Welcome to the TIS API (Tesserae Intertext Service Application Programming Interface) documentation website. This website provides information on the TIS API by describing its endpoints and by providing some examples of how the endpoints are supposed to behave.

If you’re new to the TIS API, we recommend you look at the tutorial to get your bearings.

If you want a refresher on the TIS API, there is an example workflow that might be helpful.

If you want to know more about a particular endpoint, find it under the “Endpoints” dropdown menu (found along the top of the page).
