A function with typed inputs. Its response is checked against the schema.

Path parameters

optionSymbolstring required

The option symbol (as defined by the OCC) for the option you wish to lookup. Use the current OCC option symbol format, even for historic options that quoted before the format change in 2010.

Query parameters

format'csv' | 'json'

The format parameter is used to specify the format for your data. We support JSON and CSV formats. The default format is JSON.

datestring date

Use to lookup a historical end of day quote from a specific trading day. If no date is specified the quote will be the most current price available during market hours. When the market is closed the quote will be from the last trading day. Accepted date inputs: ISO 8601, unix, spreadsheet.

fromstring date

Use to lookup a series of end of day quotes. From is the oldest (leftmost) date to return (inclusive). If from/to is not specified the quote will be the most current price available during market hours. When the market is closed the quote will be from the last trading day. Accepted date inputs: ISO 8601, unix, spreadsheet.

tostring date

Use to lookup a series of end of day quotes. To is the newest (rightmost) date to return (exclusive). If from/to is not specified the quote will be the most current price available during market hours. When the market is closed the quote will be from the last trading day. Accepted date inputs: ISO 8601, unix, spreadsheet.

countbackinteger

Countback will fetch a number of quotes before (to the left of) to. If you use from, countback is not required.

dateformat'spreadsheet' | 'timestamp' | 'unix'

The dateformat parameter allows you specify the format you wish to receive date and time information in.

limitinteger

The limit parameter allows you to limit the number of results for a particular API call or override an endpoint's default limits to get more data.

offsetinteger

The offset parameter is used together with limit to allow you to implement pagination in your application. Offset will allow you to return values starting at a certain value.

headersboolean

The headers parameter is used to turn off headers when using CSV output.

columnsstring

The columns parameter is used to limit the results and only request the columns you need. The most common use of this feature is to embed a single numeric result from one of the end points in a spreadsheet cell.

humanboolean

Use human-readable attribute names in the JSON or CSV output instead of the standard camelCase attribute names.

Response

Every field is present on a request without columns. columns returns only the listed fields, in the listed order, and human=true renames them. With format=csv the same fields come as CSV, where a null value is an empty cell; CSV is served with 200 even when the data comes from the cache.
