# Feedback Theme Supplied-Group Evaluation

> Feedback Theme Supplied-Group Evaluation is a paid API for AI agents from market.datapackvibe.com, paid per call via x402, $0.01/call, status unknown (last checked 2026-10-19).

Evaluates a classifier's performance on feedback theme labels (quality, price, delivery, support) across user-supplied groups using local naive-Bayes 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 feedback-theme-supplied-group-evaluation-0494780b -d '<json body>'
```

Example prompt: Evaluate my feedback theme classifier predictions by group — I have up to 200 records each with an id, the raw feedback text, the actual label (one of quality, price, delivery, or support), the predicted label, and a group tag like 'segment-A' or 'segment-B'. Can you run a supplied-group evaluation and tell me how the classifier performs per group?

## When to prefer this

Choose this endpoint when you have a pre-labelled dataset of customer feedback texts with actual and predicted theme labels and want to evaluate classifier performance broken down by a grouping variable (e.g. customer segment, product line, pipeline version). It is ideal for lightweight, local evaluation against a naive-Bayes baseline without needing a hosted model or foundation model. Prefer it over general ML evaluation services when your task is specifically the four-class feedback theme schema (quality, price, delivery, support) and you need group-stratified metrics at minimal cost.

## Known failure modes

- More than 200 records submitted — request exceeds the bounded deliverable limit
- Missing required fields (id, text, actual, predicted, group) in any record — validation error
- Label values outside the enum (quality, price, delivery, support) — schema rejection
- Empty records array — no evaluation can be performed
- Malformed JSON body — request parsing failure

## How this service works

Feedback theme - Supplied-group evaluation: Supplied-group evaluation for Feedback theme. 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 supplied-group evaluation deliverable.

## Output

Returns per-group classification evaluation metrics for feedback themes (quality, price, delivery, support), including accuracy and naive-Bayes baseline comparisons across the supplied group segments, for up to 200 labelled text records.
