Developer Docs
AGSIST publishes live agricultural market data and embeddable widgets for ag media, extension services, co-ops, and farm websites. Five widgets are live. Three JSON data feeds are open today. Embed scripts are in development — contact me if you want to integrate early or discuss a custom build.
/api/v1/*.js embed scripts shown below are not yet publicly deployed. The JSON data feeds are live and available now. Email me or call 715-797-2428 for early access or to discuss custom integrations.Widget Showcase — 5 Live, 1 Coming Soon
Live Data Feeds
These JSON endpoints update automatically. Consume them directly to build your own UI without waiting for embed scripts.
