# Release Change Prediction Error Records

> Release Change Prediction Error Records is a paid API for AI agents from market.datapackvibe.com, paid per call via x402, $0.01/call, status unknown (last checked 2026-10-12).

Computes prediction error metrics for a labelled dataset of release-change text records classified into feature/fix/documentation/maintenance categories.

## 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 release-change-prediction-error-records-ebafcb1b -d '<json body>'
```

Example prompt: Evaluate the prediction errors for my release-change classifier — here are up to 200 labelled records, each with the text, the actual label (feature, fix, documentation, or maintenance), the predicted label, and the four class probabilities. Give me back the error records and metrics.

## When to prefer this

Choose this endpoint when you need lightweight, local evaluation of a release-change text classifier across the four categories (feature, fix, documentation, maintenance) without invoking a hosted or foundation model. Ideal for auditing small holdout sets (up to 200 records), running naive-Bayes baselines, or diagnosing misclassifications in a changelog/commit tagger pipeline at minimal cost ($0.01 per call).

## Known failure modes

- More than 200 records submitted — exceeds maximum batch size
- Missing required fields (id, text, actual, predicted, probabilities) on any record
- Probabilities array does not contain exactly 4 values or values outside [0,1]
- Invalid enum value for actual or predicted label (must be feature, fix, documentation, or maintenance)
- Empty records array submitted
- Payment not included or insufficient (requires 0.01 USDC via x402)

## How this service works

Release change - Prediction error records: Prediction error records for Release change. 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 prediction error records deliverable.

## Output

A bounded deliverable of prediction error records for the submitted release-change labelled dataset, including per-record error analysis and evaluation metrics (e.g. misclassification details, log-loss components) derived from actual vs predicted labels and class probabilities, using local dataset tools and naive-Bayes baselines.
