How this service works
The options chain for a US-listed underlying: every listed contract with its strike price, expiration date, call or put type, exercise style, contract ticker, and shares per contract. Filter with ?expiration_date=YYYY-MM-DD, ?contract_type=call|put, ?strike_price=, ?expired=true|false, and ?limit=. Use to discover which option contracts exist before pulling price history. From x402stock
Output
Returns a list of options contracts for the given ticker, each containing the contract ticker symbol, strike price, expiration date, call or put type, exercise style (American/European), and shares per contract. Supports pagination via limit and ordering. Designed to be used before fetching price history for specific contracts.
Example use cases
Pre-analysis options discovery for a stock
“Before I start analyzing option prices, show me every listed contract for TSLA — both calls and puts — so I know which tickers to pull history for.”
Expiration-specific contract lookup
“List all the call options for SPY expiring on 2025-06-20 so I can see which strike prices are available.”
Targeted put contract screening
“Show me all unexpired put contracts for AAPL with a strike price of 200 — I want to see the contract tickers and exercise style.”
Technical details
Endpoint
GEThttps://agents.x402stock.xyz/api/v1/options/:ticker?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need to discover which options contracts exist for a US-listed stock or ETF before fetching price data, greeks, or historical series. It is the correct first step in any options workflow — acting as a contract catalog. Prefer this over price endpoints when you don't yet know the specific contract ticker symbols you want to analyze.
