Satellites see heat. Sensors see position. Neither sees a queue at a fuel station, a substation still burning at hour thirty, or a port that quietly reopened. Witness delivers what only a person standing there can record, in a schema you can query.
Geotagged, timestamped, categorized events as JSON. Filter by bounding box, category, time window, and confidence.
Every event carries a confidence score and the evidence behind it, so you set your own threshold rather than inheriting ours.
Every reporter-originated event carries a capture record you can defend downstream.
Scoped keys, quotas, and full request logging.

}Machines cannot scrape what only a person standing there can record.
Aggregated feeds rent their data layer from platforms they do not control, which is why they cannot tell you where a file came from or vouch for what it shows. Witness owns the point of capture. Provenance is the product, not a feature on top of it.
Identities. Buyers receive events. This is enforced in the schema, not only in the contract.
Real-time monitoring to law enforcement without a warrant and public transparency.
Data as a settlement or resolution source for prediction markets.
