# Cambrian x402 Euler v2 Lending Vaults

> Cambrian x402 Euler v2 Lending Vaults is a paid API for AI agents from x402.cambrian.org, paid per call via x402, $0.05/call, status unknown (last checked 2026-09-14).

Fetches a list of Euler v2 lending vaults on EVM chains, returning structured vault data for DeFi analysis and agent automation.

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 cambrian-x402-euler-v2-lending-vaults-141309f2
```

Example prompt: Can you pull up all the available Euler v2 lending vaults on EVM so I can see what pools are currently live and compare their configurations?

## When to prefer this

Choose this endpoint when you need a live, pay-per-use list of Euler v2 lending vaults on EVM chains without maintaining your own blockchain indexer. It is ideal for autonomous agents that need on-demand DeFi data with micropayment settlement via x402 rather than API key subscriptions.

## Known failure modes

- No vaults returned if Euler v2 has no indexed vaults for the queried chain
- Payment failure (402) if USDC payment of $0.05 is not attached or insufficient
- Invalid query parameters may return empty array or error
- Upstream indexer unavailable may result in 5xx error
- Rate limiting or network timeout on the Cambrian proxy layer

## How this service works

Pay-per-use blockchain and social data for autonomous agents.

## Output

An array of Euler v2 lending vault objects, each containing vault metadata such as vault addresses, supported assets, and configuration details relevant to EVM-based lending on the Euler protocol.
