# TELAGO Korea Reverse Geocode API

> TELAGO Korea Reverse Geocode 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 2026-10-17).

Converts GPS coordinates (latitude/longitude) into a normalized Korean address with building-level details including elevator access, floor count, and building name.

## Facts

- Endpoint: GET https://telago-x402-discovery.vercel.app/korea-address/reverse-geocode?utm_source=zero.xyz
- Price: $0.001/call
- Payment: x402
- Status: unknown
- Last checked: 2026-10-17
- Activations on Zero: 0
- Tags: x402
- Canonical page: https://www.zero.xyz/c/telago-korea-reverse-geocode-api-37ac17da

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-reverse-geocode-api-37ac17da
```

Example prompt: What's the Korean address and building details at coordinates 37.4725, 126.9176? I need the building name, number of floors above ground, and whether there's elevator access.

## When to prefer this

Choose this endpoint when you need building-level intelligence (elevator access, floor count, building name) alongside a normalized Korean address from GPS coordinates — especially for last-mile delivery, field robotics, or logistics workflows operating in South Korea. Prefer this over generic geocoding APIs when Korean address normalization and physical building access metadata are both required in a single call.

## Known failure modes

- Coordinates outside South Korea may return no match or incorrect results
- Coordinates in remote or rural areas may lack building-level data
- Malformed latitude/longitude values outside valid ranges (-90 to 90, -180 to 180) will be rejected
- Payment failure via x402 protocol will block the call
- Response may lack building details (elevator, floors) for older or unregistered structures

## 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 with ok status, normalized Korean road address (in Korean script), building name, floors above ground, elevator availability (boolean), distance in meters from the queried point to the resolved address, and the precise latitude/longitude of the matched building.
