Endpoint
POSThttps://agents.daedalusdevelopmentgroup.com/v1/treasury-yield-curve?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need official U.S. Treasury par yield curve rates as published by treasury.gov, especially for specific historical dates or months. Prefer it over scraped or third-party rate sources when data provenance and public-domain accuracy matter, or when you need the full maturity spectrum from 1-month to 30-year in a single call via a machine-payable x402 API.
Side effects
