# Proklep > Proklep is a Czech web application for searching companies, sole traders and people in public registers and exploring their business relationships. Operated by Chai Ventures s.r.o. Search by company name, person name, Czech company identifier (IČO), Czech tax identifier (DIČ) or a published bank account. Public profiles may include register data, business roles, related subjects, filings and financial results, depending on source coverage. The web search accepts a complete 17-character VIN and can show available vehicle records and disclosed business relationships from the Czech road vehicle register. Private individuals' identities are not disclosed in the open vehicle data. A missing match does not establish that a vehicle does not exist or that its history is clear. The photo button in the web search reads VIN, IČO or Czech DIČ from a selected image and fills the search field. When several identifiers are found, the user chooses one. Recognition can fail; the user can retry with a clearer image or enter the identifier manually. VIN lookup and photo search are available only in the web application. The REST API and MCP tools return vehicle records only as part of a subject's fleet. ## Product and access - [About and contact](https://proklep.cz/o-nas): Product scope, source limitations and operator contact. - [FAQ](https://proklep.cz/faq): Search, source coverage, account access and subject unlocks. - [Plans](https://proklep.cz/#start-plan): Current prices and usage limits.
