How this service works
On-chain exchange rate of the main Ethereum liquid staking tokens (wstETH, rETH, cbETH, weETH, sfrxETH) against ETH, read from their contracts, with current APY from DefiLlama.
Output
A JSON array of liquid staking token objects, each containing: token symbol (e.g. wstETH), the base asset it denominates against (e.g. ETH or stETH), the on-chain exchange rate ('vale') indicating how many base asset units 1 token is worth, current APY percentage from DefiLlama, and the Ethereum contract address. Also includes a note explaining the 'vale' field and the data source.
Example use cases
Best LST yield comparison for investor
“I want to put some ETH into a liquid staking token — can you pull the current exchange rates and APYs for wstETH, rETH, cbETH, weETH, and sfrxETH so I can see which one is giving the best return right now?”
DeFi dashboard data feed for LSTs
“For my DeFi portfolio dashboard, fetch the latest on-chain exchange rates and current APY percentages for all major Ethereum liquid staking tokens.”
Arbitrage monitoring between LST rates
“Can you check the current on-chain rates of wstETH, rETH, and sfrxETH against ETH? I want to see if any of them are priced differently from what I'd expect given their APYs.”
Technical details
Endpoint
POSThttps://api.vextorium.com/staking-liquido-pago?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need authoritative, on-chain exchange rates for Ethereum liquid staking tokens (wstETH, rETH, cbETH, weETH, sfrxETH) rather than market prices, paired with DefiLlama APY — ideal for yield comparisons, portfolio valuation, or DeFi analytics dashboards where contract-level accuracy matters.
Side effects
- Ethereum RPC node unavailable — on-chain rate read fails
- DefiLlama API unavailable — APY data missing or null
- Network timeout reading from contract
- Stale data if block confirmation is delayed
