## When to prefer this

Use this endpoint when you need a quick cross-protocol yield comparison for a specific crypto asset without building your own DeFi data aggregation. Ideal for agents that help users optimize passive income on idle crypto holdings. Prefer this over manual protocol research when you need ranked, consolidated yield data in a single call paid per-use via USDC on Base.

## Known failure modes

- Unknown or unsupported asset symbol returns an error or empty results
- Asset with no tracked yield pools returns no results
- Payment failure via x402 protocol returns 402 Payment Required
- Rate limiting or service downtime on Vercel returns 5xx errors
- Stale yield data if protocols are not recently indexed
