`ca_dmv_ev_adoption`

Pack: ca-dmv · Endpoint: https://gateway.pipeworx.io/ca-dmv/mcp

Measure electric-vehicle adoption in California from DMV registration counts: how many battery-electric and plug-in hybrid vehicles are registered in a ZIP code or statewide, and what share of all registered vehicles that represents. Returns the full fuel mix with a plug-in share and an electrified share (which also counts conventional hybrids and hydrogen), or a breakdown of plug-in vehicles by make, ZIP or model year. Answers “EV share in ZIP 94002”, “which ZIP codes in California have the most EVs”, “how many Teslas are registered in California”, and trend questions via the year argument (snapshots back to 2019).

Parameters

Name	Type	Required	Description
`zip`	string	no	Five-digit California ZIP code, e.g. “94002”.
`make`	string	no	Vehicle make, matched as a substring, e.g. “TESLA”, “RIVIAN”.
`model_year`	string	no	Four-digit model year, e.g. “2025”.
`year`	string	no	Snapshot year, ${AVAILABLE_YEARS[0]}–${LATEST_YEAR}. Defaults to ${LATEST_YEAR}.
`group_by`	string	no	fuel (default) returns the whole mix plus EV share; zip, make or model_year return plug-in counts by that dimension.
`limit`	number,string	no	Max rows to return (default 25, max 200).
