# Vault cap usage health

`GET /v3/evk/vaults/health/caps`

Lists vaults ordered by cap-usage severity (descending).
Cap usage is computed as `max(supplyCapUsage, borrowCapUsage)`, and the
response includes both supply-cap and borrow-cap fields.
- `chainId` is required.
- If `threshold` is omitted, returns all vaults.
- Threshold filter is inclusive (`capUsage >= threshold`).
- `onlyOverThreshold` is accepted for compatibility and currently does not alter filtering.

## Query parameters

- `chainId` integer, required
- `threshold` number
- `onlyOverThreshold` boolean
- `offset` integer
- `limit` integer

## Response `200`
