# YO Risk Graph

Risk Graph is YO's risk intelligence layer for DeFi. It scores pools, assets, protocols, and chains with a letter grade (A–F) based on their full dependency stack — not just the entity in isolation. This is the same system YO uses to inform vault allocations and due diligence.

Two ways to access it:

1. **Vault Exposure API** — free, public, no auth. Returns a vault's collateral exposure breakdown.
2. **Agent API** — paid via x402, for full risk grading and dependency mapping.

### Which one should I use?

<table><thead><tr><th width="158.546875"></th><th>Vault Exposure API</th><th>Agent API</th></tr></thead><tbody><tr><td>Cost</td><td>Free</td><td>Pay-per-query (x402/USDC)</td></tr><tr><td>Auth</td><td>None</td><td>Wallet signature</td></tr><tr><td>Returns</td><td>Collateral exposure for one vault</td><td>Risk grades, dependency graphs, entity search</td></tr><tr><td>Best for</td><td>Quick exposure checks, UX display</td><td>Full risk assessment, contagion analysis, agentic decision-making</td></tr></tbody></table>

Use the Vault Exposure API to see what a vault holds. Use the Agent API to grade what it holds and trace how risk propagates through it.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://docs.yo.xyz/yo-risk-graph.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
