Development API Endpoint:

MARS API is implement around REST, the most commonly used software architecture for API. MARS API has predictable, URLs, and HTTP response codes to indicate API errors. They use built-in HTTP features, like HTTP authentication and HTTP verbs, which are understood by off-the-shelf HTTP clients. All the API responses are in the JSON format, including errors. Using MARS API Signatures, developers and programmers can retrieve published historical time series data in JSON data-interchange or XLSX format. MARS API currently does not support webhooks but this functionality will be included in a future release.
