# risk.yo.xyz Pool Dependencies

> risk.yo.xyz Pool Dependencies is a paid API for AI agents from risk.yo.xyz, paid per call via x402, $1/call, status unknown (last checked 2026-09-15).

Returns the direct (1-hop) dependencies of a DeFi pool node, including neighboring nodes and typed edges describing relationships like collateralization, allocation, and backing.

## Facts

- Endpoint: GET https://risk.yo.xyz/api/v1/agent/dependencies
- Price: $1/call
- Payment: x402
- Status: unknown
- Last checked: 2026-09-15
- Activations on Zero: 0
- Tags: x402
- Canonical page: https://www.zero.xyz/c/risk-yo-xyz-839d1ea9
- Structured record (JSON): https://api.zero.xyz/v1/capabilities/cap_sTTmWgy1q3Q_Va2QmXlM1

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-839d1ea9
```

Example prompt: Can you pull the direct dependencies for pool node 'compound-v3-usdc-mainnet' — I want to see what assets, protocols, and chains it's immediately connected to and what kind of relationships link them?

## When to prefer this

Use this endpoint when you need to understand the immediate structural dependencies of a specific DeFi pool — which assets back it, which protocols interact with it, and the typed relationships between them. Prefer this over a full node lookup when neighborhood context and edge semantics matter, and over recursive traversal when only 1-hop neighbors are needed for risk assessment or dependency mapping.

## Known failure modes

- Missing or invalid nodeId returns a 400 or empty result
- nodeId not found in the graph returns empty neighbors/edges arrays
- Payment not included or insufficient USDC triggers a 402 Payment Required response
- Malformed query parameter causes schema validation error
- Node exists but has no dependencies returns empty arrays with valid 200

## How this service works

Direct (1-hop) dependencies of a pool — immediate neighbors + edge types

## Output

Returns a JSON object with two arrays: 'neighbors' (each with a stable node ID, PascalCase labels like Pool/Asset/Protocol/Chain, and a property bag including _riskTier rated A–F) and 'edges' (each with a type like ALLOCATES or IS_COLLATERALIZED_BY, sourceId, targetId, and additional properties). This gives a complete 1-hop neighborhood view of the pool's dependency structure.
