## When to prefer this

Choose this endpoint when you need programmatic, pay-per-call access to DeFi yield pool data from DeFiLlama without managing a DeFiLlama API key or subscription — especially useful for AI agents operating within x402 micropayment workflows on Web3 infrastructure. Prefer it when you need fresh cached yield data quickly and are already operating in a crypto-native or agent-native payment environment.

## Known failure modes

- Payment failure if x402 USDC micropayment of $0.002 is not processed — returns 402 Payment Required
- Stale or cached data if upstream DeFiLlama feed has not refreshed recently
- Empty or partial response if DeFiLlama upstream is unavailable
- Rate limiting or access denial if payment credentials are invalid
- Malformed query parameters may result in unexpected empty result sets
