How this service works
Market & brand sentiment for any keyword, brand, ticker or product: analyses the sentiment of web & news content mentioning it and returns an overall label (positive/negative/neutral/mixed), a net sentiment score (-1..1), positive/negative/neutral shares and an emotion breakdown (anger, happiness, love, sadness, fun).
Output
Returns a sentiment assessment for the provided keyword, likely including a sentiment label (positive, negative, neutral) and possibly a numeric sentiment score or confidence metric indicating the current public or market perception of the brand, ticker, product, or topic.
Example use cases
Pre-trade sentiment check
“Before I buy into NVIDIA, can you check the current market sentiment around NVIDIA — is the overall vibe bullish or bearish right now?”
Brand reputation monitoring
“I'm about to run a PR campaign for Tesla — can you pull the latest brand sentiment score for Tesla so I know what public perception looks like heading in?”
Crypto mood analysis
“What's the current sentiment around Ethereum? I want to know if the community is feeling positive or negative about it before I adjust my portfolio.”
Technical details
Endpoint
POSThttps://sentiment.openverbs.com/v1/sentiment?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a quick, single-keyword sentiment read on a brand, stock ticker, crypto asset, or product topic — especially in financial, marketing, or competitive intelligence workflows where understanding public mood is a prerequisite for action. Prefer this over social media scraping or manual analysis when you need a fast, API-ready sentiment signal without building your own NLP pipeline.
Side effects
- Empty or missing keyword returns validation error
- Keyword too long (exceeds 200 characters) triggers schema rejection
- Obscure or very niche keyword may return low-confidence or neutral sentiment due to insufficient data
- Payment failure via x402 protocol results in 402 response before sentiment is returned
- Rate limiting may apply for high-frequency polling of the same keyword
