How this service works
Lido stETH vs ETH peg from public USD prices (DefiLlama coins API): stETH and ETH price, discount or premium in %, plus Lido's total stETH staked and market cap. The two prices can be quoted a few minutes apart. Curve pool balances and the Lido withdrawal queue are not included.
Output
Returns a JSON object with ETH USD price, stETH USD price, the peg percentage (stETH vs ETH as a % difference), total stETH staked, stETH market cap in USD, the timestamp of the check, and the Unix timestamps of when each price was quoted. Sourced from DefiLlama's price feed.
Example use cases
DeFi peg depeg alert monitoring
“Check if Lido stETH is significantly off peg right now — if it's more than 0.5% below ETH price, let me know immediately.”
Liquid staking portfolio valuation
“I hold stETH — what is the current stETH price in USD and how does it compare to ETH right now so I can value my position accurately?”
Lido protocol health dashboard
“Pull the latest Lido stETH peg data for me — I want the peg percentage, total ETH staked, and the stETH market cap to update my DeFi dashboard.”
Technical details
Endpoint
GEThttps://api.chainmarket-api.workers.dev/api/crypto/lido-steth-peg?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a real-time, on-chain-sourced snapshot of the Lido stETH peg health, including both ETH and stETH USD prices and total protocol stake size, without any API key or signup. Prefer over manual DeFi aggregator queries when you need a single structured JSON response suitable for agent pipelines, alerting, or dashboard updates.
Side effects
- Upstream DefiLlama price feed unavailable — stale or missing price data
- Network error reaching coins.llama.fi — may return 5xx or empty response
- stETH or ETH contract address not found in upstream feed — missing fields in response
- Payment verification failure on x402 — call is not charged and returns 402
