What ONE AUTO API LIMITED does
One Auto API Limited is a UK-based private limited company, headquartered in Leamington Spa, that operates a unified API platform aggregating automotive vehicle data from multiple upstream providers. Founded in 2022, the company targets software developers and automotive businesses that would otherwise need to integrate with several separate vehicle data APIs, each with its own schema and commercial terms. Its documented coverage spans the UK, Europe, and a broad set of international markets (Ireland, USA, Australia, New Zealand, Japan, India, China, Korea, Turkey, South Africa).
The core technology is a proprietary Common Data Dictionary that maps 1,100+ parameters across 15+ data providers, including tier-1 sources such as Auto Trader, Experian, Solera CAP HPI, EV Database, EVOX Images, Marketcheck, Brego, and Solifi. The platform exposes 100+ API methods through a REST interface, supported by SDKs in 30+ programming languages, a Swagger documentation site, a Postman collection, and a free sandbox environment. Beyond the developer-facing API, the company operates two packaged products: VRM 360 (a vehicle appraisal and history-check web application launched in beta in September 2023 and fully in October 2023) and Report Builder (a bulk data extraction tool launched in January 2024).
The business model combines usage-based API pricing with monthly subscription tiers (PAYG with a £30 deposit, Business at £25/month, Enterprise at £100/month) and bespoke quote-based pricing for complex enterprise requirements, plus Implementation Consultancy and Bespoke API Development services. The go-to-market motion is dual: self-serve product-led growth for developers and SMBs through free signup and documentation, combined with enterprise field sales for larger accounts. Stated customer segments include franchised and independent dealers, fleet operators, motor finance providers, motor insurers, software developers, auction and remarketing businesses, and aftermarket parts suppliers; three enterprise customers are publicly named (Loyalty Logistix, Exchange My Car, Bluesky Interactive). Headcount is 1-10 employees and no funding rounds are disclosed, consistent with a bootstrapped, early-traction company.
