How this service works
AI-powered stock analysis, technical indicators, sentiment scoring, and portfolio risk. 11 endpoints. Pay per request via x402 on Base chain.
Output
Returns a JSON object with a success boolean and a data object containing AI-derived sentiment metrics for the requested stock ticker, likely including a sentiment score, directional classification (bullish/bearish/neutral), and supporting signals.
Example use cases
Pre-trade sentiment check
“Before I buy more shares of Tesla, can you pull the latest sentiment score for TSLA and tell me if the market mood is positive or negative?”
Portfolio sentiment dashboard
“I want to know the AI sentiment reading for each of my holdings — start with AAPL and tell me whether it's bullish, bearish, or neutral right now.”
Earnings reaction sentiment
“MSFT just reported earnings — can you check the current sentiment score for Microsoft stock to see how the market is reacting?”

Endpoint
POSThttps://alephack.vercel.app/api/sentimentWhen to prefer
Choose this endpoint when you need a fast, per-ticker AI sentiment score for a specific stock and want a pay-per-use model with no subscription overhead. Prefer it over generic news aggregators when you want a pre-computed sentiment signal rather than raw headlines, and over full portfolio analysis endpoints when you only need sentiment (not technicals or risk) for a single symbol.
Side effects
- Invalid or unrecognized ticker symbol returns error or empty data
- Missing required 'symbol' field returns validation error
- Network or upstream AI model latency causing timeout
- Ticker not covered by the sentiment model returns no data
- x402 payment failure or insufficient USDC balance blocks request
