How this service works
Pay-per-call financial data. Streamable HTTP MCP. x402 USDC on Base. Not financial advice.
Output
Returns a JSON object with a numeric sentiment score (e.g. 0.82 on a 0-1 scale), a human-readable sentiment label (e.g. 'positive', 'negative', 'neutral'), and a source identifier ('NEXUS').
Example use cases
Earnings call tone detection
“Analyze the sentiment of this excerpt from Tesla's latest earnings call: 'Margins remain under pressure and we expect delivery volumes to disappoint relative to prior guidance.' Is it positive or negative and what's the score?”
Financial news headline screening
“Score the sentiment of this headline for me: 'Retail sales beat expectations for third consecutive month, fueling optimism about consumer resilience.' I want to know if it's bullish or bearish.”
Social media market mood tracking
“What's the sentiment score for this Reddit post about Bitcoin: 'Another day, another rug pull — I'm done holding alts, moving everything to cash'? Is it positive, negative, or neutral?”
Technical details
Endpoint
POSThttps://nexus-agent-xa12.onrender.com/sentimentWhen to prefer
Choose this endpoint when you need a quick, pay-per-call sentiment score on financial or market-related text without committing to a subscription. At $0.002 per call it is cost-effective for sporadic or high-volume agentic workflows that already support x402 USDC payments on Base. Prefer it over general-purpose NLP APIs when you want a lightweight, streaming-compatible MCP integration for financial text sentiment specifically.
Side effects
- Empty or missing 'text' field returns a validation error
- Overly long text inputs may be truncated or rejected
- Payment failure via x402/USDC on Base results in a 402 response and no analysis
- Service unavailability on Render.com hosting may cause intermittent 503 errors
- Non-English text may produce unreliable or low-confidence scores
