# risk.yo.xyz DeFi Node Search

> risk.yo.xyz DeFi Node Search is a paid API for AI agents from risk.yo.xyz, paid per call via x402, $0.001/call, status unknown (last checked 2026-09-15).

Searches for DeFi protocol/asset/pool nodes by address or name, returning risk grades and graph metadata

## Facts

- Endpoint: GET https://risk.yo.xyz/api/v1/agent/search
- Price: $0.001/call
- Payment: x402
- Status: unknown
- Last checked: 2026-09-15

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-f1e7ca16
```

Example prompt: Search the DeFi risk graph for the Uniswap protocol — give me its risk tier, labels, and node properties, and filter to nodes with TVL above 1 million and a grade of A or B.

## When to prefer this

Use this endpoint as the entry point when you need to discover DeFi protocol, asset, pool, or chain nodes by name or on-chain address before traversing the risk graph. It is the only discovery path — use it before calling node-detail or dependency endpoints that require a nodeId. Prefer it when you need to filter by risk grade (A–F), TVL range, or node label type to narrow results upfront.

## Known failure modes

- Empty or wildcard query (*, %) returns an error — targeted lookup only required
- Query matches no nodes — empty nodes array returned
- Grade comparator syntax invalid — malformed filter rejected
- TVL comparator syntax invalid — request rejected
- Limit exceeds 10 — capped or rejected
- Asset address not found in graph — empty result
- Payment not included or insufficient — 402 payment required response

## How this service works

Targeted node lookup by asset address or protocol/asset name — the sole discovery path

## Output

Returns an array of up to 10 matching graph nodes, each containing a stable node ID, PascalCase labels (e.g. Pool, Asset, Protocol, Chain), and a property bag including the risk tier (_riskTier, A–F scale) and other per-label metadata. Empty queries and wildcards are rejected.
