Options (C# SDK)
The C#/.NET SDK from Market Data provides methods to streamline your use of the Options endpoints. These methods provide a typed interface over the underlying HTTP requests and responses; every method is asynchronous and accepts an optional CancellationToken.
Reach the resource through client.Options. For CSV output, call the paired *CsvAsync method of the same name (for example GetChainCsvAsync).
Options Endpoints
📄️ Chain

Call GetExpirationsAsync on the C# SDK Options resource to list expiration dates for an underlying symbol, filtered by strike or historical date.
📄️ Quotes
Retrieve a real-time or historical quote for a specific option contract, identified by its OCC option symbol.
📄️ Lookup
Turn a human-readable option description into a well-formed OCC option symbol with the C# SDK and its OptionsLookupRequest type.
