seoul-subway-arrival

The seoul-subway-arrival skill provides real-time Seoul subway arrival information by querying the official Seoul Open Data Plaza subway arrival API through a hosted proxy service. It is designed to help users quickly check when trains are arriving at a specific station, which trains are currently approaching, and how soon the next subway is expected to arrive. The skill simplifies access to live transit data by handling API communication through a proxy layer, allowing users to retrieve subway arrival updates without managing personal API credentials or exposing upstream keys on the client side.

The skill supports station-based arrival lookups and can optionally limit the number of returned results. It resolves the proxy endpoint automatically using the optional KSKILL_PROXY_BASE_URL environment variable, defaulting to the hosted proxy service when no custom configuration is provided. The workflow includes querying a read-only arrival endpoint, summarizing important arrival details such as subway line, travel direction, arrival messages, and estimated arrival times when available, and presenting the information with a retrieval timestamp because the underlying data changes frequently in real time. The skill also supports optional response range controls through startIndex and endIndex parameters.

This skill is useful for commuters, travelers, transit assistants, and applications that need quick access to live Seoul subway timing information. It is especially helpful for Korean-language transit queries such as checking arrival times at stations like Gangnam, Seoul Station, or Jamsil. Developers integrating Seoul transit information into AI assistants, chatbots, or transportation dashboards can also use this skill to provide concise, real-time subway updates while keeping upstream API credentials securely managed on the proxy server.
