Han River Water Level

nomadamas/k-skill
2.2k installs5.3k stars
Summary

This pulls real-time water level and flow rate data from the Han River Flood Control Office for specific observation stations in Korea. You ask by station name like "한강대교" or by station code, and it hits a proxy endpoint that handles the upstream API key for you. The proxy returns current water level in meters, flow rate in cubic meters per second, and relevant alert thresholds. If your query is too broad it'll give you a list of candidate stations to pick from. It's a straightforward wrapper around Korean government hydrological data, useful if you're building anything that needs to track Han River conditions without dealing with the HRFCO API directly.

Han River Water Level

What this skill does

기본적으로 https://k-skill-proxy.nomadamas.org/v1/han-river/water-level 로 요청해서 현재 수위와 유량을 요약한다.

When to use

  • "한강대교 지금 수위 어때?"
  • "잠수교 유량 알려줘"
  • "1018683 관측소 현재 값 보여줘"

Inputs

  • 기본 입력: 관측소명/교량명(stationName)
  • 대체 입력: 관측소코드(stationCode)

Prerequisites

  • optional: jq

Default path

추가 client API 레이어는 불필요하다. 그냥 프록시 서버에 HTTP 요청만 넣으면 된다.

사용자는 별도 HRFCO ServiceKey 를 준비할 필요가 없다. upstream key는 proxy 서버에서만 주입한다.

KSKILL_PROXY_BASE_URL 환경변수가 있으면 그 값을 사용하고, 없으면 기본 경로 https://k-skill-proxy.nomadamas.org 를 사용한다.

Example requests

curl -fsS --get 'https://k-skill-proxy.nomadamas.org/v1/han-river/water-level' \
  --data-urlencode 'stationName=한강대교'

관측소코드로 바로 조회해도 된다.

curl -fsS --get 'https://k-skill-proxy.nomadamas.org/v1/han-river/water-level' \
  --data-urlencode 'stationCode=1018683'

Keep the answer compact

응답에는 아래만 먼저 정리한다.

  • 관측소명 / 관측소코드
  • 관측 시각
  • 현재 수위(m)
  • 현재 유량(m^3/s)
  • 기준 수위(관심/주의/경보/심각) 중 값이 있는 항목

Ambiguous station names

입력이 너무 넓으면 proxy 는 ambiguous_station 과 함께 candidate_stations 를 돌려준다.

curl -fsS --get 'https://k-skill-proxy.nomadamas.org/v1/han-river/water-level' \
  --data-urlencode 'stationName=한강'

이때는 후보 중 하나를 골라 다시 stationName 또는 stationCode 로 조회한다.

Detailed API paths

구현 세부는 아래 문서만 참고한다.

  • docs/features/han-river-water-level.md
  • docs/features/k-skill-proxy.md

Failure modes

  • 관측소명이 너무 넓어서 여러 관측소가 동시에 잡히는 경우
  • 잘못된 관측소코드/관측소명으로 station lookup 이 실패하는 경우
  • 프록시 서버에 HRFCO_OPEN_API_KEY 가 비어 있는 경우
  • 실시간 자료 갱신 지연으로 최신 10분 자료가 비어 있는 경우

Notes

  • 기본 경로는 항상 k-skill-proxy.nomadamas.org 의 water-level endpoint 다.
  • upstream 은 waterlevel/info.json 으로 관측소 메타데이터를 찾고, waterlevel/list/10M/{WLOBSCD}.json 으로 최신값을 조회한다.
  • 결과는 원시자료 기반이므로 조회 시각을 함께 적는다.
