# does-site-use-lodash

> does-site-use-lodash is a paid API for AI agents from site.intel.rallylive.ca, paid per call via x402, $0.01/call, status unknown (last checked 2026-10-02).

Checks whether a given website uses the Lodash JavaScript library by fetching its homepage and matching Lodash fingerprints in HTML and response headers.

Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently.

## 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-lodash-bc1125c9
```

Example prompt: Can you check if shopify.com uses Lodash? I need to know for my migration planning research.

## When to prefer this

Use this endpoint when you need a quick, cheap ($0.01) single-technology check specifically for Lodash on a given website. It is ideal for high-volume sales prospecting pipelines, competitor technographic research, or pre-migration audits where you need Lodash detection only. For bulk checks across many domains, the sibling bulk endpoint may be more efficient. For detecting other libraries, use the corresponding sibling endpoints.

## Known failure modes

- Site is unreachable or times out — no result returned
- Homepage returns non-200 status (e.g. 403, 503) blocking the fetch
- Lodash is loaded dynamically after page load (e.g. via lazy-loading) and not detected in static HTML
- Lodash is obfuscated or bundled under a non-standard filename, evading fingerprint matching
- Domain is invalid or malformed — request fails with input error

## How this service works

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

## Output

Returns a yes/no answer on whether the site uses Lodash, along with an evidence snippet (the matched fingerprint found in the HTML or response headers) and the category label 'library'.
