Customer-built analysis

Perplexity: sentiment

Classify how a brand is described using your own analysis pipeline.

Collection target: perplexity. This is customer-built analysis, not a computed API response field.

Build this analysis in your application

Use collected text to distinguish recommendation, neutral description and criticism. Keep the supporting sentence and your classifier version so a human can audit a label.

Customer-built analysis

Nostimates does not return sentiment labels, confidence scores or distributions. Classification uncertainty is separate from collection success.

The perplexity target returns text, markdown, pageUrl and sources with the successful run identity and capture time. Source lists may be empty and response fields may be null. Perplexity may use operator-configured sessions. Availability depends on deployment configuration and provider behavior; no response or citation count is guaranteed.

Collected input for your analysis

These are illustrative successful run excerpts, not full result files or calculated metrics. Submit POST /v1/crawl-jobs, track completion, then download the authenticated result. Outputs depend on the target; a chatbot has no news articles or Google position fields.

Sentiment FAQ

Does the API calculate sentiment?
No. Classify how a brand is described using your own analysis pipeline. The API supplies collected provider outputs; this analysis belongs in your application.
How should failed or empty collections be handled?
Inspect per-target failedRuns and each successful run identity. Empty sources or null fields are valid output; a missing failed run is not an empty successful answer. A completed job can contain failed collections.
