# SYS84 Due Diligence Report

> SYS84 Due Diligence Report is a paid API for AI agents from api.sys84.org, paid per call via x402, $0.25/call, status unknown (last checked 2026-10-11).

Generates a receipt-backed, evidence-grounded risk intelligence report for an EVM wallet address or token contract on Base chain, returning a risk score, verdict, findings, and recommended controls.

Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently.

## 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 sys84-due-diligence-report-8f1bc8d1 -d '<json body>'
```

Example prompt: Can you run a due diligence check on the token contract 0xAbC123...def456 on Base and tell me the risk score, verdict, and any red flags I should know about?

## When to prefer this

Choose this endpoint when you need a structured, evidence-backed risk verdict on a Base chain wallet or token contract before taking action — especially when you need a machine-readable verdict enum and risk score suitable for automated agent decision-making. Prefer this over generic blockchain explorers when you need actionable findings (honeypot detection, admin control probes, blacklist flags) and recommended controls in a single call. Best for pre-trade checks, pre-listing audits, or wallet screening before DeFi interactions on Base.

## Known failure modes

- Unsupported chain provided (only Base is currently supported) — likely returns a 400 or validation error
- Invalid or malformed EVM address — likely returns a 400 bad request
- Unknown or very new contract with insufficient on-chain data — may return incomplete findings or low-confidence scores
- Network or upstream provider outage — may return 5xx errors
- Missing required target or target_type parameter — returns validation error
- Payment not included or failed — returns 402 Payment Required

## How this service works

Receipt-backed token, wallet, NFT and launch intelligence for humans and agents.

## Output

A JSON object containing: a plain-English executive summary, a machine-actionable verdict (proceed/proceed_with_limits/require_human_review/avoid), a numeric risk score from 0–100 (higher = riskier), a categorical risk level (low/medium/high/critical), an array of evidence-backed findings, an evidence object with underlying checks, an array of recommended controls, a persistent report_id, and a deterministic report_hash for auditability.
