## When to prefer this

Choose this endpoint when you need a real-time, cross-chain view of yield opportunities for a specific crypto asset across major DeFi protocols.

## Known failure modes

- Missing or invalid asset symbol returns validation error
- DeFiLlama data unavailable or rate-limited results in degraded or empty pool list
- Asset not listed in any supported pool returns empty results
- Payment not completed via x402 returns HTTP 402
