Product Trial

You can try out Field Explorer by creating a developer account and subscribing on the product page. The trial allows full access to the APIs for a limited number of locations.

Calls to the API products can be made from your coding environment or through this portal.

While logged into this portal, navigate to the API documentation and use the "Try it" button for a particular end-point. The portal will automatically include your trial subscription key in the header of the API call, and display the contents of the API call and response.
From your own development environment, construct a call to the relevant end-point and set header parameters including providing your subscription key. This is visible to you in your profile on this portal.

Trial Access

While on a trial, API access is limited to a selection of predetermined fields:

The fields of Reading University Research Farm (Cedar Farm) near Reading, UK.
The fields of the Rothamsted Research Farm (Hall Farm) near Harpenden, UK.
Eighteen other fields from around the UK.

These fields are shown in the navigable map below, and information about the trial data is available through the data catalogue.

To upgrade to a full subscription, contact Agrimetrics to discuss your needs.

Field Finder has no restrictions, but data is only available for those fields within the trial.
Field Search can search any area, but the results will be restricted to the trial fields.
