Install Jentic One Beta
Jentic One is a self-hosted execution layer for AI agents. It lets your agent call the Kakao Maps Local API, or any other public or private API you need. You set the rules, the agent never sees your credentials, and every call is logged.
Two steps, two machines. Install the instance in a safe environment, then register your agent from wherever it runs.
Step 1: Jentic One Host machine
# On the machine that will host your Jentic One instance:
curl -fsSL "https://jentic.com/install.sh?src=apis&api=%2Fapis%2Fdevelopers.kakao.com%2Fkakao-main" | shStep 2: Agent machine
# On the machine where your agent runs (keep this separate from the instance):
curl -fsSL "https://jentic.com/install.sh?src=apis&api=%2Fapis%2Fdevelopers.kakao.com%2Fkakao-main" | sh
jentic register # connects your agent to your Jentic One instanceJentic One is in public beta. The setup above keeps your agent separate from the instance, which is what you want before using real credentials: an agent running as the same OS user as Jentic One can read its stored keys directly. Just evaluating? A single local install is fine to start. See the secure deployment guide for the tiers.
What an agent can do with Kakao Maps Local API.
Convert a Korean address string to latitude and longitude through GET /v2/local/search/address.json
Resolve coordinates back to a road or jibun address with GET /v2/local/geo/coord2address.json
Look up the administrative region code for a coordinate via GET /v2/local/geo/coord2regioncode.json
Transform coordinates between WGS84, WCONGNAMUL, CONGNAMUL, WTM, TM, and KTM systems through /v2/local/geo/transcoord.json
GET STARTED
Search places by free-text keyword across the Kakao POI database with GET /v2/local/search/keyword.json
Filter places by Kakao category code (e.g. cafes, hospitals) using GET /v2/local/search/category.json
Patterns agents use Kakao Maps Local API for, with concrete tasks.
★ Korean address validation and geocoding for delivery apps
Korean delivery, ride-hail, and on-demand apps use the address geocoding endpoint to turn user-entered addresses into coordinates that the dispatch and routing engine can consume. Kakao's database is significantly more accurate for Korean road and jibun addresses than global geocoding providers. Integration takes a few hours including registering a Kakao REST API key.
Call GET /v2/local/search/address.json with query='서울특별시 강남구 테헤란로 152' and return the latitude and longitude from the documents array.
POI search for in-app discovery
Apps that show 'cafes near me' or 'hospitals open now' use keyword and category search against the Kakao POI database. Keyword search supports natural-language queries while category search filters by Kakao's two-letter category codes for precise filtering. Both endpoints accept a center point and radius for proximity-based discovery.
Call GET /v2/local/search/category.json with category_group_code='CE7' (cafes), x=127.0276, y=37.4979, and radius=500 to list cafes near Gangnam station.
Coordinate system conversion for legacy GIS systems
Korean public-sector and enterprise GIS systems often use WTM, TM, or KTM coordinate systems rather than WGS84. The transcoord endpoint converts between any pair of supported systems so applications can ingest legacy datasets and emit coordinates compatible with downstream mapping tools. Single-call, no batching required.
Call GET /v2/local/geo/transcoord.json with x=127.108212, y=37.402056, input_coord='WGS84', output_coord='WTM' and return the converted x/y values.
AI-agent location lookups via Jentic
AI agents serving Korean-market applications can call Kakao Maps Local through Jentic to geocode an address or look up a place by keyword without managing the Kakao Authorization header format. Jentic stores the REST API key in your Jentic One instance and exposes high-level intents like 'geocode a Korean address' so the agent passes a string and receives lat/long.
Search Jentic for 'geocode a Korean address', load the schema for GET /v2/local/search/address.json, and execute with the address string from a user form.
6 endpoints — jentic publishes the only available openapi specification for kakao maps local api, keeping it validated and agent-ready.

What agents get from Jentic-routed access to this vendor.
Setup
Wiring the Kakao Maps Local API by hand means composing the 'Authorization: KakaoAK' header, reading the Korean docs, and handling the query parameters for each lookup yourself. Through Jentic you install once, import the Kakao Maps Local API from the API Directory, store the REST API key once, and your agent calls it.
Permission scoping
You choose which Kakao operations the agent may call, so you can limit it to the ones it needs, such as address search and coordinate-to-address lookup, and leave category or keyword search out unless you add them. Every operation is read-only lookup, so the agent cannot render tiles or route navigation.
Credential isolation
Your Kakao REST API key is stored once, encrypted, by your own Jentic One instance and injected at execution time. It never enters the agent's prompt, logs, or context.
Intent-based discovery
Agents search Jentic by intent such as 'geocode a Korean address' or 'search places by category', and Jentic returns the matching Kakao operation with its input schema so the agent calls the right endpoint without browsing the reference docs.

Specific to using Kakao Maps Local API through Jentic.
Why is there no official OpenAPI spec for Kakao Maps Local API?
Kakao publishes Korean-language documentation for the Maps Local API but not a single OpenAPI specification. Jentic generates and maintains this spec so that AI agents and developers can call Kakao Maps Local API via structured tooling. It is validated against the live API and kept up to date. Get started with Jentic One, the self-hosted execution layer.
What authentication does the Kakao Maps Local API use?
The API uses an API key in the Authorization header in the format 'KakaoAK <REST_API_KEY>'. Generate the key from the Kakao Developers console under your application's REST API keys. Through Jentic the key is stored in your Jentic One instance and injected per call.
Can I geocode Korean addresses with this API?
Yes. GET /v2/local/search/address.json accepts a query parameter with a Korean road or jibun address and returns matching documents containing latitude (y) and longitude (x). Kakao's database is the most accurate option for Korean addresses.
What are the rate limits for the Kakao Maps Local API?
Rate limits are not declared in the OpenAPI spec. Kakao applies a per-app daily quota that varies by approval tier. Free-tier apps get a smaller quota than enterprise-tier. Check current quota and remaining requests in the Kakao Developers console.
How do I geocode a Korean address through Jentic?
Run pip install jentic, then with the async client search for 'geocode a Korean address', load the schema for GET /v2/local/search/address.json, and execute with the address as the query parameter. Jentic returns the parsed coordinates.
Does the Kakao Maps Local API support coordinate-system conversion?
Yes. GET /v2/local/geo/transcoord.json transforms between WGS84, WCONGNAMUL, CONGNAMUL, WTM, TM, and KTM. Pass the source coordinate plus input_coord and output_coord values to perform the conversion in a single call.
Can I limit what my agent is allowed to do with the Kakao Maps Local API?
Yes. Because you run Jentic One yourself, you decide which Kakao Maps Local operations the agent may call and set the rules that govern them. You can allow only the endpoints it needs, such as address geocoding (GET /v2/local/search/address.json) and coordinate-to-address lookup (GET /v2/local/geo/coord2address.json), while leaving keyword or category place search out unless you add them. Every Kakao operation here is a read-only lookup, so the agent cannot render map tiles or trigger navigation, and your REST API key stays in your own instance rather than the agent's prompt.
