Payment uses the x402 exact scheme: an unpaid call returns HTTP 402 with payment requirements; after paying the exact USDC amount, retry the same request with a payment-signature header and Idempotency-Key. No account and no API key are required. Data sources for this product: Caller-supplied fields, weather, calendars, yields, prices, input costs, grain lots/specs, and insurance evidence Open-Meteo when openMeteo is requested World Bank Open Data when worldBank is requested Limitations: No paid commodity feed or authenticated agricultural platform is used and no API key is required. Missing values are not invented. Yield and cost calculations use only supplied quantities, rates, prices, and optional stress factors.

Market-risk reports aggregate only sections for which records were supplied or optionally fetched. Outputs are compliance prechecks, drafts, or data lookups for human review.
