Scarleicester
Connected-vehicle data platform

One API for every vehicle in your fleet.

Scarleicester unifies manufacturer feeds and telematics devices into a single normalised API. Ship fleet features in days, without building and maintaining a connector for every make on the road.

What you get

The vehicle data layer you'd rather not build yourself.

Every manufacturer speaks a different dialect. Scarleicester translates them all, keeps the connections healthy and hands you clean data.

Unified Vehicle API

Every make, model and device lands in one documented schema. Units, enums and timestamps are normalised, so your code never branches on the manufacturer.

Live telemetry streams

Location, odometer, fuel, state of charge and ignition events delivered by webhook or stream, typically within ten seconds of leaving the vehicle.

Maintenance signals

Fault codes arrive decoded, ranked by severity and paired with service-due forecasts based on real mileage and engine hours.

Consent built in

Hosted consent flows record who agreed to what and when. Collection stops automatically the moment a grant is revoked.

Sandbox fleet

Simulated vehicles drive realistic routes and throw realistic faults, so you can build and test before a single real car is connected.

One schema

Ask any vehicle the same question. Get the same answer shape.

A diesel van reporting through an OBD-II dongle and an electric hatchback on a manufacturer feed return the same fields, the same units and the same fault model.

  • Versioned REST API with typed SDKs
  • Signed webhooks with automatic retries
  • Per-signal source timestamps and freshness
  • Idempotent commands with full audit trail

How it works

From VIN to live data in four steps.

Explore the platform
  1. 01

    Connect

    Link vehicles by VIN through manufacturer programmes, or pair an OBD-II or CAN device for anything older.

  2. 02

    Normalise

    Raw payloads are cleaned, de-duplicated and mapped to one schema with source timestamps preserved.

  3. 03

    Stream

    Subscribe to the signals you need by webhook, stream or scheduled export to your warehouse.

  4. 04

    Act

    Trigger service bookings, route changes and alerts from rules that run on live vehicle state.

Use cases

Built for the teams who keep vehicles earning.

Whether you run the fleet or write the software that does, the same data powers very different products.

Rental & leasing

Automate check-in mileage and fuel readings, spot damage-related faults early and recover vehicles faster.

Last-mile delivery

Feed live positions and remaining range into dispatch so routes reflect what each van can actually do.

Workshop networks

Turn decoded fault codes and service forecasts into booked jobs before a breakdown takes the vehicle off the road.

EV fleet operations

Track state of charge, charging sessions and battery health across mixed electric and combustion fleets.

Security & compliance

Vehicle data is personal data. We treat it that way.

Location history can identify a driver as surely as a name. Access is scoped to consent, encrypted end to end and logged in full.

Read our security approach
  • TLS 1.3 in transit, AES-256 at rest
  • Consent-scoped access on every request
  • UK and EU data residency options
  • Full audit log of reads and commands
