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
Returns a JSON object with two arrays — 'calls' and 'puts' — each containing contract-level data: contract symbol, strike, bid, ask, last price, volume, open interest, implied volatility, percent change, in-the-money flag, and last trade date. Also includes the ticker, as-of date, the expiration date queried, a list of all available expirations, and the aggregate put/call volume ratio.
Example use cases
Earnings play options research
“I'm considering an earnings trade on NVDA — can you get me the full options chain so I can see which strikes have the most open interest and what implied volatility looks like across calls and puts?”
Covered call strike selection
“I own 100 shares of MSFT and want to sell a covered call — show me the available call strikes and premiums for the next two expirations so I can pick the best one.”
Put/call sentiment check
“What's the put/call volume ratio on SPY right now? Pull the options chain and tell me if the market is leaning bearish or bullish based on today's trading.”
Technical details
Endpoint
GEThttps://x402-stock-indicators.vercel.app/options/%7Bticker%7D?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need structured, contract-level options chain data — including implied volatility, open interest, and put/call ratios — without setting up an API key or subscription. Ideal for agents that pay per-call in USDC via x402, need derivatives data alongside other financial data from the same provider, or require a lightweight pay-as-you-go model for occasional options lookups rather than a brokerage API integration.
Side effects
- Invalid or unrecognized ticker symbol returns an error or empty chain
- Payment not received or x402 handshake fails — returns HTTP 402 requiring USDC payment
- No options data available for the requested expiration (e.g. non-standard expiry) returns empty arrays
- Market closed or data provider outage may return stale or unavailable data
- Rate limiting or upstream Yahoo Finance throttling may cause transient failures
