# Health Check

GET https://api.zip-tax.com/system/health

Returns the health status of the API and its components

Reference: https://docs.zip.tax/api-reference/system/get-health

## Response

### 200

OK

- `components` (HealthComponents, required) — Per-component health detail.
- `status` (string, required) — Overall health of the API. Always 'ok' on a served response; component-level detail is in the components object.

## Types

### HealthComponents

- `dynamo` (enum, required) — DynamoDB connectivity status: 'ok', 'config_error' (AWS config could not be loaded), or 'connection_error' (table could not be described).
  - Allowed values: `ok`, `config_error`, `connection_error`
- `taxdata` (enum, required) — Tax-data cache status: 'ok', 'empty' (cache not loaded), or 'partial' (fewer than the expected number of records loaded).
  - Allowed values: `ok`, `empty`, `partial`
- `taxdata_count` (long, required) — Number of tax-data records currently loaded in the in-memory cache.
