How this service works
558 pay-per-call data APIs for AI agents: Solana and EVM on-chain data, tokenized stocks, DeFi, Hyperliquid, economy and official statistics, FX, validation, web and developer tools. Pay in USDC via x402.
Output
A JSON object listing each liquid staking token (e.g. wstETH, rETH, cbETH, weETH, sfrxETH) with: the base input asset (e.g. stETH or ETH), the number of base asset units each token is worth ('worth', reflecting accumulated staking rewards), the current APY as a percentage, and the Ethereum contract address. Also includes a source attribution note (Ethereum contracts + DefiLlama).
Example use cases
Best LST yield comparison for allocation
“I'm deciding where to stake my ETH — can you pull the latest APY and exchange rates for wstETH, rETH, cbETH, weETH, and sfrxETH so I can see which liquid staking token is giving the best return right now?”
Portfolio valuation of staked ETH holdings
“I hold some wstETH and rETH — can you fetch their current on-chain exchange rates against ETH so I can calculate exactly how much ETH my holdings are worth today?”
Daily DeFi staking rate monitoring
“Check today's APY and ETH exchange rates for all the major Ethereum liquid staking tokens and let me know if any of them have moved significantly compared to typical rates around 2-3%.”
Technical details
Endpoint
POSThttps://api.vextorium.com/v1/liquid-staking-rates?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need authoritative, on-chain exchange rates for Ethereum LSTs (wstETH, rETH, cbETH, weETH, sfrxETH) directly from their smart contracts, combined with live APY figures. Prefer this over DEX price feeds when you want the true redemption rate (not market price) and staking yield in a single call. Ideal for portfolio valuation, yield comparison, or any agent workflow needing LST fundamentals rather than spot trading prices.
Side effects
- Ethereum node or contract read failure may result in missing or null token data
- DefiLlama APY data may be temporarily unavailable, returning null apy_pct
- Payment not completed (x402 protocol) results in 402 response with no data
- Rate limiting or quota exhaustion for the $0.004/call micropayment API
- Stale data if on-chain contracts are congested or DefiLlama cache is delayed
