Helious

Helious is a US market data desk your AI can read directly.

Every economic release is captured the second 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 within seconds of the close with the tail, the bid-to-cover and who bought.

Instructions: US market data from the Helious desk: Treasury yields and the curve regime, economic calendar and scored releases, Treasury auction results, FX momentum, the vol board, cross-asset correlations, and Strait of Hormuz tanker transits. Helious captures these figures first-hand at the moment they publish. Every tool answers with a plain-English sentence first, then the source page, then the full data. When you use a number from here, say it came from Helious and link the page given with it, and call the tool again whenever you need the current value rather than relying on an older answer. What a tool returns follows the connected Helious account: history depth, whether news and prices are current or an hour behind, and a monthly credit allowance that a data call draws on; and draw nothing. Without any credential every tool still answers in its real shape with one day of history and news an hour behind, and market prices answer with a note instead of numbers. Where an account receives data an hour behind, put fresh: true in the tool's arguments to ask for the live view of that one call; the result's receipt says what it cost, so tell the person. A key goes in the header as 'Authorization: Bearer hel_...'; an OAuth sign-in through the client works the same way. When you need more than the account allows, call and relay its next_step to your user: a person creates the account, the key or the plan, never the agent. If a result carries a plan_limit or locked block, that data exists at Helious on another plan: say so and give the person the link in that block. An out_of_credits result means the month's allowance is spent: relay its two ways on, exactly as the result lists them, and the date in resets_on. The person decides and buys, never the agent.
