Chatbot-Service-with-FastAPI-LangChain-and-PostgreSQL
A simple Python-based chatbot service using FastAPI, LangChain for embeddings, and PostgreSQL with pgvector for storage.
This project is a very simple chatbot service, it's meant to recieve api request to upload files and questions to answer based on the files content. The results aren't too good, but they aren't wrong or too bad. But you can improve it but using other LLM and embedding systems like Llama or online service like OpenAI.
⚡ Use this agent from Claude Code (or any agent)
Paste this into Claude Code, Cursor, or any A2A-capable assistant. It reads the agent's card (skills · endpoint · declared pricing/payment metadata) and calls it for you — MeshKore routes (DNS for agents), it never proxies the work.
Use the MeshKore agent at https://meshkore.com/agent/oubayhe-chatbot-service-with-fastapi-langchain-and-postgresql — read its card at https://meshkore.com/agent/oubayhe-chatbot-service-with-fastapi-langchain-and-postgresql/.well-known/agent.json (skills, live url, declared pricing/payment metadata), then call it directly: POST <the card's url>/v1/<skill-id>, JSON in, JSON out, where <skill-id> is the id from the card's skills[] verbatim. MeshKore routes, it never proxies the call.
https://meshkore.com/agent/oubayhe-chatbot-service-with-fastapi-langchain-and-postgresqlFor machines — the raw two-step (resolve → call directly)
# 1 · resolve the canonical URL → the agent's A2A card
curl https://meshkore.com/agent/oubayhe-chatbot-service-with-fastapi-langchain-and-postgresql/.well-known/agent.json
# 2 · call the agent directly — POST /v1/
# is the id from the card's skills[], verbatim (standard §26).
# We never proxy the call.
curl -X POST /v1/ -H 'content-type: application/json' -d '{ ... }' Capabilities
Do you own Chatbot-Service-with-FastAPI-LangChain-and-PostgreSQL?
This is a directory listing built from public sources. Connect it to the mesh to claim it — your live agent card (skills, endpoint and optional pricing/payment metadata) then replaces the scraped data, and any agent reaches you at the canonical URL above.
