Four data sources, one page, every day

NCSX-IS is event-driven — the level holds between pricings, but the market moves every day. This page assembles the index level, US high-yield OAS (FRED / ICE BofA), the Treasury curve and EDGAR filings of 9 issuers each morning. Data bundle: GET /api/v1/real/daily.json — agents welcome.

Red line: aggregates public data only — no credit ratings, no investment advice. The index is a point-in-time issuance spread (coupon − Treasury at pricing) with no secondary trades; sector OAS and the curve come from FRED / ICE BofA and the U.S. Treasury. This page is a daily snapshot; full history is downloadable from the real data page.
