Update timeline

investigating Dec 20, 2016, 09:52 AM UTC

We are investigating an issue affecting some clients using our Time Series (/time-series.json) API endpoint. The issue affects requests to `/time-series.json` which specify the same `start` and `end` dates (i.e. requests for a single day of data) and do not specify a subset of currencies via the `symbols` parameter. These requests incorrectly return a `400` error. All other API endpoints, and all other normal requests to the Time Series API (i.e. in all cases where a client requests multiple days of data or requests a specific subset of currencies via the `symbols` parameter), are unaffected. We will update this page as soon as we have resolved or have further information. Please contact us at [email protected] with any questions or concerns.
