## When to prefer this

Choose this endpoint when you need structured, up-to-date Euler V2 lending vault market data on EVM chains and want to pay only per call via x402 micropayment without a subscription. Ideal for autonomous agents doing DeFi research, yield comparison, or monitoring Euler protocol markets programmatically.

## Known failure modes

- Payment failure if x402 USDC micropayment is not properly configured — returns 402 Payment Required
- No query parameters matched — may return empty array if filters are overly restrictive
- Upstream Euler V2 data unavailable — may return 503 or empty result if the data provider is down
- Invalid query parameters — may return 400 Bad Request or unexpected results
- Rate limiting or quota exceeded — returns 429 Too Many Requests
