SL1S running firmware@`1.7.1` returns API version `0.1`

[john-rodewald]

Querying /api/version on my Prusa SL1S yields the following result (truncated):

{
    "api": "0.1",
    "hostname": "prusa-sl1s",
    "server": "1.1.0",
    "text": "Prusa SLA 1.0.5"
}

This is a problem because there are tools that integrate with Prusa printers which ensure the API version is valid.

Is this expected behaviour? It also seems strange that the firmware version (1.7.1) is nowhere to be found in the response.

The SL1S is several weeks old and has only seen one firmware update, namely from 1.7.0 to 1.7.1.

Interesting. Where can I find more information on the topic? I have these questions in particular:

• Why is the API at such a low version? Is the SL1S not a mature product at this point?
• How does the SL1S v0.1 API differ from the v2 API that runs on other Prusa printers? Are they cross-compatible?
• What's missing to make the jump to v1?
