How this service works
Stock Forecast: next-session and 5-day forecast for US stocks/ETFs (SPY, QQQ) from our own candle store and a seeded bootstrap baseline model: direction, probability-of-up share of sampled paths, 80% range, invalidation level, per-step percentiles. Experimental, not calibrated. Not financial advice.
Output
Returns a JSON object containing the forecasted price direction (up/down), probability-of-up as a share of sampled bootstrap paths, an 80% confidence price range, an invalidation level (price at which the forecast is considered failed), and per-step percentile statistics across the forecast horizon for the requested symbol and timeframe.
Example use cases
Pre-market daily outlook check
“Give me today's 1-day forecast for SPY — is it expected to go up or down, what's the probability, and what's the 80% price range I should watch?”
Intraday momentum signal for active trader
“Pull the 15-minute forecast for TSLA right now — I want the predicted direction, the probability-of-up, and the invalidation level so I know where to set my stop.”

Endpoint
GEThttps://quantx402.app/api/v1/stocks/forecast?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need a quick, structured probabilistic price forecast for one of the 11 supported major US stocks or ETFs across standard candle timeframes. It is best suited for agents or traders wanting a statistical directional signal with confidence ranges rather than a qualitative summary. Prefer this over sentiment or news endpoints when you need a quantitative, model-derived forecast with explicit probability and range outputs. Not appropriate for unsupported symbols, crypto, or production trading systems requiring calibrated probabilistic outputs.
Side effects
- Unsupported symbol (only SPY, QQQ, AAPL, NVDA, TSLA, MSFT, AMZN, META, GOOGL, IWM, DIA are supported) returns an error
- Invalid or unsupported timeframe value returns a validation error
- Missing required 'symbol' query parameter returns a 400 error
- Payment failure or insufficient USDC balance prevents call from completing
- Model may not reflect real-time market conditions as it relies on a scheduled candle store
