Tools

13 tools
check_badge
Check the SaaSCity badge
Check whether the SaaSCity badge is live on a site. Reads the given URL and, for a deep page, the site homepage too, rendering JavaScript if the static HTML misses it. A verified badge turns the listing link dofollow.
Read only Open world Idempotent
Input schema 
{'type': 'object', 'required': ['url'], 'properties': {'url': {'type': 'string', 'description': 'Site URL to scan (the listing URL; the homepage is read as well)'}}}
Output schema 
{'type': 'object', 'required': ['found', 'code', 'message'], 'properties': {'code': {'type': 'string', 'description': 'FOUND, BADGE_NOT_FOUND, UNREACHABLE, TIMEOUT, HTTP_ERROR, ...'}, 'found': {'type': 'boolean'}, 'message': {'type': 'string'}, 'badgeSnippet': {'type': 'string', 'description': 'The HTML to embed when not found'}}}
check_launch_readiness
Check launch readiness
Audit a product homepage before launching it: HTTPS, noindex, title and meta description, og:image (fetched to confirm it loads), X card, favicon, canonical, mobile viewport, h1, JSON-LD, robots.txt, sitemap, parked or 404 pages, response time, and whether the page is empty without JavaScript. Returns a 0-100 score, a verdict and a fix for every problem. Reads the static HTML the way directory scrapers and link-preview bots do.
