Vehicle data API cost calculator

How vehicle data is usually priced

Most UK vehicle data is sold one of three ways. Per lookup means you pay for each request, usually from a prepaid balance, with the rate falling as you commit to more. A monthly subscription bundles an allowance into a fixed fee, which is cheaper per lookup if you use the allowance and wasted if you do not. An enterprise contract sets a rate against a committed annual volume, typically with a minimum spend and a term.

The headline rate is rarely the whole cost. What actually determines your bill is which of those three you are on, whether unused allowance rolls over, and: most of all: what counts as a chargeable request.

What counts as a chargeable lookup

This is where estimates and invoices diverge. A supplier that bills on every request charges you for registrations that do not exist, for typos, and for records with nothing in them. If a tenth of your traffic is bad input: normal for anything with a customer-facing registration field: a headline rate is a tenth cheaper than what you actually pay.

VehicleMatic charges only on a successful lookup. A request that finds no record costs nothing, so the rate in this calculator is the rate you pay. When you compare suppliers, ask specifically whether a no-match is billable, and whether a partial response counts as a success.

Working out your real volume

Three things tend to make the estimate wrong in practice:

• Repeat lookups on the same vehicle. A quote journey that re-checks a registration at each step multiplies your volume. Cache the response for the length of the session.
• Seasonality. Dealer and insurance volumes move with plate-change months, so March and September can run well above your average.
• Bundling. If you need several data points on the same vehicle, one combined call is usually cheaper than four separate ones: that is what the Full Vehicle Check is for.

Reading the result above

The figure is your monthly cost at pay-as-you-go rates, with the top-up tier chosen automatically from your spend. Larger top-ups move you down the ladder, so the per-lookup rate falls as volume rises without you having to negotiate anything. All figures exclude VAT. Nothing here needs a contract, and credits are bought when you want them rather than committed to in advance.

If the number matters to a decision, check it against the live pricing matrix, which is the authoritative source, and test the response shape in the sandbox before you integrate. Signing up gives you ten free lookups, which is enough to confirm the data is what you need.
