Geospatial data,
served.

One URL schema for public soil, agriculture, water, energy, weather, and political data — every endpoint returns a standards-compliant GeoJSON FeatureCollection. AgSci's PostGIS warehouse plus best-of-breed US Government ESRI services, behind a single host.

What's in the catalog

Five themes, one URL schema. Pass an extent envelope or a wkt geometry; get a standards-compliant GeoJSON FeatureCollection back. Full endpoint reference lives in the API docs.

Soils

Everything about what's growing where, on what soil. SSURGO polygons, horizons and yields; USDA Common Land Units and detected crop boundaries; the Cropland Data Layer with a two-model XGBoost rotation predictor that returns a ranked crop-insurance menu; plus a geometry helper for acreage.

Hydrology

Surface water and floodplain data — NWI wetlands, FEMA flood hazards and FIRM panels (vector + raster + MVT), and the USGS Watershed Boundary Dataset HUC-12 subwatersheds.

Explore 7 endpoints in the API docs →

Weather

Live NWS gridpoint and forecast wrappers — no API key, point or station-based lookups suitable for ad-hoc decision support.

Explore 3 endpoints in the API docs →

Infrastructure

Energy infrastructure from public utility datasets — transmission lines, substations, wind farm footprints and individual turbine locations.

Explore 4 endpoints in the API docs →

Political

Administrative and cadastral boundaries — Census-derived county, state, and county-subdivision lookups, plus the Public Land Survey System (townships, ranges, sections) from both AgSci's bundled database and the FEMA-hosted ESRI service.

Pricing

Simple, transparent per-call pricing in USDC — three tiers, billed per successful call through the x402 marketplace.

Base
$0.002 / call
Free public data, one consistent API

Free public datasets served through third-party ArcGIS services — weather, survey grids, and administrative boundaries. You’re not paying for the data; you’re paying for a single, consistent API — one schema and one query pattern over sources otherwise scattered across separate government servers.

Standard
$0.005 / call
AgSci-hosted database reads

SSURGO soils, the Cropland Data Layer, Common Land Units, wetlands, and spatial operations — read from AgSci’s own PostGIS warehouse.

Premium
$0.010 / call
Frequently-updated & compute-heavy data

FEMA flood hazards, topography, and climate — data that changes often or is expensive to compute per call.

How it works. Every call carries a consumer credential through the AgKit.io x402 marketplace — endpoints resolve to catalog items, requests are identified at the gateway, and usage is recorded per consumer. Want a credential? [email protected].
New: MCP connector. Claude and other MCP clients can query this gateway directly. The agent browses the catalog, then fetches any dataset by geometry. The tool surface is generated from the live catalog, so it reflects what your credential covers. Responses carry each dataset's known caveats, because public geospatial data is easy to misread. Uses the same credential as above. Ask for a connector URL.
