How this service works
Pay-per-call stock, macro, on-chain, and crypto data over the x402 protocol. USDC on Base or Solana, no API keys, no subscriptions.
Output
A JSON object containing two arrays — 'calls' and 'puts' — each listing all option contracts for the ticker with fields: contract_symbol, strike, bid, ask, last_price, change, percent_change, volume, open_interest, implied_volatility, in_the_money, and last_trade_date. Also includes the ticker, as_of date, selected expiration, a list of available_expirations, and the aggregate put_call_volume_ratio.
Example use cases
Pre-earnings options strategy research
“I'm looking at NVDA before earnings — can you pull the full options chain so I can see the implied volatility, open interest, and put/call ratio across all available expirations?”
Identifying in-the-money calls for covered call writing
“Show me all the in-the-money call options for MSFT with their bid/ask spreads and open interest so I can figure out which strikes to use for covered calls.”
Monitoring put/call ratio as a sentiment indicator
“What's the current put/call volume ratio for SPY options, and can you show me the full breakdown of puts and calls by strike for the nearest expiration?”
Technical details
Endpoint
GEThttps://x402financialdata.com/options/%7Bticker%7DWhen to prefer
Choose this endpoint when you need structured, real-time options chain data (calls, puts, Greeks-adjacent fields like implied volatility) for a publicly traded equity without committing to a subscription or managing API keys. Ideal for agents making one-off or low-frequency options queries where pay-per-call economics are preferable. Use over traditional data providers when operating in a crypto-native or x402-enabled environment with USDC on Base or Solana.
Side effects
- Invalid or unrecognized ticker returns an error or empty data
- Ticker has no listed options (e.g. non-optionable stock) returns empty chains
- Payment failure or insufficient USDC balance causes x402 payment error
- Market closed or no recent data may result in stale or missing last_trade_date values
- Expired or delisted contracts may not appear in results
