip, state, county, country, grid, lat, lon,
+dxcc, cqzone, ituzone, cont, email, qslmgr and image. Left on the table:
+
+- **`geoloc`** — `user` when the operator entered the position by hand, versus a
+  geocoded value derived from the postal address. This is a direct statement of
+  how much the coordinates and the locator can be trusted, and it is exactly
+  the question the grid-precision rule in App.tsx tries to answer by comparing
+  string lengths. Worth wiring if the locator ever misbehaves again.
+- **`eqsl` / `mqsl` / `lotw`** — the station's QSL preferences as flags, more
+  reliable than parsing the free-text `qslmgr`.
+- `nickname` / `name_fmt`, `class`, `moddate`, `bio`.
