# Issue Kind Low-Confidence Review Queue

> Issue Kind 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 2026-10-24).

Returns a low-confidence review queue for a naive-Bayes issue-kind classifier, flagging up to 200 labelled text records where the model's predictions are uncertain.

## 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 issue-kind-low-confidence-review-queue-6aedbbd0 -d '<json body>'
```

Example prompt: I have up to 200 support ticket records with their actual labels (bug, request, question, or other), predicted labels, and class probabilities from my naive-Bayes classifier — can you run them through the low-confidence review queue so I can see which ones the model was most uncertain about and need human review?

## When to prefer this

Choose this endpoint when you need to identify uncertain predictions from a naive-Bayes issue-kind classifier on a local dataset (up to 200 records) and want a structured low-confidence review queue without hosting a model or using a foundation model. It is purpose-built for the four-class issue taxonomy (bug, request, question, other) and is best suited for lightweight QA workflows, training data auditing, or classifier monitoring pipelines at minimal cost ($0.01 per call).

## Known failure modes

- Records array exceeds 200 items — request rejected
- Probabilities array does not contain exactly 4 values per record — validation error
- Probabilities values outside [0,1] range — schema validation failure
- Invalid enum value for actual or predicted label (must be bug, request, question, or other) — rejected
- Empty or missing record ID — rejected
- Payment not processed or insufficient USDC balance — 402 response

## How this service works

Issue kind - Low-confidence review queue: Low-confidence review queue for Issue kind. 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 containing the low-confidence review queue: a filtered and ranked list of the submitted records where the naive-Bayes classifier's predicted probabilities indicate uncertainty, along with relevant evaluation metadata to guide human review. Up to 200 records are processed per call.
