# AI Dev Tool: Edge Function Vector Search API
# =============================================
# This is a production-ready Edge Function API using Cloudflare Workers, Hono, and PostgreSQL Vector Search Extension.
# It provides a scalable and performant vector search functionality for micro-SaaS applications.

import os
import json
from pydantic import BaseModel
from hono import Hono
from cloudflare import WorkersKV
from psycopg2 import connect
from psycopg2.extras import DictCursor

# Define the Vector Search Request Model
class VectorSearchRequest(BaseModel):
    """Vector Search Request Model"""
    query: str
    limit: int = 10

# Define the Vector Search Response Model
class VectorSearchResponse(BaseModel):
    """Vector Search Response Model"""
    results: list

# Initialize the Hono App
app = Hono()

# Initialize the Cloudflare Workers KV Store
kv = WorkersKV(namespace="vector-search")

# Initialize the PostgreSQL Connection
