# Lead Stage Training Evaluation Text Overlap

> Lead Stage 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 for text overlap between supplied labelled lead-stage training records and evaluation texts using a local naive-Bayes baseline, returning an overlap analysis deliverable.

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 lead-stage-training-evaluation-text-overlap-7e2c1d05 -d '<json body>'
```

Example prompt: Check whether any of my evaluation texts overlap with my labelled training records — I have 50 records labeled as enquiry, qualified, negotiation, or closed, and I want to know if there's data leakage before I trust my model's performance numbers.

## When to prefer this

Choose this endpoint when you need a lightweight, local computation to detect text overlap or data leakage between a labelled lead-stage training set and a separate evaluation corpus, specifically using the four-class schema (enquiry, qualified, negotiation, closed). It is best suited for small datasets (up to 200 records) where no hosted model or foundation-model training is needed. Prefer it over general-purpose similarity APIs when you specifically need CRM lead stage leakage analysis at minimal cost ($0.01 USDC).

## Known failure modes

- Fewer than 2 records supplied — minimum array size not met
- Record text exceeds 1000 character limit — truncation or rejection
- More than 200 records or evaluation texts submitted — exceeds maxItems constraint
- Missing required fields (id, text, actual) on any record — validation error
- Invalid label value for 'actual' field (must be enquiry, qualified, negotiation, or closed)
- Payment not processed — x402 payment required before response
- Empty evaluation_texts array — at least 1 evaluation text required

## How this service works

Lead stage - Training evaluation text overlap: Training evaluation text overlap for Lead stage. 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 the degree of text overlap between the supplied labelled training records and the evaluation texts, including leakage metrics computed locally using naive-Bayes baseline tooling. The response identifies which training and evaluation texts share content, helping users assess whether their evaluation results may be inflated by data contamination.
