## 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-addthis-ce7dc6e1
```

Example prompt: Can you check whether shopify.com uses AddThis for social sharing — I want to know if they have it installed and what evidence you found in the page?

## When to prefer this

Use this endpoint when you need a fast, cheap ($0.01) per-domain check specifically for AddThis presence. It is purpose-built for AddThis fingerprinting with pre-tuned patterns, making it more reliable and less expensive than running a generic technology scanner. Ideal for bulk sales prospecting pipelines, competitor technographic research, or pre-migration audits where you need a definitive AddThis yes/no signal without building your own scraper.

## Known failure modes

- Domain is unreachable or returns a non-200 status — detection may return no result or an error
- Single-page apps that render content client-side may not expose AddThis in the initial HTML fetch, leading to false negatives
- AddThis loaded via tag manager may not be fingerprinted if the script tag is injected post-load
- Rate limiting or bot-blocking on the target domain may prevent the page from being fetched
- Bare domain vs subdomain ambiguity — only the homepage is checked, not subpages

## How this service works

Does a website use AddThis? Fetches the page (homepage for a bare domain) and matches AddThis's fingerprints in the HTML and response headers, returning yes/no with the evidence snippet and the category (sharing). 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 website uses AddThis, along with the evidence snippet (the matching HTML or header content that triggered the fingerprint match) and the technology category label ('sharing').
