How this service works
X sentiment search / Twitter sentiment monitor / social listening API. Runs X API v2 recent search for a query and scores public posts locally for positive, neutral, and negative sentiment, with result counts and aggregate distribution.
Output
Returns counts of recent X posts classified as positive, neutral, and negative for the given query, along with an aggregate sentiment distribution showing the proportion of each sentiment category across the sampled posts.
Example use cases
Brand reputation check before launch
“Search X for mentions of 'AcmeCorp' and tell me what the overall sentiment looks like — are people mostly positive, negative, or neutral about us right now?”
Campaign reaction monitoring
“I just launched a hashtag campaign called #GreenFuture2025 — can you pull recent tweets about it and show me the sentiment breakdown so I know if it's landing well?”
Competitor sentiment comparison
“How are people on X feeling about 'Notion' lately? Give me the positive, neutral, and negative distribution from recent posts so I can compare it to our own brand sentiment.”

Endpoint
POSThttps://x402.agentutility.ai/x-sentiment?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a quick, cost-effective sentiment snapshot of recent public X posts for a keyword, hashtag, or brand name, and want pre-computed positive/neutral/negative classification without building your own NLP pipeline. It is ideal for agents that need real-time social listening on X without managing X API credentials or sentiment models themselves. Prefer alternatives if you need full tweet text retrieval, historical data beyond recent posts, or sentiment from platforms other than X.
Side effects
- Query returns no recent posts — empty result set with zero counts
- X API v2 rate limit exceeded — upstream API error returned
- Invalid or overly complex search query rejected by X API
- Ambiguous query yields mixed or unexpected sentiment due to topic polysemy
- Service temporarily unavailable if X API credentials are expired or revoked
