# AgentDiet On-Chain Risk Assessment

> AgentDiet On-Chain Risk Assessment is a paid API for AI agents from prompt-guard.agentdiet.dev, paid per call via x402 or MPP, $0.02/call, status unknown (last checked 2026-10-20).

Returns on-chain risk intelligence for a given blockchain address, scoring wallets or contracts for suspicious activity, exposure, and threat signals.

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 agentdiet-on-chain-risk-assessment-3bf38ab4
```

Example prompt: Can you check whether the Ethereum address 0x742d35Cc6634C0532925a3b8D4C9C6 is risky to interact with — I want to know if it's been flagged for fraud, sanctions, or suspicious on-chain behavior before I send anything there.

## When to prefer this

Use this endpoint when you need fast, per-address on-chain risk scoring for wallet or contract due diligence, especially in DeFi, crypto payments, or compliance workflows. Prefer this over generic blockchain explorers when you need structured risk signals rather than raw transaction history. Best suited for agent-driven screening workflows where a pay-per-call model ($0.02 USDC via x402) is acceptable and real-time risk assessment is needed.

## Known failure modes

- Missing or invalid address parameter returns an error or empty data object
- Address not found on supported chains returns empty or null risk data
- Malformed address string may result in a validation error
- Payment not provided or insufficient USDC balance triggers HTTP 402
- Rate limiting or quota exceeded returns an error response
- Unsupported blockchain network may return no results

## How this service works

15-App Autonomous Business-to-Agent (B2A) API Hub & MCP Suite. Supports Web Distillation, On-Chain Risk, DEX Token Intelligence, B2B Lead Enrichment, Domain OSINT, Email Verification, SEC Filings, GitHub Audits, Prompt Firewall, and native HTTP 402 (x402 Base USDC).

## Output

Returns a JSON object with a status field, a data object containing on-chain risk intelligence (such as risk scores, flags, threat categories, and entity metadata for the queried address), and an roi_proof field showing compression or distillation efficiency metrics.
