FAQ
What people ask us most.
Credits, model accuracy, data, and API access.
The RV Model is a valuation engine for used vehicles (electric, hybrid, petrol and diesel) across 14 European markets. Enter a car's details (make, model, trim, year, mileage) and it returns the current market value plus a 6-year projection, with a P10–P90 band. The projection is a depreciation scenario: it has not yet been validated against forward measurements.
Credits are the platform's unit of use. Every action consumes a fixed amount:
- Individual valuation: 1 credit
- Per-vehicle forecast: 1 credit
- Portfolio reforecast: 1 credit per vehicle
The free account includes 5 welcome credits to try the engine. You can top up your balance with credit packs whenever you need to.
No. Unused credits never expire as long as your account stays active.
The model is our own, one per country, and the models are updated and measured continuously. We measure the accuracy of the value we serve in every cycle; the results are available on request for professional clients. Every valuation ships with its P10–P90 band so you can see the likely range of values.
Our own market data, aggregated and validated, from the 14 countries in service, plus a reference new-vehicle price per trim and year. We only work with aggregates, never with personal data.
Yes. The REST API serves valuations across all 14 countries, with full traceability of the adjustments applied. If you have a B2B use case (dealership, insurer, leasing company, marketplace), get in touch for your API key and volume terms.
Yes. Signing up and verifying your email gives you 5 welcome credits to try real valuations. No credit card required.
No. ARST Data has no subscription plans: you create a free account with 5 welcome credits and buy credit packs as you need them. Unused credits never expire as long as your account stays active.
No. The model covers electric, hybrid, plug-in hybrid, petrol and diesel vehicles across all 14 markets. Electric vehicles in Spain were the starting point; today coverage spans the entire used-vehicle market in every country where we operate.
Market data is updated frequently across all 14 markets, and valuation models are updated and measured continuously.
Every valuation returns three prices: P10 (conservative), P50 (market value) and P90 (optimistic). The P10–P90 band is nominally 80%; in the October 2026 measurement it covered less than that 80%, so treat it as guidance. The band narrows when there are many comparable vehicles and widens in segments with low liquidity.
The RV Model covers 14 European markets: Spain, Germany, France, Italy, the United Kingdom, the Netherlands, Austria, Belgium, Luxembourg (BE model), Portugal, Poland, Sweden, Norway and Finland.
It is not real-time. Market data and models are updated periodically, so a valuation reflects the recent market, not this very moment. If your use case needs something else, tell us about it.
Yes. For large portfolios or recurring bulk reforecasts, get in touch for a custom B2B agreement with API access and negotiated volume pricing. Write to us at info@arstdata.com.
