# Allo Cars

Free car tools and open data for drivers in Germany, by Spiking Labs (part of allo.land). Tool inputs live in the URL, so a filled-in link reproduces a result. Machine-readable tool list: https://cars.allo.land/tools.json

## Tools
- [EV charging cost vs petrol and diesel](https://cars.allo.land/ev-cost/): cost per 100 km at any price per kWh for your EV, and the break-even electricity price against popular German petrol and diesel cars. Parameters: https://cars.allo.land/ev-cost/spec.json
- [Charging price archive](https://cars.allo.land/charging-prices/): ad-hoc charging prices in Germany over time.

## Data
- [Ad-hoc EV charging prices, latest](https://cars.allo.land/data/charging-prices/latest.json): median, p10, p90 of the base energy price (EUR/kWh incl. VAT) over all published ad-hoc tariffs, overall and per data source.
- [Daily price history](https://cars.allo.land/data/charging-prices/daily.csv): one row per day and source (date, source, tariffs, median, p10, p90, min, max). Collection started 2026-11-06.

Data from the Open ChargePoint Database (MobiData BW), which merges AFIR feeds published on Mobilithek. Licences per source are in sources.json.

## Regions
Data is arranged by region: https://cars.allo.land/data/<dataset>/<region>/<file>, with lowercase ISO codes (de for Germany). The list of regions, and which datasets each has, is at https://cars.allo.land/regions.json. Germany is the only region so far; the short URLs above without a region are Germany. Add ?country=<code> to any page link to pick the country.

## Pages
Every page is also in German under /de/ (for example https://cars.allo.land/de/ev-cost/), with the same link parameters.
