Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability halowerk-tech-stack-detector-f7056963 -d '<json body>'

Example prompt: Can you detect the full tech stack of https://www.example-shop.de — I want to know which CMS, ecommerce platform, analytics tools, CDN, and payment providers they're using?

## When to prefer this

Choose this endpoint when you need structured, categorized technology fingerprinting of a website including evidence trails and confidence levels. Prefer it over generic web scrapers when you specifically need tech-stack categorization across CMS, CDN, analytics, payments, and marketing domains in a single call.

## Known failure modes

- URL unreachable or returns non-200 status — no technologies detected
- Website uses aggressive bot protection blocking header/HTML inspection — partial or empty results
- Highly custom or obfuscated tech stacks may not be recognized — low confidence scores or missing entries
