# Deep health check endpoint

`GET /api/v1/health`

## Request

- Base URL: `https://wdk-api.tether.io` (the document declares no server; this is the origin it was published from)
- URL: `https://wdk-api.tether.io/api/v1/health`
- Auth: none declared
- TypeScript: <https://skmtc.dev/tether/apis/wdk-indexer-api/docs/api/v1/health/get.ts> (a function with typed inputs; its response is checked against the schema)

Checks internal dependencies and blockchain indexer sync status. Returns HTTP 200 only when the overall status is `healthy`. Returns HTTP 503 for any non-healthy overall status (`degraded` or `unhealthy`), so readiness probes and load balancers can rely on the HTTP status code alone.

## Response `200`

  - `status` 'healthy' | 'degraded' | 'unhealthy'
