--- title: Subscribe to Helious Pro description: How to subscribe to Helious Pro ($39.99/mo) and what's included: live news, release breakdowns, auction analysis, Fed-speak, squawk audio, and alerts. source: Helious canonical: https://helious.io/help/subscribe --- # Subscribe to Helious Pro Pro is USD 39.99 a month and turns on the whole terminal. Here's what it unlocks, and where Starter, Ultimate and the free tier sit around it. ## Four plans, one ladder Helious has four plans. A free account costs nothing and gets an API key with 7 days of news history, an hour behind live. Starter is USD 14.99 per month: the news and prints live as they land, plus the US Treasury curve 60 minutes behind. Pro is USD 39.99 per month: every market price live and the entire terminal, squawk included. Ultimate is USD 99 per month: commercial use and a dedicated streaming WebSocket on top. Every plan sees the same endpoints and shapes, so nothing you build breaks on an upgrade. Head to the [live desk](https://helious.io/) and follow the subscribe prompt to start. ## What Pro includes The live news feed is market-moving and de-duplicated, bucketed into tabs: ALL, MOVING, CB TALK, GEO, BONDS, DATA, CHATTER: with a market-impact slider so you can dial out noise. Economic releases arrive as breakdowns seconds after print: actual vs forecast vs prior plus a standardized [surprise z-score](https://helious.io/learn/surprise-z-score) so a beat or miss is measured in sigma, not vibes. See what's on deck on the [economic calendar](https://helious.io/calendar). Treasury auction analysis lands seconds after results: the real when-issued [tail or stop-through](https://helious.io/learn/auction-tail) in basis points, [bid-to-cover](https://helious.io/learn/bid-to-cover-ratio) against its 12-month average, the [indirect](https://helious.io/learn/indirect-bidders) / [direct](https://helious.io/learn/direct-bidders) / [dealer](https://helious.io/learn/primary-dealers) split, and a STRONG / IN LINE / WEAK verdict. Every auction rolls up into the [auction hubs](https://helious.io/auctions) and the [tail dataset](https://helious.io/data/treasury-auction-tails). You also get Fed-speak tracking: officials flagged the moment they speak with a hawk/dove read, tied to the [Fed](https://helious.io/fed) and [FOMC](https://helious.io/fomc) pages, a dual-asset momentum SCORE gauge for bonds and equities, server-side alerts with regime-aware move thresholds and per-symbol arming, a curve and spread board on the [rates](https://helious.io/rates) view, and noise-cleaned live squawk audio. ## How billing works You're charged your plan's price at signup and again on each renewal date, monthly or yearly as you choose. Card details are entered directly into our PCI-compliant payment processor and never touch our servers. You can [cancel anytime](https://helious.io/guides) and keep access through the period you've already paid for. ## Getting started Open the [terminal](https://helious.io/), subscribe, and you're live immediately, no onboarding queue. If you want to see how the pieces fit before you commit, browse the [guides](https://helious.io/guides) and the [methodology](https://helious.io/methodology).
