USDA SNAP Retailer Locator

The USDA Food and Nutrition Administration (FNA) - renamed from the Food and Nutrition Service (FNS) on June 1, 2026 - publishes an open, public geospatial API for the Supplemental Nutrition Assistance Program (SNAP) Retailer Locator. The data is hosted as an Esri ArcGIS Feature Service (snap_retailer_location_data) rather than a bespoke fns.usda.gov or api.fns.usda.gov endpoint, and is embedded directly in the public retailer locator tool at fna.usda.gov/snap/retailer-locator. It exposes point-in-time location records - name, address, city, state, zip, county, store type, latitude/longitude, and Healthy Incentive Program participation - for every currently authorized SNAP retailer nationwide (roughly a quarter million records as of the review date), queryable anonymously over REST with no API key, in JSON, GeoJSON, or PBF, with CSV/Shapefile/KML export also available through the ArcGIS Hub item page. Data is refreshed on a recurring basis by FNA; the service is read-only (Query only - no write capabilities).

USDA SNAP Retailer Locator publishes 2 APIs on the APIs.io network: Retailers API and Service API. Tagged areas include SNAP, USDA, Food and Nutrition Administration, FNA, and FNS.

USDA SNAP Retailer Locator’s developer surface includes documentation and 5 more developer resources.

Regulatory Posture applies to this provider. Its tags matched the Government & Public Sector regime, so Regulatory Posture carries 15 points of the composite. If this regime is wrong for your business, say so on your provider repo — the applicability map is public and we will correct it.

Create-or-Update Ergonomics does not apply to this provider. The published contracts declare no write operations, and a read-only API cannot create-or-update. The facet is excluded from this provider's denominator entirely — not scored zero. A reference or data API is not deficient for being unable to upsert.

The six quality facets above are damped to 85 points between them, because the conditional facet above carries the other 15. That is why each facet's contribution is shown against a damped maximum: raising a quality facet moves the composite by 85% of its nominal weight, not 100%. The full arithmetic is at apis.io/rating/.

Improve this rating by publishing the missing artifacts — every area above can be raised, and the full rubric is at apis.io/rating/. Every facet and dimension name above is a link: it opens that measurement's own page — what it means, the exact checks that feed it, how the whole catalog distributes on it, and the providers at the top of it. This rating is computed from github.com/api-evangelist/usda-snap: open an issue to ask a question, or submit a pull request to add artifacts.
