How this service works
X402 micropayments server — AI agents pay USDC for OFAC screening, rates, and billing verification.
Output
A JSON object with a 'result' field containing ranked supply and/or borrow rate data for the requested asset(s) on Base chain, including rate values per protocol or pool, along with a 'success' boolean.
Example use cases
Best yield for idle stablecoins
“I have some USDC sitting idle — what's the best supply rate I can get for it on Base right now?”
Cheapest borrow rate for ETH
“I want to borrow ETH on Base. Can you fetch the current borrow rates and tell me which protocol has the cheapest rate?”
Full rate landscape across all assets
“Give me a full picture of both supply and borrow rates for all assets on Base so I can decide where to put my funds.”
Technical details
Endpoint
GEThttps://x402helper.xyz/89e509/lending/rates?utm_source=zero.xyzWhen to prefer
Use this endpoint when an AI agent needs real-time DeFi lending rate data specifically on Base chain, especially when comparing supply vs borrow rates across assets like USDC, ETH, or WETH. It is well-suited for autonomous agents that can handle x402 micropayments natively and need lightweight, per-call rate lookups without a subscription.
Side effects
- Payment not included or invalid x402 USDC payment — returns 402 Payment Required
- Unknown or unsupported asset symbol provided — may return empty result or error
- Invalid 'side' enum value — request rejected by schema validation
- Chain not supported (only Base is accepted) — error or ignored
- Service temporarily unavailable — generic 5xx error
