# Issue Kind – Training/Evaluation Text Overlap Detector

> Issue Kind – Training/Evaluation Text Overlap Detector 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).

Detects text overlap between training and evaluation sets for issue-kind classification (bug/request/question/other) using a local naive-Bayes baseline.

Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently.

## 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-training-evaluation-text-overlap-detector-2bf34d8e -d '<json body>'
```

Example prompt: Check whether any of my labelled issue records overlap with my evaluation texts — here are 12 training records labelled as bug, request, question, or other, and 2 evaluation documents I want to test against.

## When to prefer this

Choose this endpoint when you need a lightweight, local assessment of training-evaluation text overlap for an issue-kind classifier (bug/request/question/other) without requiring a hosted model or foundation-model training. Ideal for small datasets up to 200 records where data leakage detection is the primary concern and cost sensitivity matters ($0.01 per call).

## Known failure modes

- Fewer than 2 records supplied — validation error
- More than 200 records or evaluation texts supplied — rejected with maxItems error
- Record missing required 'id', 'text', or 'actual' field — schema validation failure
- Invalid label value outside bug/request/question/other enum — rejected
- Text exceeding 1000 characters per record — truncation or rejection
- Empty evaluation_texts array — validation error

## How this service works

Issue kind - Training evaluation text overlap: Training evaluation text overlap 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 training evaluation text overlap deliverable.

## Output

A bounded deliverable reporting text overlap between the supplied labelled training records and the evaluation texts, including identified overlapping entries and leakage metrics derived from a local naive-Bayes baseline analysis.
