How this service works
Sentiment: a composite market-mood read for one symbol from our own pipeline: model lean, price momentum, and news tone (when our news feed has items). Each component is shown with its inputs. Experimental. Not financial advice.
Output
A composite sentiment object for the requested symbol containing: an overall market-mood score, a model lean component (directional signal from the Kronos model), a price momentum component (recent price trend input), and a news tone component (sentiment from the news pipeline when headlines are available), each with their contributing inputs. Marked as experimental; not financial advice.
Example use cases
Pre-trade sentiment check for crypto
“Before I make a move on ETH, what's the current composite sentiment — is the model leaning bullish or bearish, what does price momentum look like, and how is the news tone?”
Stock mood check before earnings
“Can you pull the market sentiment for NVDA right now? I want to see the model lean, price momentum, and news tone all in one read.”
Daily briefing on market mood
“Give me a quick sentiment snapshot for SPY this morning — I want the composite mood score and what's driving it: model, momentum, or news.”

Endpoint
GEThttps://quantx402.app/api/v1/sentiment?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a single, consolidated sentiment signal that blends multiple signals (model direction, price momentum, news tone) for a supported crypto pair or US stock/ETF, rather than building your own composite from raw data. Prefer it over raw news or pure price feeds when you want an opinionated, pre-aggregated market mood score with component-level transparency. Best for agents making quick sentiment-informed decisions without needing full forecast candles.
Side effects
- Symbol not in supported list — returns error or empty result
- News component absent if no recent headlines exist in the pipeline for that symbol
- Stale or delayed data if upstream market feed is lagging
- Payment failure if USDC balance is insufficient for the $0.01 per-call fee
- Invalid symbol format returns a validation error
