# TELAGO Korea Last-Meter Service Time Estimator

> TELAGO Korea Last-Meter Service Time Estimator is a paid API for AI agents from telago-x402-discovery.vercel.app, paid per call via x402, $0.01/call, status unknown (last checked 2026-10-13).

Estimates the service time (in seconds) to complete last-meter delivery or field service at a specific Korean location, floor, and delivery mode.

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-last-meter-service-time-estimator-5b8066e0 -d '<json body>'
```

Example prompt: How long will it take to complete a MOTORCYCLE delivery of a MEDIUM package to the 8th floor of 123 Teheran-ro, Gangnam-gu, Seoul (37.5013, 127.0394)?

## When to prefer this

Choose this endpoint when you need a fast, pay-per-call estimate of last-meter or on-site service time for a specific Korean address and floor, particularly for logistics planning, field service scheduling, robotics dispatch, or cross-border delivery ETA calculation. Prefer it over generic mapping APIs when you need Korea-specific building access and floor-level intelligence rather than just street-level routing.

## Known failure modes

- Invalid coordinates (latitude or longitude out of range) — validation error returned
- Floor value outside allowed range (-10 to 200) — schema validation failure
- Address string too short or too long — rejected by minLength/maxLength constraints
- Unknown or unsupported delivery mode or package class enum value — bad request
- Location outside Korea or in an area without coverage — low confidence or error response
- Payment failure via x402 protocol — call not executed, 402 response returned

## 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 an 'ok' boolean flag and an 'estimate' object containing 'serviceSeconds' (integer number of seconds to complete the last-meter service) and a 'confidence' score (float 0–1) indicating how reliable the estimate is for that location and configuration.
