# Cambrian x402 API – Euler Lending Markets

> Cambrian x402 API – Euler Lending Markets is a paid API for AI agents from x402.cambrian.org, paid per call via x402, $0.05/call, status unknown (last checked 2026-09-15).

Fetches Euler protocol lending market data (pools, rates, liquidity) on EVM chains via a pay-per-use x402 endpoint.

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-api-euler-lending-markets-21b92979
```

Example prompt: What are all the current lending markets on Euler Finance — I want to see the available pools, their borrow and supply rates, and liquidity levels?

## When to prefer this

Choose this endpoint when you need structured, on-demand Euler Finance lending market data for EVM chains without running your own indexer. Ideal for autonomous agents that need current DeFi lending rates, pool liquidity, or market listings and are willing to pay $0.05 USDC per query via the x402 protocol.

## Known failure modes

- Invalid or unsupported query parameters return an empty array or error
- Payment failure (insufficient USDC balance) results in HTTP 402 rejection
- Network or chain data unavailability may return stale or partial results
- Rate limiting if the x402 payment is not properly processed

## How this service works

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

## Output

Returns an array of Euler lending market objects, each containing market identifiers, supported tokens, supply and borrow interest rates, liquidity figures, and other pool-level metadata available from the Euler protocol on EVM chains.
