# Cambrian x402 Euler Curator Vaults

> Cambrian x402 Euler Curator Vaults is a paid API for AI agents from x402.cambrian.org, paid per call via x402, $0.05/call, status unknown (last checked 2026-09-12).

Returns a list of Euler protocol curator vaults on EVM-compatible blockchains via pay-per-use x402 micropayment.

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-curator-vaults-dd2a42bd
```

Example prompt: Can you pull the list of all curator vaults currently available on Euler Finance using the Cambrian x402 blockchain data API?

## When to prefer this

Use this endpoint when you need structured, on-demand data about Euler Finance curator vaults on EVM chains without running your own indexer. Ideal for agents that need pay-per-use blockchain data with micropayment via x402 rather than a subscription API key. Prefer this over manual RPC calls or subgraph queries when low-friction, agent-friendly access to Euler vault metadata is required.

## Known failure modes

- Missing or invalid query parameters may return an empty array
- x402 payment failure if USDC balance is insufficient, resulting in HTTP 402 response
- Upstream Euler protocol data unavailability may cause empty or error response
- Invalid chain/network context may yield no vault results
- Rate limiting or facilitator outage may block access

## How this service works

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

## Output

Returns an array of Euler curator vault objects, each containing vault metadata such as vault addresses, curator details, asset information, and protocol-specific configuration for Euler Finance on EVM chains.
