Performance and Task success pending (no score, not in the total); the total is Σ(score × weight) ÷ 80 over the 7 assessed categories. \"This run\" is each category's share of the 100 points.\n\n| Category | Weight | This run | Score (0–100) | Points |\n| --- | --- | --- | --- | --- |\n| Reliability | 16% | 20 | 55 | 11.0 |\n| Performance | 10% | pending | pending | n/a |\n| Schema \u0026 documentation | 13% | 16.2 | 60 | 9.8 |\n| Agent ergonomics | 13% | 16.2 | 48 | 7.8 |\n| Security \u0026 auth | 14% | 17.5 | 36 | 6.3 |\n| Payments \u0026 pricing | 10% | 12.5 | 60 | 7.5 |\n| Task success | 10% | pending | pending | n/a |\n| Maintenance \u0026 community | 7% | 8.8 | 17 | 1.5 |\n| Transparency \u0026 trust (editorial 44, provenance 83) | 7% | 8.8 | 64 | 5.6 |\n| Negative events | up to −15 | up to −15 | none recorded | 0 |\n| **Total** | | | | **49.4 → D** |\n\n### Why each score\n\n- Reliability 55 (checked 2026-11-03): Read with the local-software lines, as software the owner runs on the printer or a Raspberry Pi. The Pi edition installs from the PrusaLink package on PyPI or a Raspberry Pi OS image, with supported Pi models and printer firmware 3.14.0 stated in the release notes, and the firmware editions ship with the printer; the PyPI page answered a script challenge and was not read (17 of 20). A python-tests.yml workflow and four test modules are in the repository, and a CI fix was committed on 9 October 2026, but no run result was read (15 of 25). 102 open issues on 3 November 2026; the newest 25 run from August 2024 to May 2026, include print failures, parse errors and a Pi that stops after reboot, and show no maintainer reply (8 of 25). The ChangeLog marks the 0.7.1rc1 rename of ro to read_only as a breaking API change and records API version bumps, but there is no stated versioning rule (10 of 15). The Pi edition is 0.8.1 and the spec is 1.0.0-draft, though both have shipped to customers for years (5 of 15). 17 + 15 + 8 + 10 + 5 = 55.\n- Performance: Pending. Latency is measured per call by our probes, which haven't run yet, so this run doesn't score it. Its weight is shared across the assessed categories until the first probe window closes.\n- Schema \u0026 documentation 60 (checked 2026-11-03): OpenAPI 3.0.1 in the Prusa-Link-Web repository covering 19 paths and 33 operations, marked 1.0.0-draft, last changed 18 July 2024, with malformed 204 lines and keys containing spaces (20 of 25). No llms.txt or Markdown docs for agents (0). One-line summaries per operation and no guidance on when to use or avoid one (8 of 20). Enums for printer, job, storage, transfer and file types, required fields on response schemas, and ?0 or ?1 header switches; request bodies are binary or empty (11 of 15). Error responses listed per operation with an Error schema of title and text, and few request examples (9 of 15). /api/v1 paths, GET /api/version, and a dated ChangeLog in the Pi repository (12 of 15). 20 + 0 + 8 + 11 + 9 + 12 = 60.\n- Agent ergonomics 48 (checked 2026-11-03): Read as an API. Responses are small telemetry and file objects, but a status call returns everything with no field selection (15 of 25). File listings are flat with no paging, filter or size control (5 of 20). Documented 401, 404, 409, 408 and 503 responses with a title and text an agent can read, though 409 does not say which state blocked the call (12 of 20). Pause, resume and upload are PUT, Overwrite guards uploads and Force guards folder deletes, but there is no idempotency key and a repeated POST to start a print depends on the printer's state (10 of 20). Few parameters and sensible defaults, no official SDK in any language (6 of 15). 15 + 5 + 12 + 10 + 6 = 48.\n- Security \u0026 auth 36 (checked 2026-11-03): One credential per printer, a digest username and password shown on a Buddy printer's screen or one API key on the Pi edition, resettable but without scopes or expiry; digest keeps the secret out of the request (12 of 30). No read-only mode and no confirmation before a stop, a delete or a firmware update (2 of 20). The API returns the owner's own file names and telemetry, so little untrusted content (10). No audit log or per-call visibility documented (2 of 15). Prusa's security.txt is valid to 1 June 2027 with a policy page that rewards reports and answers within 5 working days; no bug bounty amounts, SOC 2 or ISO 27001, and the policy covers websites rather than printers by name (10 of 20). 12 + 2 + 10 + 2 + 10 = 36.\n- Payments \u0026 pricing 60 (checked 2026-11-03): Read with the self-hosted rule. No payment protocol (0). The software is free with nothing to buy, so 20, 20 and 20 on the last three lines. It needs an Original Prusa printer, and the Pi edition a Raspberry Pi, which are hardware the owner already has.\n- Task success: Pending. Task success needs the category task suites run through each tool, which haven't run yet, so this run doesn't score it. Its weight is shared across the assessed categories until then. A data provider's data-quality score is published on its listing now and becomes half of this category when it's scored.\n- Maintenance \u0026 community 17 (checked 2026-11-03): The Pi edition's last release is 0.8.1 of 2 July 2024, more than 180 days ago; commits on 14 and 17 October and 2 and 3 November 2026 bump the version to 0.9.0.dev0 and fix the multi-instance image without a release (5 of 30). No release in the last 90 days (0). Of the newest 25 open issues, those from 2025 and 2026 have 0 to 9 comments and none shows a maintainer reply; the forum and help centre answer owners (5 of 25). No official SDK; PrusaSlicer is a client (0 of 15). CI workflow, ruff and dependabot bumps as recent as 2 November 2026 (7 of 10). 5 + 0 + 5 + 0 + 7 = 17.\n- Transparency \u0026 trust 64 (checked 2026-11-03): Source for the Pi edition and the web interface is public, but setup.py declares Freeware with no licence file, the web interface is GPL-3.0 and the spec names AGPLv3, so the licence of the Python edition is unclear (15 of 30). Local software whose data stays on the printer unless registered with Prusa Connect; Prusa's privacy policy of 1 August 2022 gives retention periods per service and names processors and group companies, but says nothing about PrusaLink itself (15 of 30). The ChangeLog flags one breaking change and the website terms promise 30 days' notice for service changes, with no API deprecation policy (6 of 20). Telemetry goes to Prusa Connect only when the owner registers the printer, which the wizard makes optional, and no separate telemetry disclosure was found (8 of 20). 15 + 15 + 6 + 8 = 44.\n\nFix list, everything this grade says the listing lacks, the biggest gain first (18 items). What it covers is at https://www.anchorterminal.com/fixes/prusalink.md (JSON https://www.anchorterminal.com/fixes/prusalink.json). The whole list for a coding agent comes from `POST https://www.anchorterminal.com/api/v1/fix-list` with `{\"listing\": \"prusalink\", \"plan\": \"read\"}`, free while the beta runs\n\n### What we couldn't check\n\n- unchecked: the PyPI release list for PrusaLink (pypi.org answered the project page with a script challenge, and its JSON endpoint is disallowed by robots.txt). Release dates come from GitHub releases and the ChangeLog\n- unchecked: the result of the python-tests.yml workflow on the default branch, and the Buddy firmware's own PrusaLink implementation (prusa3d/Prusa-Firmware-Buddy was not read), including whether an API key still works beside digest on current firmware\n- unchecked: the Prusa Connect terms and conditions, which the website terms name as governing PrusaLink and Prusa Connect; their URL was not found on the pages read\n- firstReleased is 23 November 2020, the ChangeLog's oldest dated entry (0.1.2). The repository was created on 1 June 2020\n- Judgement call on the licence. setup.py declares Freeware and the repository has no licence file, while Prusa-Link-Web is GPL-3.0 and the spec names AGPLv3, so transparency scores the Python edition as unclear rather than open source\n- Judgement call on the surface. One listing covers the firmware editions and the Pi edition, since both answer the same /api/v1 spec; the Pi edition's ChangeLog says its API version tracks the one xBuddy reports\n- Prusa's website terms forbid automated extraction of website content including scraping, recorded as a fact; the help centre asks for 10 seconds between requests, which was kept\n\n### Sources\n\n- OpenAPI spec: \u003chttps://raw.githubusercontent.com/prusa3d/Prusa-Link-Web/master/spec/openapi.yaml\u003e (seen 2026-11-03)\n- Prusa-Link repository, shallow clone (ChangeLog, setup.py, CI, tests): \u003chttps://github.com/prusa3d/Prusa-Link\u003e (seen 2026-11-03)\n- Prusa-Link-Web repository, shallow clone (LICENSE, spec history): \u003chttps://github.com/prusa3d/Prusa-Link-Web\u003e (seen 2026-11-03)\n- Prusa-Link README: \u003chttps://github.com/prusa3d/Prusa-Link/blob/master/README.md\u003e (seen 2026-11-03)\n- Prusa-Link releases: \u003chttps://api.github.com/repos/prusa3d/Prusa-Link/releases\u003e (seen 2026-11-03)\n- Prusa-Link commits: \u003chttps://api.github.com/repos/prusa3d/Prusa-Link/commits\u003e (seen 2026-11-03)\n- Prusa-Link repository metadata: \u003chttps://api.github.com/repos/prusa3d/Prusa-Link\u003e (seen 2026-11-03)\n- Prusa-Link open issues: \u003chttps://github.com/prusa3d/Prusa-Link/issues\u003e (seen 2026-11-03)\n- Prusa Connect and PrusaLink explained: \u003chttps://help.prusa3d.com/article/prusa-connect-and-prusalink-explained_302608\u003e (seen 2026-11-03)\n- Wi-Fi and Prusa Connect/Link setup guide (PDF of 13 May 2026): \u003chttps://help.prusa3d.com/wp-content/uploads/generated/prusa-connect-prusalink_1636_guide_413293_en_2026-05-13.pdf\u003e (seen 2026-11-03)\n- about us: \u003chttps://www.prusa3d.com/page/about-us_77/\u003e (seen 2026-11-03)\n- website terms: \u003chttps://www.prusa3d.com/page/general-terms-and-conditions-of-use-of-the-prusa-websites_231226\u003e (seen 2026-11-03)\n- privacy policy: \u003chttps://www.prusa3d.com/page/privacy-policy_231258/\u003e (seen 2026-11-03)\n- security.txt: \u003chttps://www.prusa3d.com/.well-known/security.txt\u003e (seen 2026-11-03)\n- security policy: \u003chttps://www.prusa3d.com/page/security-policy_230500/\u003e (seen 2026-11-03)\n- robots.txt: \u003chttps://help.prusa3d.com/robots.txt\u003e (seen 2026-11-03)\n- RDAP for prusa3d.com: \u003chttps://rdap.verisign.com/com/v1/domain/prusa3d.com\u003e (seen 2026-11-03)\n\n## Score history\n\nEvery move of a score since the listing was graded, newest first, with its cause.

The page links the company's Facebook, Instagram, Twitter and YouTube accounts; no LinkedIn, X or GitHub account for Josef himself is linked from the pages read, so none is listed. PrusaLink's maintainers are seen only as GitHub logins in the repository. Investors were looked for on the about page, which says the company began with no investors and no Kickstarter campaign, and in the website terms and privacy policy, which name Prusa Development a.s. and other group companies; no funding round or outside investor was found and no outside search was made for a founder-run company that says it took none.\n- Prusa Research a.s.: X https://x.com/prusa3d GitHub https://github.com/prusa3d\n\n### Getting support\n\n- Support email: link@prusa3d.cz\n- Help: https://help.prusa3d.com/\n- Help: https://help.prusa3d.com/article/prusa-connect-and-prusalink-explained_302608\n- Community (Prusa forum): https://forum.prusa3d.com/\n- Community (Prusa-Link issues): https://github.com/prusa3d/Prusa-Link/issues\n- Sources: https://www.prusa3d.com/page/about-us_77/, https://www.prusa3d.com/page/general-terms-and-conditions-of-use-of-the-prusa-websites_231226, https://www.prusa3d.com/page/privacy-policy_231258/, https://www.prusa3d.com/, https://www.prusa3d.com/.well-known/security.txt, https://raw.githubusercontent.com/prusa3d/Prusa-Link-Web/master/spec/openapi.yaml, https://github.com/prusa3d/Prusa-Link\n\n## Live (updated 2026-11-04 15:53 UTC)\n\n- security.txt: valid, expires 2027-06-01T00:00:00.000Z\n- Always current: https://www.anchorterminal.com/api/v1/live/prusalink.json\n\n## Probe metrics\n\nNot measured yet. Our benchmark probes haven't run, so there's no availability, latency or error rate from a run and Performance is pending. Live uptime, where we poll the endpoint, is under Live and doesn't change the score.\n\n## Strengths\n\n- OpenAPI 3.0.1 spec with enums for printer and job states and documented 401, 404 and 409 responses on most operations\n- Free, local and offline; the printer needs no cloud account, and the API answers on the printer's own address\n- Shipped in the firmware of every current Original Prusa printer, with a Raspberry Pi edition for the MK3 and MK2.5\n- Prusa publishes a valid security.txt and a disclosure policy that rewards reports\n- Source of the Pi edition and the web interface on GitHub, with CI and dependabot updates\n\n## Weaknesses\n\n- One credential per printer, a digest password or an API key, with no scopes, read-only mode or confirmation before a stop or delete\n- The Pi edition's last release is 0.8.1 of 2 July 2024, and the spec is marked 1.0.0-draft with malformed YAML lines\n- 102 open issues with no visible maintainer reply in the newest 25, and no official SDK\n- No pagination, filtering or output-size control on file listings, and no idempotency keys\n- The Python package's licence is declared as Freeware with no licence file, while the web interface is GPL-3.0\n\n\n\n## Before you call it (notes for agents)\n\n1. Reach the printer by its local address only; use HTTP digest with the username and password from Settings \u003e Network \u003e PrusaLink on a Buddy printer, or X-Api-Key on the Pi edition\n2. Check GET /api/v1/status before any change and expect 409 when the printer is busy; a stop or delete has no confirmation step\n3. Upload with PUT /api/v1/files/{storage}/{path}, set Print-After-Upload to ?1 to start at once, and send Overwrite ?1 only when replacing a file on purpose\n4. Read GET /api/version first, since the Pi edition and the firmware editions report different API versions and the Pi edition lacks Buddy-only fields\n5. Expect no rate limits or retry guidance; poll status at a modest interval rather than on every turn\n\n## Connect\n\nInstall:\n\n```bash\npip install PrusaLink\n```\n\nFirst request:\n\n```bash\ncurl --digest -u \"$PRUSALINK_USER:$PRUSALINK_PASSWORD\" http://\u003cprinter-ip\u003e/api/v1/status\n```\n\nThrough letme: https://letme.dev/prusalink (letme picks it for cad.print, the top-graded tool for the job). letme answers with the pick and how to call it direct.
