## 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 tech-detect-single-url-lead-profile-e8248e17 -d '<json body>'
```

Example prompt: Check out https://www.acmeplumbing.de and give me a tech stack breakdown — what CMS or builder they're using, what marketing tags are firing, who built it if there's a footer credit, any LocalBusiness info, and how high they score on the improvement opportunity scale so I can decide if they're worth pitching web services to.

## When to prefer this

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.

## Known failure modes

- 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

## 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.
