MacroPulse
Official US macro data read straight from Chainlink contracts. No LLM, no API key. Answers "what is US GDP growth", "current US inflation PCE", "what is SOFR today", "official US economic data". 7 series: real GDP level+growth, PCE index+inflation, real final sales, SOFR. Six are BEA (Dept of Commerce) on Base, SOFR is NY Fed on Ethereum - we assemble both chains. Each value ships its contract + round ID: verify us on an immutable ledger.
