Harvestly Markets

Data Sources & Methodology

Primary source

All 7,083 farmers markets in our directory come from the USDA Local Food Portal, a free public dataset maintained by the United States Department of Agriculture's Agricultural Marketing Service.

How we use it

We pull two USDA endpoints and merge them:

Where both sources have the same field, the live API wins because it's typically fresher. About 80% of markets in our directory have full live enrichment.

Refresh cadence

The directory rebuilds from the USDA's data on a weekly schedule. Individual market profiles update when the USDA refreshes them — which can range from monthly to years, depending on how often the local market manager submits updates to USDA.

What this means for you

Addresses and locations are reliable — once a market registers with USDA, its location rarely changes. Lat/lng coordinates are sourced from USDA directly.

Hours and seasonal dates can drift. Many markets update their USDA listing infrequently. Before planning a trip, we recommend calling ahead or checking the market's own website (when available) for current operating hours.

SNAP/EBT acceptance is generally stable. Markets that participate tend to maintain it; markets that don't rarely add it without promoting the change.
