Fastmarkets APIs

A key part of the data solutions provided by Fastmarkets are the various REST APIs designed to provide data in a flexible, performant and secure way. For data license customers, these APIs are ideal for retrieving and processing Fastmarkets data by their own services.

This section gives details of two of these APIs with examples of how they are typically used.

The following public APIs are available for use to authorized customers:

 

Fastmarkets Authentication API

This API is used to authenticate the calling service. It will also generate an access token needed when calling other Fastmarkets APIs for authorization purposes. 

See Fastmarkets Authentication API for more information.

 

Fastmarkets Physical Prices API

Used to return current and historic physical prices as well as associated instrument data.

See Fastmarkets Physical Prices API for more information.

 

API technical information

To find out more about the more technical details of working with our APIs - see API technical information
