Developer preview

Preview ingest format

A short trip format for the public estimator preview. It is not a full production integration, and it is not a phone-tracker export.

Distance used

500 km

The preview uses at most the first 500 km. Uploads are not kept. Oversized requests are rejected simply.

Keep the preview small

What this is

Send a short trip record. The preview checks the shape, does not keep the upload, and does not set insurer pricing.

Start with one trip

Name the vehicle, trip, and UTC start and end times before adding positions.

Add the positions you can share

Map latitude, longitude, time, and speed here. Other fields can wait for a full integration.

Checked, not kept

The estimator reads the request for the preview response and does not store the uploaded file.

After the preview

A full integration covers sampling quality, field coverage, and operating gaps. We sort that with you after a demo.
