## 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 commerce-intent-multiclass-log-loss-calculator-1c4c430b -d '<json body>'
```

Example prompt: I have 150 labelled commerce intent records — each with the text, the actual label (browse, purchase, return, or other), the predicted label, and four class probabilities — can you compute the multiclass log loss so I can evaluate how well my classifier is doing?

## When to prefer this

Choose this endpoint when you need a quick, cheap ($0.01 USDC) multiclass log loss calculation for a commerce intent classifier with exactly four classes (browse, purchase, return, other), without needing to host a model or use a foundation model. Ideal for offline evaluation of small batches (up to 200 records) of labelled predictions from any classifier you already have.

## Known failure modes

- Probabilities array does not sum to 1 or contains values outside [0,1]
- More than 200 records supplied — exceeds maximum batch size
- Missing required fields (id, text, actual, predicted, probabilities) in any record
- Probabilities array has fewer or more than 4 elements
- Invalid enum value for actual or predicted class
- Payment not included or insufficient (0.01 USDC required)

## How this service works

Commerce intent - Multiclass log loss: Multiclass log loss for Commerce intent. 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 multiclass log loss deliverable.

## Output

Returns a bounded multiclass log loss value computed from the supplied labelled records, quantifying how well the predicted class probabilities align with the actual commerce intent labels (browse, purchase, return, other). Lower values indicate better probability calibration.
