# risk.yo.xyz DeFi Pool Node Risk Grade Lookup

> risk.yo.xyz DeFi Pool 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 with breakdown) for a single DeFi pool node identified by a 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-defi-pool-node-risk-grade-lookup-6bba3377
```

Example prompt: What's the risk grade and breakdown for the Ethereum pool at 0xbeeff2c5bf38f90e3482a8b19f12e5a6d2fca757 — pull the A–F risk tier and any properties like TVL from risk.yo.xyz.

## When to prefer this

Use this endpoint when you need the risk grade and property details for a single known DeFi pool node (identified by its stable pool:chain:address ID) and do not need neighborhood or dependency graph data. Prefer this over the dependencies endpoint when you only need the node itself, not its upstream/downstream relationships.

## Known failure modes

- Invalid or malformed nodeId returns 404 or error response
- Unrecognized pool address not indexed in the graph returns empty or not-found response
- Payment not provided or insufficient USDC triggers 402 Payment Required
- Network timeout on slow graph queries
- Node exists but has stale or missing risk data

## How this service works

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

## Output

A JSON object with the node's stable ID, an array of PascalCase labels (e.g. Pool, Asset, Protocol, Chain), and a properties bag including _riskTier (letter grade A–F), tvlUsd (canonical USD size), and riskBreakdown (array of {question, answer} pairs explaining the grade) — no neighborhood data included.
