What it can do

Tool names and descriptions exactly as the server reported them on Nov 6, 2026. The maker wrote them, not us; we show them as plain text.

• ncsx_latest

  The one number to quote — use this first for "what is NCSX-IS / what is the spread right now". Returns a compact record: headline issuance spread (coupon minus the Treasury yield of matching tenor on the pricing date, weighted by face value), the secured and unsecured sub-indices

• ncsx_index

  The full index definition, not a single number — use when the question is structural ("how is NCSX-IS built", "show all tiers") rather than "what is the level". Returns the NCSX-IS / secured / unsecured tiers side by side with each tier's notional and constituent count, plus inde

• ncsx_constituents

  The whole universe in one response — all 13 constituent bonds, no filter: issuer, ticker, coupon, maturity, size, seniority, pricing date, tenor, the matched Treasury yield on that date, and the resulting issuance spread in bp. Use it to list the index or to compute weights; if t

• ncsx_bond

  Filtered lookup for one issuer, ticker or note keyword (e.g. "CoreWeave", "GLXY", "Helios", "2031") — returns only the matching constituent bonds, not the whole universe. Constituents are identified by issuer + coupon + maturity; they do NOT carry CUSIPs, so never query by CUSIP.

• ncsx_curve

  The US Treasury par-yield curve used on the pricing date (14 tenors, interpolated linearly, never extrapolated) plus its recent history. Every constituent spread is measured against this curve.

• ncsx_sector

  Context series for the AI-infrastructure credit complex: US high-yield OAS, US investment-grade OAS and related ICE BofA indices, with 30-day change and daily history — use these to compare NCSX-IS against the broader market.

• ncsx_filings

  SEC filing radar for the 9 AI-infrastructure issuers covered by SpreadBench (6 in NCSX-IS plus Nebius, IREN and Hut 8 on the watchlist): every filing from the last 45 days, noise forms (ownership, routine) filtered out, pricing-chain forms (FWP, 424B*, S-3*, F-10) flagged with pr

• ncsx_marks

  Second, independent layer: quarterly fair-value marks for AI-infrastructure bonds as reported by US registered funds on SEC Form N-PORT (Level 2), converted to spread over the matched Treasury. Compare with NCSX-IS to see issuance spread vs. mark spread.

• ncsx_methodology

  Methodology metadata and full formula chain: version, DOI, license, data sources and their licensing status, the exact spread and weighting formulas, and what is explicitly NOT measured.
