# TELAGO Korea Address Geocoding API

> TELAGO Korea Address Geocoding API is a paid API for AI agents from telago-x402-discovery.vercel.app, paid per call via x402, $0.001/call, status unknown (last checked 2026-10-13).

Converts a Korean address URL or string into geocoordinates and structured location data for last-mile delivery, field service, and robotics navigation in Korea.

## Facts

- Endpoint: GET https://telago-x402-discovery.vercel.app/korea-address/geocode?utm_source=zero.xyz
- Price: $0.001/call
- Payment: x402
- Status: unknown
- Last checked: 2026-10-13
- Activations on Zero: 0
- Tags: x402
- Canonical page: https://www.zero.xyz/c/telago-korea-address-geocoding-api-54885422
- Structured record (JSON): https://api.zero.xyz/v1/capabilities/cap_HnA3GWx8hl5UC7xszhvRF

Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently.

## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability telago-korea-address-geocoding-api-54885422
```

Example prompt: Can you geocode this Korean address — 서울특별시 강남구 테헤란로 152 — and give me the GPS coordinates so I can route a delivery there?

## When to prefer this

Choose this endpoint when you need precise geocoding of Korean addresses — including jibeon (lot-based) and doro명 (road-name) formats — for use cases like last-mile delivery, field service dispatch, robotics navigation, or cross-border logistics in South Korea. Prefer this over generic geocoding APIs when Korean address format accuracy and last-meter precision are critical.

## Known failure modes

- Invalid or malformed Korean address URL returns an error or empty result
- Address not found in Korean address database returns no coordinates
- Network timeout if the TELAGO service is unreachable
- Payment not processed correctly results in 402 response without data
- Non-Korean addresses may fail resolution or return inaccurate results

## How this service works

Pay-per-call Korea execution intelligence for AI agents: address geocoding, building access, last-meter delivery, field service, robotics and cross-border logistics.

## Output

Returns a JSON object indicating whether the geocoding call succeeded, along with the resolved geocoordinates (latitude/longitude), structured address data, and x402 payment verification metadata including network, asset, and amount paid.
