Data sources
Where the numbers on AGSIST come from. Last reviewed October 14, 2026. Whether each feed is current right now is on the status page.
Commodity prices
Yahoo Finance (via yfinance)
Used for: Grain, oilseed, livestock, Class III milk, cotton and rice futures; crude oil, natural gas, gold and silver; the Dollar Index, 10-yr Treasury and S&P 500.
Delay: 15 minutes minimum during market hours.
Update frequency: About every 15 minutes while futures markets trade, Sunday evening to Friday afternoon.
finance.yahoo.com: market data via the yfinance Python library.
Bitcoin, XRP and Kaspa quotes on the dashboard come from the same Yahoo Finance feed.
Weather
Open-Meteo
Used for: Hourly temperature, wind speed, wind direction, humidity, precipitation probability, and derived spray/urea risk calculations.
Update frequency: Fetched by your browser each time you open a page or tool that shows weather.
open-meteo.com: open-source weather API.
Windy.com
Used for: The radar map on the home page, embedded from Windy, a private company. Windy draws its radar layer from national weather services, and AGSIST does not process it.
U.S. Drought Monitor (NDMC, USDA, NOAA)
Used for: Weekly U.S. Drought Monitor map embed.
Positioning, hail and transport
CFTC Commitments of Traders
Used for: Weekly managed-money and commercial positioning on the COT page, fetched from the CFTC's public reports each Friday.
NOAA MRMS Radar (MESH)
Used for: Radar-detected maximum hail size swaths on the Hail Map, alongside NWS storm reports and warnings.
USDA AgTransport
Used for: Barge rates, regional grain basis and transport cost indices behind the basis and transport reads.
Prediction markets
Polymarket
Used for: Event probabilities in the odds block on the home page. AGSIST collects them once a day from Polymarket's Gamma API (and Kalshi's public market data) on the server, filters them for farm relevance, and the home page reads that one file. Every contract published today is from Polymarket.
USDA reports
USDA
Used for: Report calendar (WASDE, Crop Progress, Grain Stocks, Acreage, Cattle on Feed), compiled by hand from USDA’s published release schedules (OCE/WAOB and the NASS calendar).
usda.gov: public APIs.
More USDA and government data
USDA NASS Quick Stats and Census of Agriculture
Used for: Yields, acres, cash rents and land values by state and county, including the Census of Agriculture figures on the Farmland Atlas. Pulled from the Quick Stats API.
USDA RMA and FSA
Used for: Crop insurance planting dates, prices and Summary of Business data (Risk Management Agency), and Conservation Reserve Program acres (Farm Service Agency).
USDA FAS Export Sales
Used for: Weekly export sales by commodity, from the Foreign Agricultural Service open data API.
NOAA NCEI and Climate Prediction Center
Used for: Long-run county and state climate records (NCEI) and the 6-10 and 8-14 day outlooks (CPC).
Iowa Environmental Mesonet
Used for: National Weather Service local storm reports, including hail reports, on the Hail Map.
U.S. Energy Information Administration
Used for: Power plant data on the Farmland Atlas (survey EIA-860) and the energy news feed behind the briefing.
Field Scout: USDA soils and Copernicus Sentinel
Used for: Soil maps (SSURGO), crop history (Cropland Data Layer) and Sentinel-1 and Sentinel-2 satellite layers on Field Scout, requested through AGSIST’s own Cloudflare Worker.
Audience numbers
Google Analytics, Search Console and Bing Webmaster Tools
Used for: The reader and search figures on the sponsor page, read from AGSIST’s own analytics accounts. The Bing Webmaster figure counts Bing and Copilot answers only.
Geocoding
Nominatim / OpenStreetMap
Used for: Reverse geocoding browser lat/lng to city, state, and ZIP code. No personal location data is stored on my servers.
Cash bids
AGSIST elevator network
Cash bids come from AGSIST’s own elevator network: bid boards read directly from each elevator. There is no second feed filling gaps, so an elevator the network does not read shows no bid.
