How this service works
Blockchain data APIs with x402 payments on Solana + Base via PayAI facilitator. 7 endpoints covering bridge routing, whale alerts, DeFi yields, RPC, NFT, token, and transaction history.
Output
A list of DeFi yield opportunities matching the filters, each including protocol name, chain, token, APY percentage, and risk level — up to the requested limit (max 50).
Example use cases
Stablecoin yield optimization
“What are the top 15 low-risk DeFi yields available for USDC right now across Ethereum, Base, and Arbitrum, with at least 4% APY?”
High-APY opportunity scouting
“Show me up to 20 DeFi protocols on Solana offering more than 15% APY — I'm okay with medium or high risk.”
Cross-chain ETH yield comparison
“Compare the best DeFi yield options for ETH across all supported chains, limit to 10 results, with medium risk at most.”

Endpoint
POSThttps://solana-x402-xi.vercel.app/api/v1/defi-yields?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need real-time DeFi yield data filterable by chain, token, APY floor, and risk tolerance — especially useful for agents optimizing capital allocation or scanning for yield opportunities across Solana, Base, Ethereum, and Arbitrum with micropayment-based access.
Side effects
- Invalid chain name returns empty results or 400 error
- minAPY higher than any available yield returns empty list
- limit out of range (>50 or <1) may return validation error
- maxRisk value not in allowed enum (low/medium/high) causes rejection
- Payment not completed via x402 returns 402 Payment Required
