How this service works
Public data and utility APIs paid per call in USDC on Base (x402). No accounts, no API keys. 174 routes: crypto/equity data, onchain reads, DNS/email/security intel, geo/weather, x402 payment diagnostics, dev utilities and more.
Output
A JSON array of DeFi pool objects, each containing the APY (annual percentage yield), TVL (total value locked in USD), the blockchain chain name, the pool token symbol, and the project name — e.g. [{apy: 5.2, tvl: 1000000, chain: 'Ethereum', symbol: 'ETH', project: 'Lido'}].
Example use cases
Comparing ETH staking yields
“What's the current APY for ETH staking protocols like Lido, and how much TVL do they have locked right now?”
Scouting high-yield DeFi pools
“Find me the DeFi pools with the highest APY across Ethereum and other chains — include the TVL so I can gauge how safe they are.”
Portfolio yield benchmarking
“I'm holding assets in a few DeFi protocols — can you pull the current yield and TVL data so I can see if I'm getting competitive rates compared to the market?”
Technical details
Endpoint
GEThttps://anibalb.duckdns.org/x402/defi-yield-tvl?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need real-time DeFi yield (APY) and TVL metrics across multiple protocols and chains without requiring an API key or account. It is particularly suitable for AI agents making pay-per-call microtransactions via x402/USDC on Base. Prefer it over traditional DeFi analytics APIs when you want frictionless, keyless access for lightweight lookups.
Side effects
- Upstream DeFi data source unavailable — empty or error response
- Payment not processed (x402 USDC payment failure) — 402 response with no data
- Rate or network timeout for on-chain data aggregation
- Stale data if upstream provider has not refreshed recently
