I'm building a rest API that serves exclusively JSON. It might one day be consumed by a browser based app. Is there anything I should do on my end to prevent XSS attacks?

Its up to the data consumer to sanitize data so perhaps you supply a document of potential risks that come from using your API.

For example where does your API get its data? Are you sanitizing the data? Is that a risk the consumer might need to know and how would they mitigate the risk.
