# Get Case Status

> Poll the execution status of a case

Check the current execution status of a case. Poll this endpoint until the case reaches a terminal status, then fetch the output via [Get Case Results](/api-reference/v1-case/get-case-results).

## Path Parameters

<ParamField path="caseId" type="string" required>
  The case ID returned by [Initiate Case](/api-reference/v1-case/initiate-case)
</ParamField>

## Headers

<ParamField header="x-service-key" type="string" required>
  Your API authentication key
</ParamField>

## Response

<ResponseField name="status" type="string" required>
  Execution status of the case. One of: `PENDING`, `IN_PROGRESS`, `WAITING`, `COMPLETED`, `FAILED`, `CANCELLED`, `TIMED_OUT`, `UNKNOWN`.
</ResponseField>

<Note>
  Terminal statuses are `COMPLETED`, `FAILED`, `CANCELLED` and `TIMED_OUT` — once one of these is returned, the status will not change again.
</Note>

## Errors

<ResponseField name="401" type="Unauthorized">
  Missing, invalid, or expired API key.
</ResponseField>

<ResponseField name="404" type="Not Found">
  The case does not exist.
</ResponseField>
