        "longDescription": "Helious is a US market data desk your AI can read directly. Every economic release is captured when it prints and scored against its own history, so a CPI or payrolls number arrives with the forecast, the surprise in standard deviations, and where the level sits in decades of official data. Treasury auctions come back shortly after the close with the tail, the bid-to-cover and who bought. Yields carry the curve regime and the time it last flipped.\n\nConnect it and ChatGPT gains 25 read-only tools: Treasury yields and the whole curve, curve regime history, the official 17:00 closes, the economic calendar with scored results, every series Helious tracks in depth, auction results, Fed rate-cut and hike odds from the futures strip, the SOFR and fed funds rate path, the FOMC roster, digests of FOMC minutes and central bank speeches, the FX momentum and volatility boards, cross-asset correlations, the NASDAQ-100 board, mega-cap earnings, Strait of Hormuz tanker transits, the Helious news feed, and transcribed live events.\n\nEach answer leads with a plain-English sentence, names Helious as the source and links the page the number lives on, so you can check it yourself. Numbers travel with their history: a 52-week range and percentile on a yield, twelve-auction averages on an auction, the rank of a print against its own series.\n\nHelious captures these figures first-hand from the publishing source. It is a primary source, not an aggregator of other outlets.\n\nSigning in connects your Helious account, and what each tool returns follows that account. The sign-in is OAuth and read-only: the connection cannot change your account or settings, and you can disconnect it from your account page at any time.\n\nHelious provides market information for educational purposes. Nothing it returns is investment advice.",
