Implement a parametric insurance trigger evaluation and automatic payout using a weather index API

Steps

1. Define the parametric trigger: index type (e.g., wind speed, rainfall, temperature), measurement station or grid point, threshold value, and policy period
2. Subscribe to or poll an authoritative weather data API (e.g., NOAA, DTN, The Weather Company) for the relevant index measurements at the policy location
3. At measurement intervals, compare the observed index value against the trigger threshold and record each observation with timestamp and data source
4. When the trigger condition is met (e.g., sustained wind speed exceeds threshold at the agreed measurement point), log the trigger event and initiate the claims workflow
5. Calculate the payout amount per the parametric schedule: linear, step-function, or cap-and-floor structure defined in the policy terms
6. Initiate the automatic payment via the disbursement API without requiring a loss assessment or traditional claims process, and notify the insured of the payout
