How this service works
The options chain for a currency and expiry sorted by strike: bid, ask, mark, mark implied volatility, open interest, 24h volume and the underlying, plus the list of available expiries. Use it when an agent is pricing a strategy, finding liquid strikes or reading the volatility smile for a specific expiry.
Output
Returns a JSON object with the currency, expiry label, expiry timestamp, spot price of the underlying, list of available expiries, and an array of option contracts each containing instrument name, strike, type (call/put), bid, ask, mark price, mark implied volatility, 24h volume, 24h volume in USD, and open interest. Also includes the data source (Deribit) and the fetch timestamp.
Example use cases
Scan near-expiry BTC options
“Give me all BTC options expiring at the nearest available date — both calls and puts — with their mark price and implied volatility, up to 500 rows.”
Filter ETH puts for a specific expiry
“Fetch only put options for ETH expiring on 26SEP26 from Deribit, up to 100 rows, so I can see which strikes have the most open interest.”
Monitor BTC implied volatility surface
“Pull the BTC call options chain for the 26DEC26 expiry and show me the implied volatility and 24-hour volume in USD for each strike — I want to map the vol surface.”
Technical details
Endpoint
POSThttps://agent402.tools/api/crypto-options-chainWhen to prefer
Use this endpoint when you need structured, ready-to-use crypto options chain data from Deribit without managing your own Deribit API credentials or WebSocket connections. Ideal for agents that need to analyze options pricing, implied volatility, or open interest for BTC or ETH in a pay-per-call, no-signup model. Prefer over direct Deribit integration when you want simple REST access and per-call billing via USDC/x402.
Side effects
- Invalid expiry label returns empty or error response
- Unsupported currency (not BTC or ETH) causes validation failure
- Limit exceeding 500 is clamped or rejected
- Deribit API downtime causes upstream data unavailability
- Stale data if fetched during low-liquidity periods
