+## `GET https://api.faelix.net/connectivity/xdsl/test/zen/ZW01234567XX/available`
+
+Returns a dict mapping test types to information about the tests.  Will only return tests available for that type of line.
+
+```json

+## `POST https://api.faelix.net/connectivity/xdsl/test/zen/ZW01234567XX/test/xxxx-service-test`
+
+Starts a test, and returns a redirect (via `Location: ` header) where you can then `GET` the results.
+
+```json

+
+Returns a blob of raw JSON test results.  Will be different for different test types.  Not a valid result (yet) if the `dataFrom` key has no value associated.
+
+We set two additional keys to make interpreting simpler: `failure` (true or false) and `suspicious` (true or false).
