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-onchain-risk-assessment-09610c16
```

Example prompt: Can you check the onchain risk for the wallet address 0x742d35Cc6634C0532925a3b8D4C9B7e1bF3d5A12 and tell me if it looks safe to interact with?

## When to prefer this

Choose this endpoint when you need a quick, pay-per-call onchain risk score for a blockchain address without setting up a full analytics subscription. It is especially useful in agentic workflows where an AI needs to autonomously assess wallet or contract risk before executing a transaction, settling in USDC on Base via x402.

## Known failure modes

- Missing or invalid 'address' query parameter returns empty or error data
- Invalid blockchain address format may return no meaningful risk data
- Payment failure (non-USDC or insufficient balance) results in 402 response
- Unsupported HTTP method returns schema validation error
- Network or gateway downtime returns 5xx error

## How this service works

Deterministic B2A/A2A/MCP/x402/MPP/L402 execution and intelligence node at https://mcp-gateway.agentdiet.dev settling in USDC on Base.

## Output

A JSON object with a 'status' field (e.g. 'ok'), a 'data' object containing risk metrics for the queried address, and an 'roi_proof' object including a compression_ratio_pct indicating how much intelligence was compressed into the response.
