Price Feed Aggregator Script

Description

Build a Node.js script that fetches RWA token prices from Uniswap, SushiSwap, and Curve, calculates a volume-weighted average price (VWAP), and outputs the result as JSON. Should support configurable token pairs and time windows. Designed to run as a cron job or be called by agents.

Requirements

• Fetch prices from at least 3 DEX sources
• Calculate VWAP across sources
• JSON output with source breakdown
• Configurable token pair and time window

Acceptance Criteria

• Returns valid VWAP within 5 seconds
• Handles source failures gracefully
• Includes confidence score based on volume
• Works as standalone script or importable module
