## 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 rwa-asset-due-diligence-fce42cef -d '<json body>'
```

Example prompt: Can you run a full due diligence check on this RWA issuer — covering their contracts, custody setup, and legal documents — and give me an evidence-backed report before I consider investing?

## When to prefer this

Choose this endpoint when you need structured, evidence-backed due diligence specifically covering the four pillars of RWA investment safety: issuer credibility, smart contract integrity, custody arrangements, and legal documentation. Prefer this over generic web search or document summarization when you need a consolidated, audit-ready report tied to on-chain and off-chain evidence for tokenized real-world assets.

## Known failure modes

- Insufficient input data about the issuer or asset returns incomplete coverage
- Unrecognized or unverifiable contract addresses result in partial contract findings
- Legal documents in unsupported formats or languages may not be fully analyzed
- Missing custody details lead to gaps in custody assessment section
- Network or data-source unavailability may cause stale or absent evidence links

## How this service works

Evidence-backed issuer, contract, custody and legal-document coverage

## Output

An evidence-backed due diligence report covering issuer credibility, smart contract assessment, custody arrangements, and legal document review for the specified real-world asset, with supporting evidence references for each finding.
