# Check a destination

> Can this destination be calculated, and through which source schedule?

Requires the `calculate:read` scope.

Resolves the shared-source mapping (e.g. `DE` → `EU`) and the calculation
gate — the same logic `POST /calculate` enforces — so integrations can probe
support dynamically instead of hardcoding a country list.

<ParamField path="country" type="string" required>
  ISO alpha-2 destination to probe.
</ParamField>

<ResponseField name="requested_country" type="string">
  The code you asked about.
</ResponseField>

<ResponseField name="source_country" type="string | null">
  The schedule that would answer (e.g. `EU` for `DE`); `null` for an
  invalid code.
</ResponseField>

<ResponseField name="can_calculate" type="boolean">
  Whether `POST /calculate` will accept this destination.
</ResponseField>
