How this service works
Public data and utility APIs paid per call in USDC on Base (x402). No accounts, no API keys. 174 routes: crypto/equity data, onchain reads, DNS/email/security intel, geo/weather, x402 payment diagnostics, dev utilities and more.
Output
Returns a JSON object with a count of options contracts, the base currency (e.g. BTC), and an array of option records each containing: instrument name, type (put/call), strike price, mark implied volatility (mark_iv), and open interest.
Example use cases
Scanning BTC options for trading setups
“Show me the full Bitcoin options chain right now — I want to see the strike prices, whether they're puts or calls, the mark implied volatility, and open interest for each contract.”
Monitoring crypto options market sentiment
“What does the current BTC options market look like? I need the open interest and implied vol across all strikes to gauge where the market is positioned.”
Researching crypto derivatives for a report
“Can you pull the BTC options chain data including instrument names, strike prices, put/call type, and mark IV? I'm compiling a derivatives market overview.”
