  • set_profile

    Step 1 of the lint. Declare what the app does (activities) and where it will operate (jurisdiction slugs), from the app's own code: ask the user which app if they have not said, and lint only one whose code you can open (the open folder, a public repository, one the user connect…

  • run_lint

    Step 2 of the lint, and the one that returns findings. Pass the activities and jurisdictions set_profile validated, and get lint-style findings: which obligations apply, with severity (warn/info), citation, as_of_date, staleness, and confidence. warn: a live obligation binds the…

  • get_law

    One jurisdiction's law from the LexLint law library, across all thirteen topics LexLint covers: AI law, scraping/crawling and access legality, personal-data and biometric privacy, product-security and cyber-resilience law, communications law (marketing messages, calls and texts,…

  • resolve_domain_jurisdiction

    Best-effort mapping from a domain to the jurisdiction whose law governs its OPERATOR, for feeding into the other tools. Never uses server or edge-node location; IP addresses are refused. Costs one to four upstream requests, varying with how many domain-label candidates it tries…

  • check_access

    Preflight. Reports whether an UnGovr Open Data key reached LexLint, whether it is valid, how much of today's free allowance is left and when it resets, how current the law library is, and whether the LexLint plugin you are running is the latest published one. Call this first: a…

  • submit_feedback

    Send the developer's feedback on LexLint to the people who build it, recorded against their UnGovr account so we can write back. Run this ONLY on the developer's explicit yes. It may be raised unprompted in exactly one place, the close of a lint run whose upload approval was dec…

  • upload_lint_run

    Store one lint run on the LexLint portal, against the UnGovr account that signed in or owns the key, and return the portal URL and, for a trial key, a share URL that opens the run with no sign-in for 30 days. This is the closing step of every run that produced findings, raised u…

A client that cannot sign in sends your own UnGovr Open Data key here, which LexLint checks against UnGovr's key store and meters per request: an account key on the daily allowance it shares with data.ungovr.org, a trial key on its one-off t…
