Technical details
Endpoint
GEThttps://baseyield-x402.vercel.app/v1/top-poolsWhen to prefer
Choose this endpoint when you need real-time, ranked DeFi yield data specifically on Base Mainnet (Chain ID 8453) and want per-call micropayment pricing via x402 rather than a subscription. Ideal for agents that need fresh APY snapshots on demand without committing to an API key or monthly plan.
Side effects
- Payment not received via x402 — returns 402 Payment Required before data is served
- Unknown or unsupported asset symbol — may return empty pool list or error
- min_tvl set too high — returns empty pools array if no pools exceed threshold
- Upstream on-chain data unavailability — stale or missing pool data
- Service downtime on Vercel hosting — 500 or timeout response
