Read directly from the server with tools/list, grouped by what they act on. If a tool disappears, we record the date.

crop

get_crop_condition

Most recent weekly NASS crop condition ratings for corn, soybeans, or wheat — the share of the crop rated excellent, good, fair, poor, and very poor, plus a combined good+excellent percentage — from USDA NASS QuickStats. Use for current crop health; use get_crop_condition_history instead for week-by-week change across the season, and get_crop_progress for growth-stage pace. Read-only lookup of stored statistics; no API key. Ratings are published weekly in season, but the stored copy refreshes weekly, so the returned `period` (e.g. 2026-W30) is the freshest stored week, not necessarily the current one.

get_crop_condition_history

Week-by-week NASS crop condition ratings for corn, soybeans, or wheat across the growing season — each week's excellent/good/fair/poor/very poor shares plus a combined good+excellent percentage — from USDA NASS QuickStats. Use to track crop health trends or compare weeks within the season; use get_crop_condition instead when only the latest week matters. Read-only lookup of stored statistics; no API key. Returns up to `weeks` most recent stored weeks, oldest first (default 12, max 52); coverage is the current season, national plus major corn-belt states, and the stored copy refreshes weekly.

get_crop_progress

Most recent weekly NASS crop progress for corn, soybeans, or wheat — the share of the crop at each growth stage (planted, emerged, silking, harvested, and similar; the stages present vary by commodity) — from USDA NASS QuickStats. Use for current season pace; use get_crop_progress_history instead for week-by-week pace across the season, and get_crop_condition for health ratings. Read-only lookup of stored statistics; no API key. Progress is published weekly in season, but the stored copy refreshes weekly; the returned `period` (e.g. 2026-W30) is the freshest stored week.

get_crop_progress_history

Week-by-week NASS crop progress for corn, soybeans, or wheat across the growing season — each week's share of the crop at each growth stage (planted, emerged, silking, harvested, and similar) — from USDA NASS QuickStats. Use to track season pace or compare against earlier weeks; use get_crop_progress instead when only the latest week matters. Read-only lookup of stored statistics; no API key. Returns up to `weeks` most recent stored weeks, oldest first (default 12, max 52); the stages present vary by commodity and point in the season. Coverage is the current season, national plus major corn-belt states, and the stored copy refreshes weekly.

get_crop_stats

Annual NASS survey statistics — yield, production, planted or harvested area — for a commodity at national or state level, from USDA NASS QuickStats. These are survey estimates, not market prices. Use for production fundamentals; use get_crop_condition or get_crop_progress instead for in-season weekly crop status. Read-only lookup of stored statistics; no API key. Returns every stored period (year) for the requested statistic, most recent first; the stored copy refreshes weekly. Commodity, statistic, and geography are case-insensitive and default to CORN, YIELD, and US.

dairy

get_dairy_history

Weekly price history for one dairy product, from the same USDA MARS weekly dairy reports behind get_dairy_price. Use for trends across report weeks; use get_dairy_price instead when only the latest quote matters. Read-only lookup of stored reports; no API key. Returns up to `periods` most recent report rows, oldest first (default 30, max 365); geography defaults to US-Central and cheese reports use geography 'US'. Butter returns a withheld notice — USDA publishes only price differentials for butter, no US base price.

get_dairy_price

Latest price for one dairy product, from USDA MARS weekly dairy reports — the same series get_dairy_history extends over time. Use for a current quote; use get_dairy_history instead for the weekly trend. Read-only lookup of stored reports; no API key. Geography defaults to US-Central (cheese reports are national and use geography 'US'). Butter is deliberately withheld: USDA publishes only price differentials for butter, no US base price, so butter returns a withheld notice instead of a misleading value.

list_dairy_products

Lists the dairy product slugs this API tracks (cheese, butter, dry_whey, fluid_milk) with display labels. Use to discover valid `product` values before calling get_dairy_price or get_dairy_history. Read-only; no API key. Butter is listed for completeness but its price is withheld in the price tools — USDA reports no US base price for butter.

fertilizer

get_fertilizer_history

Price history for one fertilizer product across report periods, from the same twice-monthly USDA MARS production cost reports behind get_fertilizer_price. Use for input-cost trends; use get_fertilizer_price instead when only the latest quote matters. Read-only lookup of stored reports; no API key. Returns up to `periods` most recent reports, oldest first (default 12, max 52 — roughly two years of twice-monthly reports).

get_fertilizer_price

Latest price for one fertilizer product from USDA MARS production cost reports (Illinois-led regional coverage) — the same series get_fertilizer_history extends over time. Use for a current input-cost quote; use get_spreads instead to relate fertilizer cost to corn or cattle prices. Read-only lookup of stored reports; no API key. The reports publish twice a month and are fetched on the 1st and 15th, so the latest price can be up to about two weeks old; returns the price, its unit (typically USD per ton), and the change versus the prior report.

list_fertilizer_products

Lists the fertilizer product slugs this API tracks (anhydrous ammonia, urea, DAP, MAP, potash, liquid N 28/32, ATS, farm diesel, biodiesel) with display labels. Use to discover valid `product` values before calling get_fertilizer_price or get_fertilizer_history. Read-only; no API key. The list is the configured catalog across the tracked MARS production cost reports, not a live availability check.

grain

get_grain_history

Daily cash price history for one grain commodity in one state, from the same USDA MARS daily reports behind get_grain_price. Use for trends or day-over-day comparison; use get_grain_price instead when only the latest quote matters. Read-only lookup of stored reports; no API key. Returns up to `periods` most recent daily report rows, oldest first; `periods` counts report rows, not calendar days (default 30, max 365).

get_grain_price

Latest cash grain price for one commodity in one state, from USDA MARS daily market reports — the same series get_grain_history extends over time. Use for a current quote; use get_grain_history instead for trends across days. Read-only lookup of stored reports; no API key. Returns the most recent report's price with its unit (USD per bushel in most markets) and market location; a commodity/state pair with no report returns a no-data error rather than a stale price.

list_grain_products

Lists the grain commodity slugs this API tracks (corn, soybeans, wheat, sorghum, oats, barley, rice) with display labels. Use to discover valid `product` values before calling get_grain_price or get_grain_history. Read-only; no API key. The list is the configured MARS catalog, not a live availability check — a listed product can still have no report for a given state.

livestock

get_livestock_history

Price history for one livestock category in one region, from the same USDA MARS reports behind get_livestock_price (daily direct-trade reports plus weekly auction summaries). Use for trends; use get_livestock_price instead when only the latest quote matters. Read-only lookup of stored reports; no API key. Returns up to `periods` most recent report rows, oldest first; `periods` counts report rows, not calendar days (default 30, max 365).

get_livestock_price

Latest price for one livestock category in one region, from USDA MARS direct-trade and auction reports — the same series get_livestock_history extends over time. Use for a current quote; use get_livestock_history instead for trends. Read-only lookup of stored reports; no API key. Returns the most recent report's price and its unit (typically USD per cwt); direct-trade reports can skip weeks when no trades occur, and a category/region pair with no report returns a no-data error rather than a stale price.

list_livestock_products

Lists the livestock category slugs this API tracks (fed_cattle, feeder_cattle, cows, hogs, sheep) with display labels. Use to discover valid `product` values before calling get_livestock_price or get_livestock_history. Read-only; no API key. The list is the configured catalog, not a live availability check — some categories trade sporadically and can have no recent report in a region.

wasde

get_wasde_history

Revision history of one WASDE projection figure (default ending_stocks) across monthly reports — how the estimate for a commodity and marketing year moved as successive WASDE reports landed. Use to study estimate revisions; use get_wasde_projection instead for the full current balance sheet. Read-only lookup of stored projections; no API key. Returns up to 24 monthly report values, oldest first, each with its report date and unit, for the requested commodity, attribute, and country (default WORLD).

get_wasde_projection

Latest USDA WASDE supply/demand projections for one commodity — beginning stocks, production, imports, exports, domestic consumption, and ending stocks — from the FAS PSD database behind the monthly WASDE report. Use for the current balance-sheet outlook; use get_wasde_history instead to see how a single figure has been revised across reports. Read-only lookup of stored projections; no API key. Returns the newest stored report's values for the requested marketing year (default: the current marketing year, where e.g. 2026 means the 2025/26 season) and country (default WORLD aggregate; US, BR, and AR are also tracked).

list_wasde_commodities

Lists the commodities tracked in WASDE projections (corn, wheat, soybeans, soybean meal, soybean oil, rice, barley, cotton) with their FAS PSD commodity codes. Use to discover valid `commodity` slugs before calling get_wasde_projection or get_wasde_history. Read-only; no API key.

export

get_export_sales

Latest week of USDA export sales for one commodity from the FAS Export Sales Reporting (ESR) system — sales contracted by exporters, not yet necessarily shipped. Use for current foreign demand; use get_export_sales_history instead for the weekly trend, and get_trade_flows for actual shipped volumes. Read-only lookup of stored reports; no API key. ESR reports weekly (released Thursdays); returns the most recent stored week's weekly exports, outstanding sales, net sales for the current marketing year, and total commitments per destination country, each row with its reported unit. Omit `country` to include all destinations.

get_export_sales_history

Weekly export sales time series for one commodity, and optionally one destination country, from the same FAS ESR weekly reports behind get_export_sales. Use for demand trends across weeks; use get_export_sales instead when only the latest week matters, and compare_contracts_vs_shipments to set contracted sales against actual shipments. Read-only lookup of stored reports; no API key. Returns up to `weeks` most recent weeks, oldest first (default 12, max 52); without a `country`, each week covers all destinations combined as stored.

compare

compare_contracts_vs_shipments

Derived comparison of ESR contracted export sales against GATS actual shipments for one commodity: total contracted, total shipped, and the gap in metric tons — a positive gap means sold but not yet shipped. Use to gauge the unshipped export backlog; use get_export_sales or get_trade_flows instead for the underlying weekly or monthly detail. Read-only; no API key. This is a computed aggregate across both stored datasets over all stored periods, not a USDA-published figure; totals are rounded to whole tons.

esr

list_esr_commodities

Lists the commodities tracked in USDA export sales reporting (wheat, barley, corn, sorghum, soybeans, soybean meal, soybean oil, cotton, rice) with their FAS commodity codes. Use to discover valid `commodity` slugs before calling get_export_sales or get_export_sales_history. Read-only; no API key. Slugs map to FAS 'all' aggregate commodity codes where available.

gats

list_gats_commodities

Lists the commodities tracked in GATS trade flows (matched to Census data by HS chapter) with display labels. Use to discover valid `commodity` slugs before calling get_trade_flows or compare_contracts_vs_shipments. Read-only; no API key. The list is the configured catalog — individual commodities can still be withheld in get_trade_flows when their source data fails sanity checks.

spreads

get_spreads

Derived input-to-output price spreads computed from the latest stored Magpie prices: corn-to-nitrogen cost broken down per fertilizer product (bushels of corn per ton of product and per pound of actual N), the soybean-to-corn price ratio, and the feeder-to-fed cattle spread. Use for planting and feeding economics; use the raw price tools (get_grain_price, get_fertilizer_price, get_livestock_price) instead for the quotes behind a spread. Read-only; no API key. These are Magpie calculations over stored USDA MARS prices, not USDA-published figures; a spread is omitted when either side has no stored price. Geography defaults to IL and applies to both sides of each spread.

trade

get_trade_flows

Monthly US agricultural export shipments by destination, from USDA GATS (Census trade data) — quantities and values actually shipped, not sales contracted. Use for realized trade volumes; use get_export_sales instead for contracted-but-unshipped demand, and compare_contracts_vs_shipments for the sold-versus-shipped gap. Read-only lookup of stored Census data; no API key. Coverage is a rolling 24 months, refreshed monthly; quantities are in metric tons with values in USD. Some commodities are withheld when GATS unit inconsistencies fail a dollars-per-ton sanity check — a withheld result says so explicitly instead of returning bad numbers.
