# Support Intent Fixed-Holdout Learning Curve

> Support Intent Fixed-Holdout Learning Curve 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).

Generates a fixed-holdout learning curve for a naive-Bayes support intent classifier (billing/technical/account/other) using up to 200 labelled text records.

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 support-intent-fixed-holdout-learning-curve-05e2283e -d '<json body>'
```

Example prompt: Run a fixed-holdout learning curve on my 150 labelled support tickets — each has an ID, the ticket text, and a category of billing, technical, account, or other — and show me how accuracy changes as training size grows.

## When to prefer this

Choose this endpoint when you need a quick, cheap diagnostic on whether a small labelled support-intent dataset is learnable and how much data is needed — without deploying a hosted or foundation model. Ideal for dataset sizing experiments, label quality checks, and naive-Bayes baselines on support ticket classification with up to 200 examples.

## Known failure modes

- Fewer than 2 records supplied (minItems violation)
- More than 200 records supplied (maxItems violation)
- Record text exceeds 1000 characters
- Record ID missing or empty
- Invalid 'actual' label outside enum (billing/technical/account/other)
- Insufficient class diversity for holdout split
- Payment of 0.01 USDC not processed via x402 protocol

## How this service works

Support intent - Fixed-holdout learning curve: Fixed-holdout learning curve for Support 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 fixed-holdout learning curve deliverable.

## Output

A fixed-holdout learning curve report showing classifier accuracy (or related metrics) at successive training set sizes, computed using a local naive-Bayes baseline on the supplied labelled records, with a fixed holdout split for consistent evaluation across training increments.
