# Knowledge Topic Training-Evaluation Text Overlap Detector

> Knowledge Topic 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 2026-10-15).

Detects text overlap between training and evaluation sets for knowledge topic classification (setup/usage/troubleshooting/reference) using a naive-Bayes baseline, returning leakage metrics.

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 knowledge-topic-training-evaluation-text-overlap-detector-a66c9165 -d '<json body>'
```

Example prompt: Check whether my evaluation texts overlap with my training records for a knowledge topic classifier — I have 12 labelled training documents (split across setup, usage, troubleshooting, and reference categories) and 2 evaluation texts I want to test for leakage.

## When to prefer this

Choose this endpoint when you need a lightweight, cheap ($0.01) check for training-evaluation text overlap in a four-class knowledge topic classification setting (setup/usage/troubleshooting/reference) without needing a hosted model or foundation model. Best for small datasets up to 200 records where data integrity validation is the primary goal, not model training.

## Known failure modes

- Fewer than 2 training records provided — minimum is 2
- Fewer than 1 evaluation text provided — minimum is 1
- More than 200 records or evaluation texts supplied — exceeds maxItems limit
- Record text exceeds 1000 character limit — truncation or rejection
- Invalid category label outside enum (setup/usage/troubleshooting/reference) — validation error
- Missing required fields (id, text, actual) in a record — schema rejection
- Payment not included or insufficient — x402 payment required at $0.01 USDC

## How this service works

Knowledge topic - Training evaluation text overlap: Training evaluation text overlap for Knowledge topic. 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

Returns an overlap/leakage report quantifying how much textual similarity exists between the supplied labelled training records and the evaluation texts, including which pairs overlap and aggregate leakage metrics — all computed locally using naive-Bayes baseline methods without any hosted model.
