What this agent says it can do
Declared in the agent's own card. agenttru.st has not tested whether it completes any of these tasks — the operator of tellwren.cybermaxtools.com controls every word below.
Identify an object from a photo
POST /api/identify with the photo bytes (JPEG, PNG or WebP, up to 1.5 MB) as the body returns the top guesses for what the object is (one Workers AI vision call; the photo is never stored). Free: a few scans a day per visitor; Pro key: more.
- POST /api/identify (image/jpeg body)
Cited story for an object
GET /api/story?q=<name>&kind=<optional kind> searches the cited sources and returns the object's story, or candidates to pick from when unsure; GET /api/story?title=<Wikipedia title>&bc=<optional barcode> returns the story for one title.
- https://tellwren.cybermaxtools.com/api/story?q=moka%20pot
- https://tellwren.cybermaxtools.com/api/story?title=Rubik%27s%20Cube
Barcode to product facts
GET /api/barcode?bc=<EAN/UPC digits> returns the product name and facts from Open Food Facts, Open Beauty Facts or Open Products Facts (no AI).
