Response Data
data is an array; each element holds the statistics for one options expiration date: the max pain price for that expiration date, and the open interest, notional value and market value of call and put options. For example, with symbol=BTC and exchange=Deribit, 11 expiration dates are returned. max_pain_price is returned as a string; convert it to a number before doing calculations.
Notional Value and Market Value Are Not the Same
*_notionalis the notional value: for example, withsymbol=BTCandexchange=Deribit,call_open_interest_notional ÷ call_open_interestis about $82,000, close to the BTC price at the time; that is, it is the size of the open interest calculated at the price of the underlying.*_market_valueis the market value, calculated at the market price of the options themselves, and is usually far smaller than the notional value. Both are in USD.

FAQ
Which coins and exchanges are supported?
Currently only four coins, BTC, ETH, SOL and XRP, and four exchanges, Deribit, OKX, Binance and Bybit, are supported. Exchanges are matched exactly as strings, so pass them as written here; values outside this range return a not-supported message.
How do I parse date?
date is a string in YYMMDD format that represents the options expiration date, e.g., 261020 is 2026-10-20 and 261021 is 2026-10-21.
Why is max_pain_price a string?
The endpoint returns the strike price as a string, e.g., "82000". Convert it to a number before using it in calculations or comparing values.
Is this the same as liquidation max pain?
No. This endpoint calculates it from the open interest structure of options; Liquidation Max Pain is based on the futures liquidation model, and the two differ in how they are calculated and in what they mean.
Learn More: Options Max Pain
What Is Options Max Pain?
Max pain is the strike price at which, for a given expiration date, the total intrinsic value of all open options would be smallest if the underlying price finally settled there; in other words, option buyers as a whole would receive the smallest payout. This endpoint uses this method to give a max_pain_price for each expiration date.
How Useful Is the Max Pain Price as a Reference?
It is often used to watch where the price may move toward before expiration, but it is only a statistical result calculated from the open interest structure and cannot be treated as a price forecast. For expiration dates with very small open interest, the max pain is also of limited reference value.
How Do I View Options Max Pain for ETH, SOL or XRP?
Just change symbol to ETH, SOL or XRP. Currently only these four coins are supported, and the supported exchanges are Deribit, OKX, Binance and Bybit.
