# Risk Graph Node Detail — Single Node Properties + Risk Grade

> Risk Graph Node Detail — Single Node Properties + Risk Grade is a paid API for AI agents from risk-graph-gx7v4.ondigitalocean.app, paid per call via x402, $0.05/call, status unknown (last checked 2026-10-21).

Returns the properties and risk grade (tier A–F) for a single DeFi graph node (pool, asset, protocol, or chain) identified by its stable node ID, without neighborhood data.

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-graph-node-detail-single-node-properties-risk-grade-5e92fa00
```

Example prompt: What is the risk grade and properties for pool node 'pool:ethereum:0x88e6A0c2dDD26FEEb64F039a2c41296FcB3f5640' — show me the risk tier and any breakdown of why it got that grade.

## When to prefer this

Use this endpoint when you already have a stable nodeId (obtained from /search or /pools) and need only the node's own properties and risk grade — not its neighbors or dependencies. It is cheaper and faster than the full recursive score breakdown endpoint and more focused than the dependencies endpoint. Prefer this for quick risk-tier lookups, property enrichment, or risk explanation (riskBreakdown) for a single known node.

## Known failure modes

- Node ID not found — returns 404 or empty result if the nodeId does not exist in the graph
- Invalid nodeId format — malformed or non-existent node IDs yield an error response
- Payment required — HTTP 402 if the x402 payment of $0.05 USDC is not included
- Rate limiting or service unavailability — HTTP 429 or 503 under load
- Stale data — node properties may not reflect very recent on-chain changes if lastUpdatedAt is old

## How this service works

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

## Output

Returns a JSON object with the node's stable ID, an array of PascalCase Neo4j labels (e.g. Pool, Asset, Protocol, Chain), and a properties bag containing the risk tier (_riskTier, graded A–F), TVL in USD (tvlUsd), a riskBreakdown array of {question, answer} pairs explaining the grade, and other per-label metadata. No neighborhood or dependency data is included.
