Return a compact options chain snapshot for one exact Yahoo Finance underlying symbol and one exact expiration returned by options_expirations, with bounded contract rows and high-signal open-interest and volume summaries.
Output

Example use cases
Trader scouting high-OI options strikes
“Show me the options chain for SPY expiring on 2025-03-21 and highlight which strikes have the highest open interest and volume — I want to see where the big money is positioned.”
Earnings options activity check
“Grab me a compact options chain snapshot for NVDA for the expiration closest to their next earnings — I want to see the calls and puts with open interest and volume for the top contracts.”
Portfolio hedging expiry review
“What does the options chain look like for MSFT expiring on 2025-06-20? Give me the strike prices, open interest, and volume for calls and puts so I can see if there's good liquidity for a hedge.”
Technical details
Endpoint
POSThttps://mesh.heurist.xyz/x402/agents/YahooFinanceAgent/options_chainWhen to prefer
Use this endpoint when you need a quick, bounded options chain snapshot for a specific ticker and expiration — especially useful when you already have valid expiration dates from the companion options_expirations endpoint. Prefer this over raw Yahoo Finance scraping when you need structured open-interest and volume summaries in a compact, agent-ready format. Ideal for options flow analysis, earnings plays, and hedging research within an automated agent workflow.
Side effects
- Invalid or unrecognized Yahoo Finance symbol returns an error or empty result
- Expiration date not matching an available expiry (must use one returned by options_expirations) causes a failure
- Symbol has no listed options (e.g. non-optionable stocks) returns empty or error
- Exceeding rate limits or payment failure returns a 402 or rate-limit error
- Network timeout from Yahoo Finance data source causes partial or failed response
