How this service works
Quick opinion triage: labels text POSITIVE or NEGATIVE with confidence plus all scores (DistilBERT SST-2), fixed price $0.005 USDC. Use this for sentiment only, not nuanced moderation or answers (use /chat). POST JSON body {text (required, max 2000 chars)}. Returns {label, score, scores}. Unpaid calls get 402; paid calls settle only on success.
Output
Returns a JSON object with: `label` (string, either 'POSITIVE' or 'NEGATIVE'), `score` (float 0–1, confidence for the winning label), and `scores` (object with confidence values for all classes). On unpaid or failed calls, returns HTTP 402.
Example use cases
Product review sentiment triage
“I have a customer review that just came in — 'Battery life is incredible but the screen scratches way too easily' — can you label it positive or negative and give me the confidence score?”
Social media comment filtering
“Check this tweet for me: 'Can't believe how terrible the support was, waited 3 days and got no reply.' Is it positive or negative, and how confident are you?”
App store feedback scoring
“Run sentiment on this app store review: 'Super intuitive design and blazing fast performance, exactly what I needed.' Give me the label and the full scores.”
Technical details
Endpoint
POSThttps://compute.combify.app/classify?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a fast, cheap, binary sentiment signal (POSITIVE/NEGATIVE) with a calibrated confidence score for short-to-medium text. It is ideal for triage pipelines, review scoring, comment filtering, or any workflow where volume is high and a two-class label suffices. Prefer /chat for nuanced moderation, open-ended questions, or multi-class classification needs. At $0.005 USDC per call it is the lowest-cost option on the platform for opinion detection.
Side effects
- HTTP 402 if payment is not attached or fails — call is not charged on failure
- Text exceeding 2000 characters may be rejected or truncated
- Network timeout for unusually complex inputs
- Invalid JSON body returns a 400-level error
- Model is binary only — nuanced or neutral sentiment cannot be expressed
