## 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-label-distribution-e9b7d153 -d '<json body>'
```

Example prompt: Can you check the label balance of my lead stage dataset? I have about 80 records labelled as enquiry, qualified, negotiation, or closed — here they are — and I want to see if the distribution is skewed before I train a classifier.

## When to prefer this

Choose this endpoint when you need a quick, cheap label distribution snapshot for a small lead-stage dataset (up to 200 records) without standing up your own analytics pipeline. It is ideal for pre-training data audits, evaluation set validation, or ad-hoc class balance checks on CRM exports — especially when you want a self-contained deliverable at minimal cost ($0.01 USDC).

## Known failure modes

- Fewer than 2 records submitted — minimum item count not met
- More than 200 records submitted — exceeds maximum item count
- Invalid or missing 'actual' enum value (must be one of: enquiry, qualified, negotiation, closed)
- Record text exceeds 1000 character limit
- Missing required fields (id, text, actual) on one or more records
- Payment of 0.01 USDC not fulfilled — x402 payment required

## How this service works

Lead stage - Label distribution: Label distribution 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 label distribution deliverable.

## Output

A bounded deliverable showing the count and proportion of records for each of the four lead stages (enquiry, qualified, negotiation, closed) across the supplied dataset of up to 200 labelled text records, highlighting class balance or skew.
