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-64030cc3
```

Example prompt: Can you run an on-chain risk check on the wallet address 0x3f5CE5FBFe3E9af3971dD833D26bA9b5C936f0bE and tell me if it's flagged for anything suspicious?

## When to prefer this

Choose this endpoint when you need fast, automated on-chain risk scoring for a specific blockchain address prior to a transaction, counterparty interaction, or DeFi operation. It is especially useful for agents conducting pre-flight checks on wallet addresses, screening smart contracts, or building risk-aware transaction workflows where a $0.02 per-call micropayment via x402/USDC is acceptable.

## Known failure modes

- Missing or invalid address parameter returns an error
- Unsupported address format (non-EVM chains) may return empty or error data
- Rate limiting or payment failure via x402 results in HTTP 402
- Unknown or unindexed address may return empty risk data with status ok
- Network timeouts for addresses with extensive on-chain history

## 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

A JSON response containing on-chain risk data for the queried address, including a status field, a data object with risk signals and threat indicators, and an roi_proof field showing compression efficiency metrics.
