## 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-datadog-rum-d4197796
```

Example prompt: Can you check whether shopify.com uses Datadog RUM? I want to know if they have Datadog's real user monitoring installed on their site.

## When to prefer this

Use this endpoint when you need a lightweight, single-domain check specifically for Datadog RUM presence. It is ideal for point-in-time technographic lookups during sales prospecting, competitor research, or pre-migration audits. Prefer this over bulk endpoints when checking only one domain. Choose this when you need the evidence snippet (the actual matched content) rather than just a binary signal.

## Known failure modes

- Domain not reachable or returns non-200 status — check may return no result or an error
- Site uses heavy client-side rendering that defers Datadog RUM injection — may produce a false negative
- Datadog RUM loaded via a custom proxy or obfuscated bundle — fingerprint may not match
- Rate limiting or bot protection on the target site — fetch may be blocked
- Invalid or malformed domain input — endpoint returns an error

## How this service works

Does a website use Datadog RUM? Fetches the page (homepage for a bare domain) and matches Datadog RUM's fingerprints in the HTML and response headers, returning yes/no with the evidence snippet and the category (monitoring). 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 Datadog RUM, along with the evidence snippet from the HTML or response headers that triggered the match, and the technology category label (monitoring).
