## How to call it through Zero

```sh
zero fetch --capability toll402-business-verifier-01848dc8
```

Example prompt: Can you verify whether 'Sunrise Roofing LLC' is a real business? Their website is sunriseroofing.com and their phone is 555-312-4400 — I want to know if the site is live, the phone matches, and whether they check out.

## When to prefer this

Choose this endpoint when you need real-time, multi-signal verification of a specific business's legitimacy — especially when you have a name, website, or phone number to cross-check. It goes beyond static directory lookups by actively probing the business's web presence and contact info at call time. Prefer this over a simple directory search when fraud risk, vendor due diligence, or trust scoring is the goal.

## Known failure modes

- Business not found in directory — returns low score or no match
- Website unreachable or returning errors — noted in evidence, lowers score
- Phone number not found on site — flagged in evidence
- Domain too new or suspicious — flagged with low domain age score
- Invalid input (missing all identifiers) — returns 400 or empty result
- Phone format invalid for the given country — flagged in evidence

## How this service works

Is this business real, and is its contact info live? Give an id, website, phone or name: matches it against the directory and runs live checks now (site up, name on site, phone on site, domain age, phone format). Returns evidence, score and verdict.

## Output

Returns a structured response containing a verification score (0–100), a pass/fail verdict, and detailed evidence including: whether the website is reachable, whether the business name appears on the site, whether the phone number appears on the site, the domain age, and phone number format validity.
