search_paint_colorsFind paint colours by name or code across all brands, e.g. "Hague Blue", "SW 7029", "agreeable gray", "grün". Matching ignores case and accents ("sniezny" finds "Śnieżny") and every word may be a prefix. Optionally restrict to one brand. Returns name, brand, code, hex, LRV (light reflectance, 0 = black, 100 = white), collection and the colour page url. To match a hex value or a colour from another brand, use find_equivalents instead.
get_paint_colorLook up one paint colour by brand and exact name or code, e.g. brand "Sherwin-Williams" + "SW 7029" or "Agreeable Gray"; brand "Farrow & Ball" + "Hague Blue" or "30". Case, spacing and accents are ignored. A brand sold in several markets (Dulux UK/PL, Sikkens NL/DE/IT, Beckers SE/PL) may return one match per market. If nothing matches exactly, returns close suggestions instead.
find_equivalentsFind the closest colours in OTHER brands to a given paint colour or hex value, e.g. "Behr equivalent of Farrow & Ball Hague Blue" or "which Benjamin Moore is closest to #D1CBC1". Give either brand + name_or_code, or hex. Distance is CIEDE2000 ΔE with a verdict: under 1 practically identical, under 2 very close, under 3.5 close, otherwise similar (nothing above ΔE 6 is returned). By default returns the single best match per brand, closest first; pass brands to restrict the search (with one brand you get several options from it). Always pass on the caveat that on-wall results depend on base, sheen and tinting.
list_brandsList the paint brands in the database with their number of colours and a brand page url. With country (ISO code like "DE", "PL", "US", "GB" or a name like "Germany"), returns the brands sold there in order of local relevance.
get_creditsPaid tools only. Show the Muro credit balance and plan of the connected account. Painting costs 1 credit per colour in Standard, 2 in HD and 3 in Ultra.
visualize_roomPaid (Muro credits, needs a Muro API key). Repaint the walls in a photo of a room, facade or roof in 1 to 12 colours at once and return one image per colour. Give the photo as image_url (a public link) or image_base64. Give each colour as brand + name_or_code from the catalogue (e.g. "Farrow & Ball" + "Hague Blue") or as hex. Without a photo it paints Muro’s sample room (or facade, roof). Every colour comes with a shopping list: the closest real paints from several brands with ΔE and a verdict; pass country to put brands sold there first. RAL works as brand "RAL" + "9005" or just "RAL 9005". Waits up to about 45 seconds; if some colours are still being painted, it returns a job_id for get_visualization. Tell the user the cost before calling: 1 credit per colour in standard quality.
get_visualizationPaid tools. Fetch the colours of a visualize_room job that were not ready yet, by job_id and project_id. Waits up to about 25 seconds. Costs nothing extra.
relight_roomPaid (1 credit). Relight a finished interior visualization as day, evening or night, with lamps on or off, keeping the wall colour. Needs project_id and the color_key returned by visualize_room.
