# Lead Stage Confusion Matrix

> Lead Stage Confusion Matrix 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).

Computes a confusion matrix for a lead stage classifier across four stages (enquiry, qualified, negotiation, closed) from up to 200 labelled text records.

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-confusion-matrix-e27b6932 -d '<json body>'
```

Example prompt: Here are 150 labelled lead records with their actual stages (enquiry, qualified, negotiation, or closed) and my model's predicted stages — can you compute a confusion matrix so I can see where the classifier is going wrong?

## When to prefer this

Choose this endpoint when you need a structured confusion matrix specifically for a four-class lead stage classifier (enquiry, qualified, negotiation, closed) evaluated on up to 200 labelled text records, and you want a lightweight, bounded computation without needing a hosted model or foundation model training pipeline.

## Known failure modes

- More than 200 records submitted — batch size limit exceeded
- Records missing required fields (id, text, actual, predicted) — validation error
- Invalid label value outside the four allowed enums — rejected input
- Empty records array — no computation possible

## How this service works

Lead stage - Confusion matrix: Confusion matrix 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 confusion matrix deliverable.

## Output

A confusion matrix covering the four lead stages (enquiry, qualified, negotiation, closed), showing counts of correct and incorrect predictions for each class pair, along with derived per-class and overall accuracy metrics.
