OONI Measurement Data and API

Measurements come from volunteer probes worldwide, and the checked API returned archived records beginning 5 December 2012. Accepted measurements are exposed rapidly through OONI Explorer and batched to S3 once an hour; API searches cannot span more than 180 days per request and are not intended for bulk extraction.
