GetCountryChokepointIndex returns per-chokepoint exposure scores for a country. PRO-gated. Requires entitlement tier >= 1.

## Query parameters

- `iso2` string, required
- `hs2` string
- `jmespath` string

## Response `200`

OK

- WorldmonitorSupplyChainV1GetCountryChokepointIndexResponse: GetCountryChokepointIndexResponse returns exposure scores for all relevant chokepoints.
  - `iso2` string: ISO 3166-1 alpha-2 country code echoed from the request.
  - `hs2` string: HS2 chapter used for the computation.
  - `exposures` WorldmonitorSupplyChainV1ChokepointExposureEntry[]
    - `chokepointId` string: Canonical chokepoint ID from the chokepoint registry.
    - `chokepointName` string: Human-readable chokepoint name.
    - `exposureScore` number, double: Exposure score 0-100; higher = more dependent on this chokepoint. With bilateral product data, sums routeCoverage * exporterShare * productWeight * 100 across matching products; fallback uses route overlap only. HS2 27 supported energy chokepoints receive a 1.5x boost capped at 100.
    - `coastSide` string: Which ocean/basin side the country's ports face (atlantic, pacific, indian, med, multi, landlocked).
    - `shockSupported` boolean: Whether the shock model is supported for this chokepoint + hs2 combination.
  - `primaryChokepointId` string: Canonical ID of the chokepoint with the highest exposure score.
  - `vulnerabilityIndex` number, double: Composite vulnerability index 0-100: top1 * 0.5 + top2 * 0.3 + top3 * 0.2.
  - `fetchedAt` string: ISO timestamp of when this data was last seeded.

## Other responses

- `400`: Validation error
- `401`: Missing or invalid API key.
