## 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 halowerk-tempo-api-response-loaded-resources-count-check-b0b8eddb -d '<json body>'
```

Example prompt: Check how many resources are loaded in the API response for https://api.example.com/data and tell me if it's excessive.

## When to prefer this

Use this endpoint when you specifically need to count the number of HTTP requests (loaded resources) triggered by an API response object at a given URL, as part of a web performance audit. Prefer this over generic HTTP analyzers when you want structured, per-object performance findings in the Halowerk Tempo ecosystem, particularly alongside sibling checks for fonts, stylesheets, images, and iframes.

## Known failure modes

- Target URL is unreachable or returns a non-2xx status — endpoint may return an error or empty finding
- URL exceeds 2048-character limit — validation error returned
- Non-public or private IP addresses rejected
- CSS selector matches zero elements — first match used or error returned
- Rate limiting or payment failure if USDC balance is insufficient
