Euler Finance APYs API

Base and intrinsic APY surfaces. In v3, APY families are split into dedicated endpoints instead of being embedded inconsistently across larger payloads.

Operations 3

GET /v3/evk/vaults/{chainId}/{address}/apy Vault APY (current + historical) #
GET /v3/apys/intrinsic Intrinsic APYs #
GET /v3/apys/intrinsic/history Intrinsic APY history #
