How this service works
Call before qualifying a company website for web or marketing services. Returns its stack, builder, footer agency credit, observed marketing tags, LocalBusiness details and website quality signals, with evidence and a 0-100 improvement opportunity score. Reads the homepage and up to two linked internal pages. No contact values, rendering or outreach. Unknowns are explicit.
Output
Returns a structured lead profile including: detected technology stack with confidence evidence, identified CMS or site builder, any footer agency credit, list of observed marketing/analytics tags, LocalBusiness structured data details, website quality signals, and a 0-100 improvement opportunity score. Unknowns are explicitly stated rather than omitted. Coverage spans the homepage and up to two linked internal pages.
Example use cases
Pre-pitch website qualification for agency
“Before I reach out to this local accounting firm at https://www.muster-steuerberater.de, can you pull their full tech profile — what they're built on, what marketing tools they have, whether there's an agency name in the footer, and what their improvement opportunity score looks like?”
Competitor agency credit discovery
“I want to know who built the website at https://www.bäckerei-hofmann.de — check if there's an agency credit in the footer or anywhere on the site, and tell me what stack they're running.”
Website quality signal check before sales call
“I have a sales call tomorrow with the people behind https://www.stadthotel-berlin.de — can you analyze their site and tell me what tech they use, what marketing tags are active, and give me a quality and opportunity score so I know where to focus my pitch?”

Endpoint
POSThttps://stack.netzhandwerker.de/lead-profile?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a fast, structured pre-qualification profile of a single company website before pitching web design, SEO, or marketing services. It is purpose-built for agency lead qualification, returning tech stack, builder, agency credits, marketing tags, LocalBusiness metadata, quality signals, and an actionable improvement opportunity score — all with explicit unknowns. Prefer it over generic scraping tools when you need sales-relevant signals rather than raw HTML, and over contact-finding tools when the goal is technology and quality intelligence rather than outreach data.
Side effects
- URL is unreachable or returns non-200 status — profile may be empty or partial
- Website uses heavy JavaScript rendering — stack detection may miss client-side-only tools
- No footer agency credit found — field returned as explicit unknown
- Website blocks crawlers — may return minimal or no data
- Malformed or non-URI input — request rejected with validation error
- Private or intranet URLs — no public page accessible to crawl
