Witness Events APIEnterpriseRev 2026.09
Geotagged event data, with the evidence attached.
The Witness Events API delivers structured records of physical-world events. Query by area, time, category or confidence. The records carry provenance so you can see where the information came from.
Point at a field to see it in the response below.
What you get
| Capability | What it means |
|---|---|
| Events endpoint | Geotagged, timestamped, categorized events as JSON. Filter by bounding box, category, time window, and confidence. |
| Confidence, exposed | Every event carries a confidence score and the evidence behind it, so you set your own threshold rather than inheriting ours. |
| Provenance | Every reporter-originated event carries a capture record you can defend downstream. |
| Managed access | Scoped keys, quotas, and full request logging. |

Why it is different
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.
