## 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 kihustle-core-web-vitals-estimator-7039a92f -d '<json body>'
```

Example prompt: Can you estimate the Core Web Vitals for my landing page — here's the page text: 'Welcome to Morning Bloom Coffee, your neighborhood café in Brooklyn. Fast service, great espresso.'?

## When to prefer this

Use this endpoint when you need a quick, low-cost ($0.002) estimate of Core Web Vitals performance based on page text content, especially for SEO pre-checks or content audits within an automated workflow. Prefer it over full browser-based tools when you don't need pixel-accurate rendering measurements and want a fast programmatic signal integrated into an agent pipeline.

## Known failure modes

- Empty or missing 'text' field returns an error or undefined result
- Very long text inputs may time out or produce unreliable estimates
- Malformed JSON request body may return a 400-level error
- Service may return generic 'processed/success' even on edge-case inputs, making error detection difficult
- No detailed breakdown of individual vitals (LCP, CLS, FID) may be returned — only a summary status
