## 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 buildpulse-contractor-vetting-guide-ba638e27
```

Example prompt: I'm about to hire a general contractor for a kitchen remodel in Austin, TX — can you pull up the interview questions I should ask, red flags to watch out for, contract terms I should insist on, and what market rates I should expect to pay?

## When to prefer this

Use this endpoint when a homeowner or renovation agent needs to prepare for contractor interviews and negotiations — specifically when the goal is risk reduction, due diligence, and contract protection rather than cost estimation or scheduling. Prefer this over cost-estimate endpoints when the primary concern is identifying trustworthy contractors, not project budgeting.

## Known failure modes

- Missing or unrecognized project type returns generic or empty guidance
- Unsupported geographic region may return no market rate data
- Overly vague project description yields low-specificity questions
- Payment failure (402) if x402 USDC payment is not completed
- Rate limiting or API downtime returns 5xx error
