| Tool | Description | Behaviour |
|---|---|---|
| calculate_supplier_deadlines | Calculates a construction material supplier's preliminary notice and lien filing deadlines from delivery events (contract supplier-events-v2), for questions that need deadline dates. Reviewed baselines cover Florida and Kansas private projects; other states and public projects return review_required, which is a valid result, not an error. How the parameters depend on each other: last_delivery_date is required when deliveries_complete is true. Florida (FL) takes florida_final_payment_status and florida_termination_status; Kansas (KS) takes kansas_extension_status; these are rejected for other states. Each takes yes, no or unknown: an omitted or unknown answer keeps the affected deadline under review, and a blanket review flag is not accepted. A Florida event date is accepted only with the matching yes answer. Delivery dates are furnishing dates, not invoice dates. Returns JSON with an overall status (calculated or review_required), preliminary_notice and lien_filing (each with its own status: calculated, not_required, review_required or awaiting_final_delivery, plus deadline, days_from_now, description and statute source_url), critical_warnings, statute_citations, an exact echo of the submitted inputs and a disclaimer. Invalid or contradictory facts return an error naming the field before any API call. Public, stateless and read-only: no key needed, nothing is stored, and no notice is sent or lien filed. Not legal advice. | Read-only |
| get_state_lien_guide | Returns LienDeadline's editorial mechanics lien and preliminary notice guide for one state or DC: rules (rule summary with statute citations), deadline_rows (deadline table), faqs (common questions) and source_url (the guide's web page), roughly 4 KB of JSON. For questions about how a state's lien or notice rules work, why a deadline falls where it does, or which statute applies. An unknown state code returns an error. The guide is an editorial reference, not a calculation: its day counts are summaries, not computed deadlines. Public and read-only; no key needed. | Read-only |
| list_state_lien_guides | Lists every published state lien guide in one response, without pagination: count plus state_code, title and slug for all 50 states and DC, in alphabetical order by state name. It lists editorial guides only and does not indicate which states have calculated deadlines. Takes no parameters. Public and read-only; no key needed. | Read-only |
