# Project Status Top-k Label Coverage

> Project Status Top-k Label Coverage is a paid API for AI agents from market.datapackvibe.com, paid per call via x402, $0.01/call, status unknown (last checked 2026-10-15).

Computes top-k label coverage metrics for a project status text classifier using up to 200 labelled 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 project-status-top-k-label-coverage-78cd7985 -d '<json body>'
```

Example prompt: Evaluate top-k label coverage for my project status classifier using these 50 labelled records — each has the actual label (planned, active, blocked, or complete), the predicted label, and the 4-class probability scores — and set k to 2 so we check if the correct label appears in the top 2 predictions.

## When to prefer this

Choose this endpoint when you need a quick, inexpensive top-k coverage evaluation for a project status text classifier with up to 200 records and no need for hosted model inference or foundation-model training. It is purpose-built for the four-class project status domain (planned, active, blocked, complete) and provides a single bounded metric deliverable at $0.01 per call, making it ideal for lightweight evaluation loops, CI/CD model checks, or comparing classifier variants on local datasets.

## Known failure modes

- More than 200 records submitted — exceeds the maximum allowed batch size
- Probabilities array does not contain exactly 4 values per record — schema validation failure
- k value outside 1–4 range — rejected by schema constraints
- Mismatched or invalid label values outside the allowed enum (planned, active, blocked, complete)
- Malformed record missing required fields (id, text, actual, predicted, probabilities)
- Payment failure or insufficient USDC balance for x402 protocol

## How this service works

Project status - Top-k label coverage: Top-k label coverage for Project status. 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 top-k label coverage deliverable.

## Output

Returns a bounded top-k label coverage deliverable: a metric indicating what fraction of records have the true label appearing among the top-k highest-probability predicted classes, computed across the supplied labelled text records for the project status domain (planned, active, blocked, complete).
