Parametric Trigger Payout Calculator

Evaluates parametric insurance triggers and computes payout amounts. Supports three trigger types: threshold (binary payout at a threshold index level), tiered (step-based tiers), and linear index (proportional payout between threshold and exhaustion). Produces a tamper-evident trigger receipt anchored at anchor.ainumbers.co for neutral dispute adjudication (IAIS ICP 19). Use with cat bond trigger validation (art-252).

Trigger Configuration
threshold: full payout if index ≥ threshold. tiered: lookup table payout %. linear_index: proportional payout between threshold and exhaustion.
Measured index value at trigger evaluation date (e.g. wind speed in knots, rainfall in mm, earthquake Mw).
Index level at which coverage activates. For linear triggers: lower bound (payout starts here).
Coverage
Maximum policy coverage amount in USD.
Maximum payout cap. Leave blank to use coverage amount.
Trigger Receipt

Copy this paragraph into Claude, OpenClaw, or any MCP-aware agent to run this exact tool, with this sample, and verify the artifact.

  
Run the AINumbers MCP tool `compute_parametric_trigger_payout`. Task: Evaluate parametric insurance triggers and computes payout amounts.
Call it with arguments: {"policy_parameters":{"trigger_type":"threshold","index_value":120,"threshold":100,"coverage_amount":50000,"parametric_limit":50000}}
Verify before trusting: call `verify_execution_hash` on mcp.ainumbers.co (https://mcp.ainumbers.co/mcp) with the parameter `claimed_hash` set to the returned `execution_hash`, passing the full artifact the run returned (the object containing `policy_parameters` + `output_payload` + `execution_hash`; equivalently `policy_parameters` + `output_payload` with `claimed_hash`), not the bare hash string.
Return the ledger link https://ledger.ainumbers.co/ so a human can re-verify without contacting us.
