Crypto token sentiment before trade
“Before I buy more ETH, can you check the current sentiment score for Ethereum across news and blogs and tell me if it's leaning positive or negative?”
Brand reputation monitoring
“Pull the sentiment analysis for 'Nike' across news and message boards — I want to see the polarity counts and whether there's more anger or happiness in the coverage.”
Trending coin opinion check
“There's a lot of noise around Pepe coin right now — can you analyze the sentiment across blogs and organic results and give me the score plus the emotion breakdown?”

Endpoint
POSThttps://agent-commerce-factory-jm.austriaeast.cloudapp.azure.com/v1/sentiment/searchWhen to prefer
Choose this endpoint when you need multi-source aggregated sentiment (news + blogs + web) with both polarity counts AND emotional connotations in a single call. Ideal for crypto/market sentiment, brand monitoring, and opinion-mining agents that need a composite [-1,1] score rather than raw article text. Prefer over raw news search when you need quantified sentiment rather than article content.
Side effects
- Empty or overly broad query returns noisy or null sentiment data
- Query with no web coverage returns null score fields
- Invalid pageTypes enum value causes request rejection
- Query exceeds 300 character limit returns validation error
- Upstream data source unavailable may return null upstream cost and degraded results
