# AgentDiet Risk Assessment Node

> AgentDiet Risk Assessment Node is a paid API for AI agents from rag-diet.agentdiet.dev, paid per call via x402, $0.01/call, status unknown (last checked 2026-10-22).

Returns a risk assessment for a given address using the AgentDiet RAG-diet intelligence node, settling payment in USDC on Base via x402.

## 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-risk-assessment-node-dd672552
```

Example prompt: Can you check the risk score for the address 0xAbc123... using AgentDiet's risk node and tell me if it's safe to transact with?

## When to prefer this

Choose this endpoint when you need a fast, deterministic risk score for a specific blockchain address and are operating within an x402/L402 micropayment-capable agent stack settling in USDC on Base. It is especially suited for agent pipelines that require on-chain address screening at $0.01 per call with verifiable compression proof.

## Known failure modes

- Missing or invalid address query parameter returns empty or error data object
- Payment not settled in USDC on Base causes 402 Payment Required response
- Malformed input object (missing required 'type' or 'method' fields) causes request rejection
- Unknown or unsupported address format may return empty risk data
- Network or node unavailability returns a non-ok status

## How this service works

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

## Output

Returns a JSON object with a 'status' field ('ok'), a 'data' object containing the risk assessment details for the queried address, and a 'roi_proof' object including a compression_ratio_pct value (e.g. 91.4%) confirming the distillation efficiency of the response.
