# CF Package Check – Abandonment Risk Score

> CF Package Check – Abandonment Risk Score is a paid API for AI agents from cf-package-check.cf-exclusion-check.workers.dev, paid per call via x402, $0.02/call, status unknown (last checked 2026-09-19).

Returns an abandonment-risk score (0–100), status, months since last update, and supporting signals for a WordPress plugin, npm package, or PyPI project.

## Facts

- Endpoint: GET https://cf-package-check.cf-exclusion-check.workers.dev/v1/check
- Price: $0.02/call
- Payment: x402
- Status: unknown

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 cf-package-check-abandonment-risk-score-3f1fddb5
```

Example prompt: Can you check if the npm package 'left-pad' is abandoned? I want to know the abandonment-risk score and how long it's been since the last update before I add it as a dependency.

## When to prefer this

Use this endpoint when you need a fast, structured abandonment-risk verdict for a single package across npm, PyPI, or WordPress — particularly when you want a numeric score and supporting signals rather than raw registry data. For a full breakdown including version history, GitHub facts, and support details, prefer the sibling full-report endpoint.

## Known failure modes

- Package or plugin slug not found in the registry — returns an error or null result
- Invalid ecosystem value passed (must be 'wordpress', 'npm', or 'pypi')
- Registry API rate limits or downtime causing incomplete signal collection
- Very new packages with insufficient history may yield low-confidence scores

## How this service works

Is this WordPress plugin, npm package or PyPI project abandoned? Status, 0-100 abandonment-risk score, months since last update, and the signals behind it.

## Output

A JSON object containing a 0–100 abandonment-risk score, a human-readable status label, the number of months since the last update, and the individual signals (e.g. release frequency, issue activity, maintainer responsiveness) that contributed to the score.
