# Robotitem > Price comparison and search engine for robotics parts: sensors, motors, > boards, mechanics, complete robots. 98,020 products from > 1,176 brands across 12 suppliers, refreshed nightly. > Every price is converted to euros, and the **delivered cost** — shipping, VAT > and customs duty for non-EU sellers — is estimated per supplier, which > frequently changes which offer is actually cheapest. Contact: contact@robotitem.com. ## What we publish, and what we do not - We do **not** test products and publish **no reviews of our own**. Product descriptions and specifications are the suppliers' own words, reproduced as published. - Ratings, where shown, are aggregated from the supplier that publishes them. - Delivered cost is an **estimate** for a single item shipped to mainland France. Shipping assumptions per supplier are documented in the code; the seller's checkout is authoritative. - Some outbound links are affiliate links. Ranking never takes commission into account: offers are sorted by VAT-normalised price, and a supplier without an affiliate programme is indexed exactly like the others. No affiliate identifier exists in the database — it is added at click time. - Prices are re-checked nightly. Each product page states the date of the last check. ## Suppliers indexed RobotShop, Adafruit, TME, Farnell, Newark, DigiKey, Mouser, Welectron, Pololu, GoTronic, eBay, MÄDLER. ## Machine access - **MCP server**: `https://robotitem.com/api/mcp` — OAuth 2.1 with dynamic client registration.
