# Language Routing – Training/Evaluation Text Overlap

> Language Routing – Training/Evaluation Text Overlap 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).

Checks whether evaluation texts appear verbatim or near-verbatim in a labelled training set, detecting data leakage for a language-routing (English/French/Spanish/other) classifier.

## 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 language-routing-training-evaluation-text-overlap-dace4201 -d '<json body>'
```

Example prompt: Can you check whether any of my evaluation texts overlap with my labelled training records? I have up to 200 training examples tagged as english, french, spanish, or other, and I want to know if any evaluation documents leaked into the training set.

## When to prefer this

Use this endpoint when you need to audit a labelled language-classification dataset for train/eval data leakage before model training or benchmarking. Prefer it over generic deduplication tools when your records carry language class labels (english, french, spanish, other) and you need a domain-specific overlap report tied to that classification context. It is especially useful for small dataset validation workflows where a naive-Bayes or local baseline is sufficient and no hosted model is needed.

## Known failure modes

- Fewer than 2 training records supplied — rejected with validation error
- More than 200 records or evaluation texts supplied — rejected with limit error
- Missing required fields (id, text, actual) on any record — schema validation failure
- Invalid language label outside allowed enum — rejected
- Empty evaluation_texts array — rejected
- Timeout if texts are unusually long or numerous near the 200-item limit

## How this service works

Language routing - Training evaluation text overlap: Training evaluation text overlap for Language routing. 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 report identifying which evaluation texts (if any) overlap with records in the supplied labelled training set, including match details and an overall leakage/overlap assessment, helping determine whether the evaluation set is contaminated by training data.
