    Why it is in this group

    • The name "compare_states" says "compare": a word for reading.
    Description, as the server wrote it
    The same compliance topic across several US states, for deciding where to incorporate or for an organization that operates in more than one state. Each state's records carry their own citation and verification status; a record marked review_required is unsettled and must not be presented as a settled rule. Accepts up to eight states.
  • get_filing_deadlinesEvery requirement in one US state that has a filing deadline attached, with the deadline in plain words, the form or portal, the fee, and the official citation.No findings

    Why it is in this group

    • The name "get_filing_deadlines" says "get": a word for reading.
    Description, as the server wrote it
    Every requirement in one US state that has a filing deadline attached, with the deadline in plain words, the form or portal, the fee, and the official citation. Use this for 'what is due and when'. Deadlines on records marked review_required are not settled and must be shown as unconfirmed.
  • get_state_requirementsNonprofit compliance requirements for one US state, from 501c3.help's sourced records: formation, governance, charitable solicitation registration, reporting, tax and employment.No findings

    Why it is in this group

    • The name "get_state_requirements" says "get": a word for reading.
    Description, as the server wrote it
    Nonprofit compliance requirements for one US state, from 501c3.help's sourced records: formation, governance, charitable solicitation registration, reporting, tax and employment. Every record carries its official citation and a verification status. Records marked review_required are unsettled and must be presented as such, never as a settled rule. Optionally narrow by topic. Returns a limited number of records, not the whole state.

This is not a safety rating, and no finding is not a safety guarantee. The groups and findings come from fixed checks of the tool definitions the server returned on the date shown, not from its code or what it does when called. How the checks work.
