Technical details
Endpoint
POSThttps://sentimentalpha.ai/v1/narrative-alphaWhen to prefer
Choose this endpoint when an AI trading agent needs real-time social sentiment and narrative intelligence from X/Twitter for a specific ticker or market event, especially to detect early trend shifts or contrarian signals before they are reflected in price. Prefer over general-purpose sentiment APIs when financial social arbitrage signals are the primary goal and micropayment-per-call pricing is acceptable.
Side effects
- Invalid or unrecognized ticker symbol returns empty or low-confidence results
- Overly broad free-form queries may return noisy or unfocused sentiment signals
- time_window parameter not specified may default to an undocumented interval
- Rate limiting or micropayment failure via x402/Base USDC may block the request
- Grok API upstream outage could cause degraded or unavailable responses
- Very niche or low-volume tickers may have insufficient X data for meaningful signal
