Technical details
Endpoint
POSThttps://sentimentalpha.ai/v1/reputation-alphaWhen to prefer
Choose this endpoint when you need real-time social sentiment from X/Twitter specifically for trading or investment decisions, especially when you want early detection of narrative shifts before mainstream financial data providers pick them up. Prefer over general-purpose sentiment APIs when the entity is a stock ticker, crypto token, or public figure with trading relevance, and when x402 micropayment infrastructure is already in use.
Side effects
- Unknown or too-obscure entity yields low-confidence or empty sentiment data
- Grok API downtime causes service unavailability
- Ambiguous query string without entity_type leads to misclassified or mixed results
- Rate limits or payment failures (x402) block repeated rapid calls
- Very recent or breaking events may not yet have sufficient X volume for reliable signals
