## 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 agent-market-lab-website-due-diligence-1fb0d283 -d '<json body>'
```

Example prompt: Can you do a full due-diligence check on https://acme-supplies.com — I want to know their trust signals, contact details, and what tech stack they're running before we sign a contract with them?

## When to prefer this

Choose this endpoint when you need structured business intelligence about a public website — especially trust, contact, and technology signals — in a single pay-per-call request without managing scraping infrastructure. It is ideal for vendor due diligence, lead enrichment, and competitive research workflows where an autonomous agent needs actionable metadata rather than raw page HTML. Prefer it over generic scrapers when you specifically need trust scoring, contact extraction, and tech-stack detection combined in one response.

## Known failure modes

- Private hosts or IP literals are rejected with a validation error
- Non-existent or unreachable URLs return a fetch failure
- Sites behind login walls or CAPTCHAs may return incomplete data
- Payment failure via x402 results in 402 response before analysis runs
- Malformed or non-HTTP/HTTPS URLs are rejected at input validation
