FilingDesk Data tools (8, 2 write)
write = sends, deletes, buys or postscheck_llc_nameFreeCheck a proposed business name against a state's live registry. REAL results for Wyoming and Delaware only; Florida returns a Sunbiz search link; all other states return unsupported. A verdict is an indication, never a reservation — always show the returned note and verifyUrl.
compare_formation_optionsFreeFactual tradeoffs to help someone decide WHERE to form or WHAT entity type to pick. Returns fixed comparative facts and a required disclaimer — deliberately NOT a recommendation. Present the options neutrally, relay the disclaimer, and let the user choose; a FilingDesk specialist confirms the choice before anything is filed.
compare_llc_costsFreeRank states by what an LLC actually costs. Compares the one-time formation fee, the recurring state cost, and the combined first-year total. Use this for 'cheapest state to form an LLC' style questions rather than guessing.
get_annual_report_deadlineFreeWork out when a state's annual report or franchise tax is next due, the amount owed, and the late penalty. States that key the deadline to the formation anniversary or quarter need formationDate; without it the tool says so instead of guessing a date.
get_llc_feesFreeOfficial LLC formation fee, recurring annual-report/franchise-tax cost, processing time, and known gotchas for a single US state, each with its source URL. Covers all 50 states + DC.
list_filing_statesFreeWhat FilingDesk can do per state: which states it files in today with all-in pricing, which states have real name-checking, and confirmation that fee/deadline data covers all 50 states + DC. Call this before telling a user FilingDesk can file somewhere.
preview_orderwrite actionFreeBuild an exact order summary WITHOUT submitting anything. No side effects. Validates the details, prices the order, and returns a confirmation summary. ALWAYS call this and show the user the returned summary before calling submit_order.
submit_orderwrite actionFreeSubmit a real formation order to FilingDesk. THIS HAS A REAL-WORLD EFFECT: it creates an order and notifies a FilingDesk specialist. Only call after preview_order and after the user has explicitly confirmed the summary. Nothing is charged now — a specialist reviews the order, verifies the name, and emails a payment link. Returns the order reference.
