## 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 x402-apis-due-diligence-screening-b6668d63
```

Example prompt: Can you run a due diligence check on Acme Corp using the domain acmecorp.com? I want to know if there are any red flags before we sign a partnership agreement.

## When to prefer this

Use this endpoint when you need instant, no-account due diligence or company screening and are willing to pay per request via x402 micropayment. Ideal for AI agents that need to autonomously screen companies or domains without API key setup, especially in agentic workflows where per-call payment is acceptable.

## Known failure modes

- Domain or company not found — returns empty or minimal result
- Payment not completed or x402 protocol error — returns 402 Payment Required
- Invalid input schema — missing both domain and company fields returns error
- Unknown domain with no data — may return sparse or null result fields
- Rate limiting or server error — returns 5xx response
