## 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-adyen-fe0ee9e5
```

Example prompt: Can you check whether shopify.com uses Adyen as its payment processor and show me any evidence found on the page?

## When to prefer this

Use this endpoint when you need a fast, low-cost ($0.01) signal on whether a specific website is running Adyen, without building your own web-scraping and fingerprinting pipeline. It is ideal for sales teams prospecting for Adyen users, competitive analysts benchmarking payment stacks, or engineers doing pre/post-migration validation. Prefer this over generic technographic databases when you need a real-time, on-demand check against the live site rather than a cached dataset.

## Known failure modes

- Website is behind a bot-protection wall or CAPTCHA, preventing page fetch and returning no evidence
- Domain does not resolve or returns a non-200 status, causing the check to fail
- Adyen is loaded via a third-party tag manager or lazy-loaded JavaScript that isn't present in the initial HTML fetch, leading to a false negative
- Obfuscated or minified script references may not match fingerprints, yielding a false negative
- Rate limiting or network timeouts on the target site may cause inconclusive results

## How this service works

Does a website use Adyen? Fetches the page (homepage for a bare domain) and matches Adyen'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 answer indicating whether Adyen was detected on the target website, along with the specific evidence snippet (matching HTML or header fragment) that triggered the match, and the technology category label (payments).
