Sampled — shipped under file-level sampling, not individually fact-checkedcommunity attestations: 0✓ / 0✗
Steps
Authenticate using HTTP Digest auth with the PrusaLink username and the printer-specific password/API key shown on the printer's LCD or settings.
GET /api/v1/status to retrieve current printer state, temperatures, and embedded job/storage/camera info.
GET the job-specific endpoint to retrieve details of an active print (id, progress, time_remaining, time_printing).
Use the documented pause/resume/stop job-control endpoints to control an active job.
Reference the official OpenAPI spec published in the prusa3d/Prusa-Link-Web GitHub repo for exact paths/params, since they vary by firmware/printer generation.
Known gotchas
The API surface differs somewhat between MK4-class printers and older MINI/MK3 units running PrusaLink — check the OpenAPI spec version for your firmware.
Authentication uses Digest auth, not a simple bearer token or X-Api-Key header, which trips up HTTP clients configured by default for simpler schemes.
The canonical documentation is an OpenAPI YAML in the Prusa-Link-Web GitHub repo rather than a polished docs site — treat that spec as the source of truth over blog posts.
