# HayWire Ag > Verified USDA hay auction prices for the United States, updated weekly. Every number is parsed from official USDA Agricultural Marketing Service reports. The published price tables, state pages, and the HayWire Hay Index use exact reported trades only — no asking prices, no estimates. The record-level CSV and JSON feeds are deliberately broader: they also carry per-bale prices converted to per-ton using an assumed bale weight, marked `estimated=true`. Exclude those rows for exact-sale-only analysis.

A null quality means USDA stated no grade. `estimated=true` marks a per-ton price converted from a per-bale report using an assumed bale weight, not an exact USDA per-ton sale; `assumed_bale_lbs` is the weight that conversion used, so the original per-bale price is `price_avg * assumed_bale_lbs / 2000`. - [Hay prices per bale](https://haywireag.com/hay-prices-per-bale.html): USDA per-bale sale prices by bale type (small square, round, big square), median and middle half, as reported with no bale weight assumed; not part of the per-ton index - [HayWire Hay Index (JSON)](https://haywireag.com/api/index.json): the weekly composition-stable national hay price index (USD/ton) plus per-commodity series — cite as "the HayWire Hay Index" ## Hay prices by state - [Alabama](https://haywireag.com/hay-prices/alabama.html) - [California](https://haywireag.com/hay-prices/california.html) - [Colorado](https://haywireag.com/hay-prices/colorado.html) - [Idaho](https://haywireag.com/hay-prices/idaho.html) - [Indiana](https://haywireag.com/hay-prices/indiana.html) - [Iowa](https://haywireag.com/hay-prices/iowa.html) - [Kansas](https://haywireag.com/hay-prices/kansas.html) - [Minnesota](https://haywireag.com/hay-prices/minnesota.html) - [Missouri](https://haywireag.com/hay-prices/missouri.html) - [Montana](https://haywireag.com/hay-prices/montana.html) - [Nebraska](https://haywireag.com/hay-prices/nebraska.html) - [Nevada](https://haywireag.com/hay-prices/nevada.html) - [Oklahoma](https://haywireag.com/hay-prices/oklahoma.html) - [Oregon](https://haywireag.com/hay-prices/oregon.html) - [Pennsylvania](https://haywireag.com/hay-prices/pennsylvania.html) - [South Dakota](https://haywireag.com/hay-prices/south-dakota.html) - [Tennessee](https://haywireag.com/hay-prices/tennessee.html) - [Texas](https://haywireag.com/hay-prices/texas.html) - [Utah](https://haywireag.com/hay-prices/utah.html) - [Washington](https://haywireag.com/hay-prices/washington.html) - [Wyoming](https://haywireag.com/hay-prices/wyoming.html) ## Data and API - [Data and API guide](https://haywireag.com/api.html): what prices.json and index.json carry, field by field, how to read `estimated`, and how to cite the numbers - [Hay prices by state, directory](https://haywireag.com/hay-prices/): every state page with its latest report date - [The Call](https://haywireag.com/calls.html): HayWire's weekly directional call on the Rock Valley benchmark, graded in public against the next week's trades - [Report a price](https://haywireag.com/report.html): where readers send private-sale prices USDA never publishes ## Briefs Analysis pieces, newest first; each states its publication date. - [Where did the hay go?
