@pipeworx/wi-dmv

Wisconsin DMV (WisDOT) customer service centers, with the services each individual counter actually performs. Keyless.

Why Wisconsin gets its own pack

This came out of splitting a single multiplexed us-dmv tool into one pack per state agency. Wisconsin's grain is a per-station capability matrix — does this counter issue commercial plates, give the written knowledge test in a language other than English, take cash — which has nothing in common with California's ZIP-level registration snapshot or New York's record-level file. A union schema across states leaves most arguments ignored on every call, so Wisconsin's arguments are Wisconsin's.

Tools

Tool	What it returns
wi_dmv_offices	Address, county, per-day hours, coordinates, wheelchair access, accepted payment methods, and the 13 service capabilities each center publishes

Filters: city, county, zip (prefix match), name, service (matches both the service labels and the payment methods), limit.

The distinctive field

DRV_KNLG_TEST_VAR_LANG_FL — surfaced as the service label "knowledge test in multiple languages" — records, per counter, whether the written knowledge test is offered in languages beyond English. No other state DMV layer publishes this. It is what makes "which Wisconsin DMV gives the written test in Spanish" answerable at all: 79 of the 88 centers do.

Auth

None. dotmaps.wi.gov is a public WisDOT ArcGIS host.

Gotchas worth knowing

• WisDOT's ArcGIS host is intermittently slow. It overran a 12s budget on a production call and answered in ~1s on the retry; during this pack's smoke test one call took 15.3s (a stall plus a successful retry) while the identical call either side of it took 93ms. Queries run on the shared helper's 15s budget with one retry, and a genuine stall returns { error, hint } telling the caller to retry rather than an empty office list that reads as "Wisconsin has no DMV offices".
• The statewide count moves. WisDOT opens and closes rural counters — the layer held 92 centers in mid-2026 and 88 as of 2026-07-30. Nothing in this pack hardcodes the number; responses carry statewide_office_count from the live layer, and the not-found hint quotes the live figure.
• LAT/LON are real attribute columns on this layer, unusually for a state ArcGIS service, so no outSR=4326 geometry round-trip is needed.
• There are no per-station phone numbers. WisDOT routes every center through one statewide number, so phone is null by design rather than by omission.
• Hours list open days only. STN_HRS_* carries the literal CLOSED for the rest; a day absent from hours is a closed day. Many rural counters open one or two days a week.
• services_excluded is the interesting negative space. WisDOT's STN_EXLD_PRDT_DSPL is free text naming transactions that specific center sends elsewhere (salvage titles, personalised plates, commercial over 10,000 lb) — it is returned verbatim, whitespace-collapsed.
• service matches payment methods too, so service: "cash" is a valid filter alongside service: "commercial vehicle plates".

Using with ask_pipeworx

Instead of calling tools directly, you can ask questions in plain English:

ask_pipeworx({ question: "your question about Wisconsin DMV data" })

The gateway picks the right tool and fills the arguments automatically.
