## 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 does-site-use-aos-89a5fea4
```

Example prompt: Can you check if acme.com uses the AOS (Animate On Scroll) library on their website and show me the evidence snippet if it does?

## When to prefer this

Use this endpoint when you need a fast, inexpensive ($0.01) single-technology check specifically for AOS (Animate On Scroll) on a given website. Prefer it over full-stack technographic crawlers when you only need AOS detection and want to avoid paying for broader scans. It is ideal for sales qualification workflows, competitive research on a known list of domains, or auditing client sites before a migration away from AOS.

## Known failure modes

- Website is unreachable or returns a non-200 status, resulting in inability to perform the check
- Website blocks automated HTTP requests or uses bot protection, leading to inconclusive results
- AOS is loaded lazily or via a tag manager and not present in the initial HTML response, causing a false negative
- Domain does not have a publicly accessible homepage
- Rate limiting or timeout on the target site during fetch

## How this service works

Does a website use AOS? Fetches the page (homepage for a bare domain) and matches AOS's fingerprints in the HTML and response headers, returning yes/no with the evidence snippet and the category (library). Technographics for sales, competitor research and migration planning, one technology per call. $0.01 per check.

## Output

Returns a yes/no answer indicating whether the target website uses the AOS (Animate On Scroll) library, along with an evidence snippet extracted from the HTML or response headers that matched AOS's fingerprints, and the technology category label (library).
