# Liquid Staking Tokens Comparison API > The major Ethereum liquid-staking tokens (LSTs) compared side by side, read keyless directly from the Ethereum blockchain via a public RPC node. When you stake ETH through Lido, Rocket Pool, Coinbase, Binance or Frax you receive a liquid-staking token — wstETH, rETH, cbETH, wBETH or sfrxETH — whose on-chain exchange rate against ETH climbs as staking rewards accrue. Those rates, and the yields implied by how fast they climb, differ between providers, and that spread is exactly what someone choosing where to stake (or arbitraging between LSTs) needs in one place. The rates endpoint is the comparison table: every tracked LST with its live ETH exchange rate, its net staking APR over the last week (derived from the on-chain rate growth), its token supply and its issuer, ranked by yield. The token endpoint drills into one LST by symbol — its rate, supply, ETH backing (TVL) and the APR over the last day, week and month. The convert endpoint converts any amount between any LST and ETH, or between two LSTs, at the current on-chain rates. This is the cross-LST comparison cut — distinct from the single-protocol feeds (lido, Rocket Pool, ether.fi) and the DeFi-TVL feeds: it is about the exchange rates and on-chain-derived yields of the staking tokens themselves. Every number is read live from each token contract; APR is derived from real historical on-chain state, not a marketing figure. Rates are ETH per token. Keyless, nothing stored beyond a short cache. ## Authentication All requests require your oanor API key in the `x-oanor-key` header.
