# Release Change Confidence Calibration Bins

> Release Change Confidence Calibration Bins is a paid API for AI agents from market.datapackvibe.com, paid per call via x402, $0.01/call, status unknown (last checked 2026-10-11).

Computes confidence calibration bins for a release-change classifier (feature/fix/documentation/maintenance) from up to 200 labelled text records with predicted probabilities.

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 release-change-confidence-calibration-bins-09a00e48 -d '<json body>'
```

Example prompt: I have 150 labelled release-change records — each has the actual label (feature, fix, documentation, or maintenance), the predicted label, and the 4-class probability vector from my classifier. Can you run confidence calibration bins on them so I can see how well the predicted probabilities match the true outcomes?

## When to prefer this

Choose this endpoint when you need calibration bin statistics specifically for a 4-class release-change classifier (feature/fix/documentation/maintenance) on small datasets up to 200 records, without needing a hosted model or foundation-model training. It is ideal for lightweight local evaluation workflows and post-hoc probability calibration audits on existing classifier outputs.

## Known failure modes

- More than 200 records submitted — input truncated or rejected
- Probability arrays not summing to 1 or containing values outside [0,1]
- Probability arrays with fewer or more than 4 elements — schema violation
- Invalid or missing class labels (must be one of: feature, fix, documentation, maintenance)
- Empty records array — no calibration computable
- Record IDs exceeding 80 characters or missing — validation error

## How this service works

Release change - Confidence calibration bins: Confidence calibration bins 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 confidence calibration bins deliverable.

## Output

Returns a bounded confidence calibration bins deliverable: binned statistics showing how well the classifier's predicted probabilities align with actual outcomes across the feature, fix, documentation, and maintenance classes, enabling assessment of model reliability and potential miscalibration.
