geo.qa

A managed deployment of the open emem protocol. Ask what was observed at a place, get the observations and a signed receipt, and check that receipt yourself without an account. Satellite facts are signed by emem.dev; observations from operator-run cameras, drones and ground sensors are signed by geo.qa. Both keys are published.

Skills

• Read a place: what is there now, and the proof
  Read a whole place at once. Returns what geo.qa's cameras see there right now, how that compares with three hours ago, and the signed evidence under every number: the sha256 of the clip each count came from, the detector's function id, and a receipt cid that verifies with no key. Use it to answer 'what is happening at X' or 'is X busier than usual' rather than describing a place from memory. Places with no camera get the distance to the nearest one, not a number.

• Check a receipt this service did not have to issue
  Re-check any geo.qa or emem receipt and get back one uniform verdict: valid true, false, or null. null means nothing was checked -- it is never dressed up as a pass. A geoqa receipt is verified locally by recomputing its canonical preimage against the published key, so it stands up with this service offline; an emem receipt is checked by emem, whose key is also published. No credential, now or ever.

• Detect objects in an image
  Open-vocabulary detection on one image. Give an image_url or image_base64 plus the labels to look for; get boxes, labels and confidences. Needs no credential, bounded per IP.

• Describe a scene
  Vision-language description of one frame, optionally answering a question about it. Prose from a language model: it is returned unasserted and carries no signature. Metered.
