YieldSignal WETH Base Lending APY
x402
YieldSignal WETH Base Lending APY is a paid API for AI agents from yieldsignal.vercel.app, paid per call via x402, $0.1/call, status unknown (last checked 2026-10-30).
Returns real-time risk-weighted WETH lending APY across major Base DeFi protocols (Aave, Compound, Morpho, Moonwell, Euler, Fluid) with source attribution and EIP-712 signed response.

How this service works
Real-time risk-weighted WETH lending APY on Base: Aave/Compound/Morpho read onchain, Moonwell/Euler/Fluid via DefiLlama, source tagged per reading (never estimated). EIP-712 signed by the payment-receiving address (see X-Signal-* headers), which also holds an ERC-8004 identity and attests readings on-chain via EAS. Verified per-asset accuracy is free at /accuracy.json; raw on-chain attestations at /track-record.
Output
A JSON payload containing risk-weighted WETH lending APYs for each supported Base protocol (Aave, Compound, Morpho, Moonwell, Euler, Fluid), each tagged with its data source (onchain or DefiLlama). Response headers include EIP-712 typed data signature (X-Signal-Signature), signer address (X-Signal-Signer), and raw EIP-712 payload (X-Signal-Eip712-Payload) for cryptographic verification.
Example use cases
Example prompt
“What's the best risk-weighted APY I can get lending WETH on Base right now — show me rates from Aave, Compound, Morpho, Moonwell, Euler, and Fluid with which source each reading came from?”
Technical details
Endpoint
GEThttps://yieldsignal.vercel.app/signal/weth-base-yield?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need real-time, cryptographically signed WETH lending APY data across multiple Base DeFi protocols in a single call, with per-protocol source attribution proving estimates were never used. Prefer over manual protocol checks or generic DeFi aggregators when auditability, signing provenance, and risk-weighted comparison across 6+ protocols is required.
Side effects
- Onchain RPC unavailable — may return partial results or error for Aave/Compound/Morpho reads
- DefiLlama API unavailable — may return partial results or error for Moonwell/Euler/Fluid
- Payment not processed — 402 response requiring x402 USDC payment before data is returned
- Invalid or missing payment header — request rejected
- Protocol temporarily paused or data stale — source tag may indicate staleness
