How this service works
Reads the public option book summaries of Deribit and aggregates them per expiry. iv_atm is the mark implied volatility of the strike closest to the forward, averaged over call and put, and the strike used is named. term_structure lists iv_atm against days to expiry. put_call_ratio is reported twice and never mixed: once by 24h volume and once by open interest. open_interest_by_strike and key_strikes show where positions actually sit, above and below the forward. max_pain comes with the complete
Output
Returns aggregated options book data for the requested underlying and expiry, including: ATM implied volatility (averaged over nearest-to-forward call and put), term structure (IV vs. days to expiry), put/call ratio by 24h volume, put/call ratio by open interest, open interest by strike, key strikes above and below the forward, and max pain with full supporting data.
Example use cases
Pre-expiry options positioning check
“What does the BTC options book look like for the nearest Deribit expiry? Show me ATM IV, where open interest is concentrated, and where max pain lands.”
ETH term structure analysis
“Pull the full ETH options term structure from Deribit across all open expiries so I can see how implied volatility changes with time to expiration.”
Put/call sentiment check before trade
“What's the put/call ratio for ETH options on Deribit right now, both by 24-hour volume and by open interest, for the next expiry?”
Technical details
Endpoint
POSThttps://markt.halowerk.com/options?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a structured, aggregated view of Deribit's crypto options market for BTC or ETH — specifically ATM implied volatility, term structure, put/call sentiment, and strike-level open interest — rather than raw order book data or single-instrument Greeks. It is purpose-built for options market structure analysis and max pain computation on Deribit, not for generic options data from other exchanges.
Side effects
- Invalid or unsupported underlying (not BTC or ETH) returns validation error
- Expiry date not found on Deribit returns empty or error response
- moneyness_range outside [0.1, 1.0] returns schema validation error
- Deribit API unavailable causes upstream timeout or failure
- No open interest data for specified expiry may result in sparse output
