# Get additional info for a contract

GET https://api.letsdeel.com/rest/contracts/{contract_id}/additional-info

Returns the values a worker submitted for the country-specific additional-information fields on a contract - details local law requires before payroll can run, such as local identifiers, demographic data and emergency contacts. The field set varies per country, so it is kept out of the core contract payload: call this to mirror those values into an external HRIS or payroll system, or to check what a worker supplied during onboarding. Use GET /contracts/\{contract\_id} for the contract terms. EOR and GP.

**Token scopes**: `contracts:read`
