I built a voice agent for railway train search and information in Hindi. You can ask about whatever place you want to go from your place and it will find you trains in that specific date range. It can reply to you with all available trains. Waiting list, seats available and not available. It also gives you other information about the journey. Tech stack :- Langgraph Python React 19 Typescript FastApi Sarvam api Railkit and railradar api Groq APIs : openai/gpt-oss-120b Langsmith and langgraph internal for observability. Please give your review ! Extra : irctc doesn't have a booking api otherwise I would have integrated that as well   submitted by   /u/Unique-Benefit-2904 [link]   [comments]
