AI Analysis

●●SolidSolve My ProblemBig Brain

Normalizes 6 file formats from 52 issuers into one API — far fresher than quarterly N-PORT.

Strengths
  • •Next-day freshness beats N-PORT's 1-4 month lag for active ETF tracking.
  • •Parsing 6 different file formats from 52 distinct hosts is genuine data engineering work.
Weaknesses
  • •Financial data APIs already exist (Alpha Vantage, IEX Cloud) with overlapping coverage.
  • •Coverage growing but still incomplete compared to full ETF universe.
