## How to call it through Zero

```sh
zero fetch --capability prereason-grains-agribusiness-dashboard-3ac93b97
```

Example prompt: Pull up the latest grains and agribusiness briefing — I want to see the WEAT ETF price, the World Bank wheat price, and how US grain merchandisers and farmland REITs have performed relative to WEAT over the past year, with their 90-day correlations, in markdown format.

## When to prefer this

Choose this endpoint when you need a consolidated view of the US wheat and agribusiness sector — combining the WEAT ETF, World Bank wheat price, and performance/correlation data for the full chain of US grain-adjacent companies — rather than querying individual company financials or a generic stock price API. Ideal for macro agricultural analysis, sector rotation research, or monitoring how agribusiness equities track wheat futures. Supports historical lookups by date and LLM-optimized markdown output.

## Known failure modes

- Requested date not on record — returns error or empty data for unavailable historical dates
- Invalid date format (not YYYY-MM-DD) — schema validation failure
- Invalid format parameter value — falls back to default or returns error
- Upstream World Bank or market data unavailable — may return partial metrics
- Payment not completed (x402) — request rejected before data is served

## How this service works

Wheat and USA agribusiness side by side. The wheat futures fund WEAT's share price (not the wheat price) and the World Bank's monthly US wheat price, then the covered USA grain merchandisers, seed and crop nutrient companies, farm equipment makers and farmland REITs, each with its share price, its 1, 3 and 12 month changes beside WEAT and the 90 day correlation of its daily changes with WEAT. Commodity and company data for research agents. A paid call serves today or any ?date= on record.

## Output

Returns a structured briefing with the WEAT ETF share price, World Bank monthly SRW wheat price (USD/MT), and for each covered US agribusiness company (grain merchandisers, seed and crop nutrient firms, farm equipment makers, farmland REITs): share price, 1/3/12-month price changes compared to WEAT over the same windows, 90-day daily-change correlation with WEAT, and a reference ID to the company's own detailed briefing. Companies are grouped by category and ordered by market capitalization. Available in JSON or token-optimized markdown format.
