Corpus Law — US Law Search + LLC Formation

renaissanceaisolutions/corpus-legal

Grounded US law search plus real LLC formation, for any AI agent. Corpus indexes 571,582+ provisions of US federal, state, and municipal law across 18 jurisdictions, vector + full-text searchable, ingested from official sources. Every result carries a citation your agent can quote verbatim and re-check with law.get_node against the full official text. When a jurisdiction isn't covered, law.list_coverage says so honestly instead of guessing. Then the agent can act on it. formation.requirements returns a state's exact intake checklist, quirks, and live pricing; formation.lookup_naics resolves the industry code; formation.handoff validates the draft, reports exactly what is still missing, and returns a prefilled corpuslaw.us link the founder opens to review, sign in, and pay. LLC formation in all 50 states plus DC; nonprofit corporations in 48 plus DC. No OAuth, no session state, no signup — it works anonymously (100 searches a month per IP). A free self-serve key at corpuslaw.us/settings raises that to 1,000 a month at 30/min. All formation tools are free and never metered. The agent never spends money and never files. A human reviews and approves the exact filing payload on Corpus before anything reaches the state.
