Barley price data: every public source, named
The price series DataCrop ingests for barley, listed by the identifier each publisher uses. Every row we serve carries its own source, that identifier, its unit, its region and its ingestion timestamp — readings are served per identifier, never silently averaged into one number.
Pull it yourself
Every endpoint is Bearer-authenticated; there is deliberately no keyless data route. The free tier covers corn, soybean and wheat with 365 days of history at 500 requests/day for keys created on or after 2026-08-20 (earlier keys stay at 2,000/day).

Forecast status
Barley was dropped from the weekly forecast matrix on 2026-08-12: its primary Montana elevator feed stopped carrying barley on 2026-05-18, so the training target degraded to a stale quote and the pipeline check refused it. Barley price data still ingests daily and is still served through the API — only the modelling stopped.
USDA AMS market reports carrying barley
Report identifiers are the values source_ref carries on AMS rows. Each is checkable at USDA My Market News.
| Report | ID | State | Tier |
|---|---|---|---|
| Montana Daily Elevator Grain BidsPrimary | 2771 | MT | State elevator bids |
| Maryland Grain Bids | 2714 | MD | State elevator bids |
| Minneapolis Daily Grain Report Cash price benchmark for hard red spring wheat (and other grains traded on the Minneapolis Grain Exchange). Reflects exchange/spot prices, not country elevator bids. Comparable to state_bids for the same commodity in the MGE cash area, but the mechanism differs: this is an exchange reference, not a local buyer bid. Do not confuse with slug 3049 (Southern MN state bids). | 3046 | MN | Regional cash |
| California Grain Bids Commodity mix skews toward wheat and barley; corn coverage is sparse relative to Corn Belt slugs. Rice may appear (Sacramento Valley). | 3146 | CA | State elevator bids |
| Portland Daily Grain Bids Pacific Northwest export terminal; the benchmark for soft white wheat exports. Corn and soybean coverage is sparse — this slug is primarily useful for Pacific wheat basis analysis. Not comparable to Gulf export bids (slug 3147): different freight lane, different commodity emphasis, different basis structure. | 3148 | OR | Export bids |
| Virginia Daily Grain Bids | 3167 | VA | State elevator bids |
| Monthly National Mill-Feeds and Miscellaneous Feedstuff Report Mill by-products (middlings, millrun, hulls, meals) plus rows named like raw commodities ("Corn", "Barley") that are delivered feedstock, not market bids. Priced $/ton, ask quotes, F.O.B. Not poolable with any grain-bid tier. | 3667 | market_tier: processor_feedstuff | Processor / feedstuff |
FRED producer-price series for barley
PPI: Farm Products — Grain (group proxy for Barley)
No barley-specific FRED series is active. WPU012 is the broadest grain group aggregate and is accepted as a proxy. Directionally tracks barley but reflects the full grain basket; basis risk applies.
Where our own catalogs disagree
Two files in this repository describe barley: one lists what each publisher offers, the other records which identifier we treat as the default. They do not currently agree. We publish the disagreement rather than pick a winner, because picking one would assert something neither file establishes.
Designated default: WPU01220101. Listed in the source catalog: WPU012.
Identifiers on this page come from the catalog files the ingestion pipeline itself runs on, and change only when the pipeline's own configuration changes. For the full per-source coverage view see data sources, and for the endpoint reference see the API docs.
