## 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-due-diligence-dossier-a41ad481
```

Example prompt: Before I engage with 'Acme DeFi Labs' — I'm thinking of depositing $5k there — can you pull a full due diligence dossier on them as a DeFi project and tell me the risk verdict, score, and any red flags?

## When to prefer this

Use this endpoint when an AI agent needs a fast, machine-readable risk verdict on an entity, project, counterparty, domain, or wallet before taking an action (payment, onboarding, investment, contract) — especially when no API key setup is feasible and USDC micropayment authentication is preferred. Prefer over manual web research when you need a structured, signed, auditable verdict rather than raw search results.

## Known failure modes

- Target is too generic or ambiguous — service may return a dossier about the wrong entity sharing the same name (disclaimer included in response)
- Payment not received or x402 handshake fails — endpoint returns HTTP 402 and no dossier is produced
- Target entity has very little public web presence — confidence score will be low and signals sparse
- LLM synthesis may produce stale or incomplete data for obscure entities — check data_freshness.age_seconds
- Network timeout from Jina Reader during live web retrieval

## How this service works

Vet any company, crypto project, counterparty or domain before engaging: one call composes a risk DOSSIER — synthesis + detected signals + sources + 0-100 risk score + GO/CAUTION/STOP verdict + recommendation + a signed, offline-verifiable receipt. Is this entity a scam, fraud, sanctioned, or safe to deal with? Replaces 3-4 manual web searches plus the synthesis an agent would have to do itself, composed from live public web signals. Counterparty / vendor / project due-diligence for agents.

## Output

A structured JSON dossier including: CLEAR/CAUTION/HIGH_RISK verdict, numeric risk score (0-100), list of weighted risk signals (each with category, severity, and finding), source URLs, a human-readable summary, a recommendation, confidence score, data freshness metadata, and an Ed25519-signed receipt verifying the verdict — all returned as machine-readable JSON an agent can act on directly.
