Overview

Kakao Maps API provides comprehensive mapping services for South Korea, including map display, address search, route calculation, and keyword-based place search. It is the dominant mapping platform in Korea with highly accurate local data. English documentation is available, but the API is primarily designed for Korean-language projects.

Beginner Tip

Create a Kakao developers account at developers.kakao.com and register an application to obtain your REST API key. Be sure to add your service domain to the allowed origins in the app settings to avoid authentication errors.

Common Errors & Troubleshooting

401 Unauthorized The Authorization header is missing or the key format is incorrect.
✓ Include the header as Authorization: KakaoAK YOUR_REST_API_KEY in every request.
403 Forbidden - domain not registered The calling domain is not registered in your Kakao app settings.
✓ Add your domain (e.g. localhost:3000) to the allowed Web platform list in the Kakao developers console.

✓ Broaden the search query or use a Korean-language keyword for better coverage in the Korean dataset.

Metadata Score Breakdown

Estimated from metadata — endpoint not independently tested

This score is estimated from observable metadata — HTTPS support, authentication model, declared CORS, and documentation reachability — because the API requires authentication or exposes no publicly testable endpoint. The five-signal breakdown is only shown for live-tested APIs.
