Include your API key in the Actor input (less secure):

{
"apiKey":"your-kosis-api-key-here",
"searchKeyword":"인구"
}

⚠️ Important: KOSIS API key registration requires Korean identity verification.

1. Visit KOSIS OpenAPI Registration
2. Click "인증키 신청" (API Key Application)
3. Complete identity verification using:
   • Korean mobile phone number, OR
   • i-PIN (Korean digital identity)
