# Website Tech Stack

`POST /v1/tools/tech_stack`

## Request

- Base URL: `https://unstuckapi.com`
- URL: `https://unstuckapi.com/v1/tools/tech_stack`
- Auth: one of:
  - HTTP bearer
  - API key in header `x-api-key`

See what a website is built with: its store platform (Shopify, WooCommerce), CMS (WordPress), email marketing, analytics, payments, hosting and more, plus the phone numbers, emails and social profiles published on the site. Use it to qualify a sales lead, size up a competitor, or find out what software a company already pays for. Data comes from a regularly refreshed web crawl, not a live visit; last_checked says when the site was scanned, and small or new sites may show only part of their stack.

Price: $0.05 per call. Charged once per call that returns a result, including an empty result list. Failed calls are free.
