GET /v1/compute/add-ons

Authentication

Send an API key as a bearer token. The key must carry the sites.view permission; a key without it is refused with 403, not 404.

This endpoint takes no organisation id. Your key already identifies the organisation it belongs to, and the response is scoped to it.

Try it

Replace anything in angle brackets with your own values, and the key placeholder with a key from your dashboard.

curl -X GET https://api.zinndigital.com/v1/compute/add-ons \
  -H "Authorization: Bearer zdk_live_…"

Signed in? The API console in your dashboard fills in your real organisation id and your own key, and runs the request against the live API so you can see the actual response. Open this endpoint in the API console

Details

The add-on catalogue — bare, CloudLinux, Plesk, and the managed service — priced in the currency asked for and filtered to what is actually in stock. ⭐ These are the decisions `docs/127` §2 took on 2026-08-15 (D1–D5), expressed as rows a customer can buy. They are **orthogonal to the machine size**: a customer picks a size *and* an add-on, and the two multiply rather than choosing between each other. What the API calls a `ComputeTier` elsewhere is the SIZE; this is the software. ⛔ **An empty list is the correct answer on the resold range**, not an error. There the supplier installs its own managed image and exposes no `user_data` seam, so there is no add-on question to answer — and rendering a picker with one disabled option would imply the others are coming. ⛔ **A row absent from this list in one currency is not sold in that currency**, never converted at today's rate: a machine and the add-on beside it must not be quoted from two different sources, or the same basket costs two different amounts on two days. Requires `sites.view`.
