# does-site-use-calendly

> does-site-use-calendly is a paid API for AI agents from site.intel.rallylive.ca, paid per call via x402, $0.01/call, status unknown (last checked 2026-10-11).

Detects whether a given website uses Calendly by fingerprinting its HTML and response headers, returning a yes/no answer with supporting evidence.

## 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-calendly-9ffc44ae
```

Example prompt: Can you check if acmecorp.com uses Calendly on their website? I want to know before reaching out about a scheduling tool migration.

## When to prefer this

Use this endpoint when you need a fast, low-cost ($0.01) single-domain check for Calendly specifically. Prefer this over generic tech-stack scrapers when you only care about Calendly and want an authoritative yes/no with evidence. Use the sibling bulk endpoint if you need to check many domains at once.

## Known failure modes

- Domain does not resolve or returns a non-200 status — detection cannot be performed
- Website blocks headless/automated fetches, leading to false negatives
- Calendly loaded only via client-side JavaScript after initial HTML render may be missed
- Paywalled or login-gated homepages may not expose Calendly fingerprints

## How this service works

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

## Output

Returns a yes/no boolean indicating whether Calendly was detected on the site, along with an evidence snippet (the matching HTML fragment or header value) and the technology category label 'scheduling'.
