Sizely for AI assistants and developers

Sizely finds ready-made furniture from online shops that fits a particular niche or free wall. It searches by centimetres, not by category. AI assistants such as ChatGPT, Gemini or Claude, and your own tools, can search Sizely directly, without an account or API key. The shops and their product texts are German; parameter names and values are German too.

How to ask your assistant

Name Sizely and your measurements, for example:

Optional, the default is all furniture. Only set it when someone explicitly wants a certain kind of furniture, and do not ask for one: often a different kind fits.

One or more: weiss (White), schwarz (Black), grau (Grey), beige (Beige), holz-hell (Light wood), holz-dunkel (Dark wood), rot (Red), rosa (Pink), gelb (Yellow), gruen (Green), blau (Blue). Sizely detects the colour from the product image.

Response

Matches are in results, closest fit first, each with title, brand, shop, width, depth and height in cm, price in euros, detected colours, image, the product page on Sizely (url) and the buy link (buy_url). dimensions_confirmed_by_users counts how often visitors confirmed the dimensions.

Rules

• Please link buy_url for buying. It leads to the shop via Sizely.
• Prices and availability come from the shops, as of the last nightly import.
• Up to 120 requests per hour and IP address. Responses may be cached for 10 minutes.
