All calls to the REST endpoints need to be made with the following header set: `Authorization: Bearer {auth_token}` Note the space between Bearer and the token itself. An example of the data to be set (with a truncated token) is: `Bearer eyJhbGciOiJIUzUxMiIIkpXVCJ9.eyJqdGkiOiIyNmQ2` Attempting to access a resource without the header included will result in a permission denied error. The response body will contain the details in the following format: `{ “error”: “”, “status”: }` When accessing the streaming web sockets it is not possible to include a header on the initial GET request, so instead the token needs to be sent over the web socket before the stream will start. See 'Connecting to a Streams Endpoint' for examples of how to do this. ## Security All calls to the API must be made over HTTPS. This ensures that the tokens used for authentication/authorisation cannot be intercepted and used to access content without permission. For the same reason, you must make sure that you do not expose your token externally, though this is mitigated by the use of the IP whitelist. We do not provide a fixed set of IP addresses for our services. Therefore if you use IP-based security rules, you will need to dynamically resolve our services IPs with each request that you make. Additionally, for DNS resolution we present a 1 hour TTL and you will also need to ensure this is being effectively respected when resolving from CNAME to host. ## Date & Time Formats All DateTime objects are returned using the ISO 8601 combined format. For more information about ISO 8601, please read [here](http://en.wikipedia.org/wiki/ISO_8601). Examples:\ • Date only – 2024-06-01\ • UTC Time only – 10:12:54 (also used for match time)\ • Offset time – 17:20-04:00 or 15:15:30+01:00\ • UTC Datetime – 2024-06-01T15:15:30\ Note that the date and time returned in UTC local time. ## Polling limits IMG Arena monitor the incoming traffic from our customers and strive to ensure that traffic is controlled, in-keeping with our guidelines and not unnecessarily excessive. We would suggest a polling rate of 10 requests per second measured over a 5 minute interval. Note that this rate limit is across all of our legacy sports and endpoints. If you break this late limit, your requests will start to get throttled, for more information, please contact --- # Agent Instructions This documentation is published with GitBook.

Perform an HTTP GET request on the current page URL with the `ask` query parameter: ``` GET https://docs.sportradar.com/tennis/documentation-1/api_information.md?ask= ``` The question should be specific, self-contained, and written in natural language. The response will contain a direct answer to the question and relevant excerpts and sources from the documentation. Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
