## 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-paypal-d319cf18
```

Example prompt: Can you check if shopify.com uses PayPal on their site? I want to know if they have it integrated for payments.

## When to prefer this

Choose this endpoint when you need a cheap ($0.01), single-domain technographic signal specifically for PayPal presence. It is ideal for sales enrichment pipelines, competitive research, or migration audits where you need to quickly flag PayPal users at scale without running a full website audit. Prefer it over general-purpose web scrapers when you only need the PayPal yes/no answer and want a ready-made fingerprinting heuristic rather than writing your own detection logic.

## Known failure modes

- Domain is unreachable or returns non-200 status, resulting in an inconclusive or error response
- Site uses JavaScript-rendered PayPal integration that is not present in the raw HTML, causing a false negative
- Site actively blocks crawlers, returning a 403 or CAPTCHA page instead of real content
- Malformed or non-existent domain input causes a DNS resolution failure

## How this service works

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

## Output

Returns a yes/no flag indicating whether the site uses PayPal, along with the matching evidence snippet (e.g. the HTML fragment or header that triggered the fingerprint) and the technology category label ('payments').
