# TrustRails > A UK electronics product data layer: retailer feeds standardised, matched by GTIN barcode, and made readable by AI systems, both as structured web data and as a live API and MCP server. TrustRails takes the product feed a retailer already publishes and republishes it in a format AI assistants and answer engines can read directly. Structured pages carry schema.org Product, Offer, and GTIN data; a public API and MCP server let agents query prices and stock directly. ## Key pages - [Retailers](https://trustrails.app/retailers): what TrustRails does, how it works, and how to get a product feed connected. - [What is GEO](https://trustrails.app/geo): Generative Engine Optimization, explained. - [What is MCP](https://trustrails.app/mcp): Model Context Protocol, explained. - [Developers](https://trustrails.app/developers): API docs and quickstart for querying the catalogue directly. - [Live Explorer](https://trustrails.app/explorer): try real API queries against the live catalogue. ## Proof - [trustrails-compare.com](https://trustrails-compare.com): a live UK price-comparison site built entirely on this catalogue, real proof the data works, not a pitch deck. ## Optional - [Privacy](https://trustrails.app/privacy)
