# risk.yo.xyz Node Risk Grade Lookup

> risk.yo.xyz Node Risk Grade Lookup is a paid API for AI agents from risk.yo.xyz, paid per call via x402, $0.05/call, status unknown (last checked 2026-10-30).

Fetches properties and risk grade (tier A–F with breakdown) for a single DeFi node (pool, asset, protocol, or chain) by its stable node ID

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 risk-yo-xyz-node-risk-grade-lookup-30e8ec6e
```

Example prompt: What's the risk grade and breakdown for the Ethereum Uniswap USDC/ETH pool — give me the risk tier and any properties like TVL from risk.yo.xyz using node ID pool:ethereum:0x88e6a0c2ddd26feeb64f039a2c41296fcb3f5640.

## When to prefer this

Use this endpoint when you need risk grade and properties for a single, known DeFi node (pool, asset, protocol, or chain) and already have its stable nodeId from a prior search. Prefer this over the dependencies endpoint when you don't need the neighborhood graph — it's faster and cheaper. Use the /search endpoint first if you don't yet have the nodeId.

## Known failure modes

- Invalid or malformed nodeId returns a 404 or empty result
- nodeId not found in the graph returns an error or null response
- Payment failure (x402) if USDC payment of $0.05 is not properly attached
- Stale data if the node has not been recently indexed (check lastUpdatedAt)
- Rate limiting if too many requests are sent in quick succession

## How this service works

Single node — properties + risk grade only (no neighborhood)

## Output

Returns a JSON object with the stable node ID, an array of Neo4j PascalCase labels (e.g. Pool, Asset, Protocol, Chain), and a property bag including: `_riskTier` (letter grade A–F), `riskBreakdown` (array of {question, answer} objects explaining the grade in plain language), `tvlUsd` (total value locked in USD), and metadata fields. No neighborhood or dependency graph is included — just the single node.
