# Sentiment Low-Confidence Review Queue

> Sentiment Low-Confidence Review Queue is a paid API for AI agents from market.datapackvibe.com, paid per call via x402, $0.01/call, status unknown (last checked 2026-10-12).

Identifies and queues low-confidence sentiment predictions from a supplied set of labelled text records for human or downstream review, using naive-Bayes baselines.

## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability sentiment-low-confidence-review-queue-879bb18a -d '<json body>'
```

Example prompt: I have 200 labelled sentiment records with their predicted labels and class probabilities — can you run them through the low-confidence review queue so I know which predictions are too uncertain to trust and need a second look?

## When to prefer this

Choose this endpoint when you have a local sentiment dataset with existing predicted labels and class probabilities and need to identify which predictions are too uncertain for production use, without access to a hosted model or foundation-model training pipeline. It is best suited for lightweight model evaluation and QA workflows using naive-Bayes baselines on small datasets up to 200 records.

## Known failure modes

- More than 200 records submitted — request exceeds the maximum batch size limit
- Probability arrays not summing to ~1 or not containing exactly 3 values — schema validation failure
- Invalid or missing enum values for 'actual' or 'predicted' fields — rejected with validation error
- Empty records array — no review queue generated
- Payment not completed via x402 protocol — endpoint returns 402 Payment Required

## How this service works

Sentiment - Low-confidence review queue: Low-confidence review queue for Sentiment. Up to 200 supplied labelled text records. Local dataset tools, evaluation and small naive-Bayes baselines; no hosted model or foundation-model training. One of 25 profiles or calculations across 20 shared operations in this sector. 0.01 USDC includes one bounded low-confidence review queue deliverable.

## Output

A bounded deliverable listing up to 200 submitted records that fall below confidence thresholds, indicating which sentiment predictions are uncertain and should be reviewed. Includes the flagged record IDs, their actual and predicted labels, and associated class probabilities, enabling downstream human review or relabelling workflows.
