```sh
zero fetch --capability fieldpulse-crop-yield-forecast-4265f67d
```

Example prompt: Pull me a full crop yield forecast for US corn this season — I need the USDA WASDE and FAO supply/demand synthesis, production estimates, price implications, and a regional breakdown so I can make a trading decision.

## When to prefer this

Use this endpoint when you need a comprehensive, multi-source yield forecast that integrates both USDA WASDE and FAO data for a specific crop, including price implications and regional breakdowns — ideal for grower decision-making or ag-trader positioning rather than just raw weather or soil data.

## Known failure modes

- Unsupported or unrecognized crop name returns an error or empty result
- Region not covered by USDA/FAO data may yield incomplete regional breakdown
- Stale or delayed WASDE/FAO data if underlying source hasn't published latest report
- Missing required crop parameter returns a 400-level error
- Rate limiting or payment failure returns a 402 or 429 response

## How this service works

Crop yield forecast for grower and ag-trader agents. Synthesizes USDA WASDE and FAO supply/demand, production estimates, price implications, and a regional breakdown for any major crop.

## Output

A structured yield forecast report including synthesized USDA WASDE and FAO supply/demand data, production estimates, price implications for the crop, and a regional breakdown covering major growing areas for the requested crop.
