## 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-aws-s3-33e16046
```

Example prompt: Can you check if shopify.com uses Amazon S3 — I want to know if they're hosting on it and see what evidence was found on their homepage?

## When to prefer this

Choose this endpoint when you need a fast, low-cost ($0.01) single-domain check specifically for Amazon S3 detection. It is ideal for enriching CRM records, qualifying sales leads, or conducting spot-checks during competitor research. Prefer it over broader technographic platforms when you only need S3 detection without subscribing to a full data service. Use the sibling bulk endpoint if checking more than a few domains at once.

## Known failure modes

- Domain not reachable or returns non-200 response — detection may be inconclusive
- Site uses heavy JavaScript rendering so static HTML fingerprints are not visible
- S3 usage is indirect (e.g. via CDN) and not exposed in homepage HTML or headers — may return false negative
- Invalid or malformed domain input — request fails or returns error
- Rate limiting or bot-blocking by target site prevents page fetch

## How this service works

Does a website use Amazon S3? Fetches the page (homepage for a bare domain) and matches Amazon S3's fingerprints in the HTML and response headers, returning yes/no with the evidence snippet and the category (hosting). Technographics for sales, competitor research and migration planning, one technology per call. $0.01 per check.

## Output

Returns a yes/no boolean indicating whether the target website uses Amazon S3, along with an evidence snippet (e.g. matching HTML patterns or response header values) and a category label (hosting).
