## 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 business-verification-machine-b3e730a2
```

Example prompt: Can you verify whether 'Sunrise Plumbing LLC' is a legitimately registered business in New York — also check if their website sunriseplumbing.com is live and if phone 212-555-0198 looks valid?

## When to prefer this

Choose this endpoint when you need a fast, lightweight business legitimacy snapshot combining state registry lookup with supplemental signal checks (website, phone, address) for any of the five supported states. It is ideal for pre-contract due diligence, vendor onboarding screening, or marketplace seller vetting where a full credit report or legal investigation is not needed. Prefer alternatives if you need coverage beyond NY/CO/PA/OR/CT, financial credit data, UCC filings, or legal judgment history.

## Known failure modes

- State not supported — only NY, CO, PA, OR, CT are covered; unsupported state returns error or NOT_FOUND
- Business name not found in selected state registry — returns NOT_FOUND verdict
- Website liveness check may time out if site is slow — flagged accordingly
- Phone or address validation may be inconclusive if format is non-standard
- Render cold-start latency may cause occasional timeout on first request
- Missing required 'name' or 'state' query parameters returns validation error

## How this service works

Business verification snapshot: state-registry status (NY/CO/PA/OR/CT), website-alive, address validation, phone plausibility -> verdict + confidence + flags. Not a credit report.

## Output

Returns a verdict (VERIFIED, PARTIAL, UNVERIFIED, or NOT_FOUND), an integer confidence score (0–100 or null), an array of flags describing issues found, an array of individual check results (state registry, website liveness, address validation, phone plausibility), and a coverage note explaining any limitations of the check.
