# risk.yo.xyz Single Node Risk Grade Lookup

> risk.yo.xyz Single 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 2026-09-14).

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

## 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-single-node-risk-grade-lookup-5dd551ec
```

Example prompt: What's the risk grade and properties for Ethereum pool 0xbc99de6a88904cd0e69042ad6f266e63182801f030c636507c3caf590ffd84fe — give me the tier (A–F) and any breakdown of what's driving the score.

## When to prefer this

Use this endpoint when you need a fast, single-node risk tier lookup for a known DeFi pool or asset with a stable node ID (e.g. pool:ethereum:0x…). Prefer this over the dependencies endpoint when you only need the node's own properties and risk grade without neighbor/edge data, minimizing cost per call at $0.05 USDC.

## Known failure modes

- Invalid or malformed nodeId returns 404 or empty result
- Pool not indexed by risk.yo.xyz returns not found
- Payment not fulfilled (x402) returns 402 Payment Required
- Network or upstream graph database error returns 500
- Stale data if lastUpdatedAt is old — risk grade may not reflect current on-chain state

## How this service works

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

## Output

Returns a node object with a stable ID, PascalCase labels (e.g. Pool, Asset, Protocol, Chain), and a properties bag including _riskTier (letter grade A–F), tvlUsd (TVL in USD), riskBreakdown (array of {question, answer} pairs explaining the grade), and lastUpdatedAt timestamp.
