# AgentDiet On-Chain Risk Assessment

> AgentDiet On-Chain Risk Assessment is a paid API for AI agents from arxiv-digest.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, analyzing wallet or contract risk signals

## Facts

- Price: $0.02/call
- Payment: x402, MPP
- Status: unknown

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-b958fbf9
```

Example prompt: Can you run an on-chain risk check on the wallet address 0x3f5CE5FBFe3E9af3971dD833D26BA9b5C936f0bE and tell me if it looks safe or suspicious?

## When to prefer this

Choose this endpoint when you need a quick, agent-native on-chain risk score for a specific blockchain address and are willing to pay micro-fees per call via USDC (x402). Prefer it over manual block explorer lookups when you need programmatic, structured risk output. Best suited for DeFi agents, wallet screening workflows, or pre-transaction due diligence pipelines.

## Known failure modes

- Missing or invalid address query parameter returns an error or empty data
- Non-existent or unindexed blockchain address may return empty risk data
- Network-specific addresses may not be supported if chain is not indexed
- Payment failure via x402/HTTP 402 if USDC balance is insufficient
- Rate limiting or timeout if the on-chain data source is slow

## 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 'data' field containing on-chain risk signals and metrics for the queried address, a 'status' field indicating success, and a 'roi_proof' field showing compression efficiency (e.g. compression_ratio_pct: 91.4), summarizing the risk posture of the given blockchain address.
