Options

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).

📄️ Quotes

Retrieve a real-time or historical quote for a specific option contract, identified by its OCC option symbol.
