New Business Filings — Fresh LLC & Corporation Registrations by State

Docs & recipes: pricing math, use-case playbooks and copy-paste API/MCP snippets · practical guide

Pull this week's newly registered LLCs and corporations straight from official state open-data portals. One normalized record per filing (illustrative example):

{
  "entity_name": "Colorado Home Advisory LLC",
  "state": "CO",
  "filing_date": "2026-08-04",
  "entity_type": "Domestic LLC",
  "status": "Good Standing",
  "registered_agent_name": "CARLOS E RUIZ",
  "agent_is_commercial": false,
  "address": "9216 Bauer Ct",
  "principal_city": "Lone Tree",
  "principal_state": "CO",
  "record_id": "20261872783",
  "source": "Colorado Secretary of State (data.colorado.gov)",
  "source_url": "https://data.colorado.gov/resource/4ykn-tg5h.json?entityid=20261872783"
}

Every day, thousands of brand-new businesses register with state governments. They all need banking, insurance, bookkeeping, websites, payroll, phones and office space — and on day one they have none of it. If you buy LLC registration leads from a list broker today, this is the same public-record data at primary-source freshness — filtered, de-noised of formation-mill addresses, and delivered on your schedule instead of theirs.

Commercial registered-agent handling (the de-noising): filings made through formation mills (Registered Agents Inc, Northwest, CSC, LegalZoom, ZenBusiness, …) list the agent's office as the address. With excludeRegisteredAgentAddresses (default on) those addresses are blanked and the record is flagged agent_is_commercial: true, so your outreach lists aren't polluted with 5,000 "businesses" at 30 N Gould St.

Covered states (honest list)

State	Feed	Notes
CO	SOS business entities, updated daily	Full agent name + address
NY	DOS daily filings feed	Filtered to formations (Articles of Organization, Certificates of Incorporation, Applications of Authority). NY doesn't publish agent names
CT	Business registry master file	All entity types, domestic + foreign; agent names live in a separate state dataset (not joined)
OR	"New businesses registered last month"	Rolls monthly — use daysBack ≥ 30 for full coverage. Includes agent names
PA	DOS registered businesses	Creation-date filtered; PA uses registered-office providers (no agent names)
DE	Business licenses (clearly-labeled proxy)	Delaware does not open-source entity formations; new licenses are the closest official free signal

Each state is a small self-contained adapter over a shared Socrata client — new states ship incrementally without touching the rest. The roster above is what is implemented and live-tested today; if a state you need is missing, ask.

Input

{
  "states": ["CO", "NY", "CT", "OR", "PA"],
  "daysBack": 7,
  "excludeRegisteredAgentAddresses": true,
  "entityTypes": ["llc"],
  "socrataAppToken": ""
}

Field	Default	Meaning
states	["CO","NY","CT","OR","PA"]	Which state adapters to run (DE opt-in — it's a licenses proxy)
daysBack	7	Filings dated within the last N days (some states publish with a few days' lag; OR is monthly)
excludeRegisteredAgentAddresses	true	Blank formation-mill office addresses; keep + flag the record
entityTypes	[] (all)	Case-insensitive substrings vs normalized entity type: llc, corporation, nonprofit, …
maxRecordsPerState	20000	Safety cap per state per run
socrataAppToken	— (optional)	Free Socrata app token = higher rate limits across all covered states; anonymous is fine for normal volumes

A zero-config {} run works: the last 7 days across the five core states.

Output fields

Field	Type	Meaning
entity_name	string	Registered legal name
state	string	Two-letter state of the filing feed
filing_date	date	Official formation/filing date
entity_type	string	Normalized type as published (e.g. Domestic LLC)
status	string | null	State status (e.g. Good Standing) where published
registered_agent_name	string | null	Agent as published (null in NY/PA — see state table)
agent_is_commercial	boolean	Filing made through a known formation mill / commercial agent
address	string | null	Street address (blanked when it's a commercial agent's office and suppression is on)
principal_city / principal_state	string | null	Principal place of business where published
record_id	string	State's own record identifier
source / source_url	string / url	Named official portal + deep link to the exact source record

Business-context data only: entity, filing, status and registered-agent (business) information. No officer home addresses, no personal data. Fields a state doesn't publish are null, never missing.

  "input": { "states": ["CO", "PA"], "daysBack": 7, "entityTypes": ["llc"] }

"Give me every LLC formed in Colorado last week that didn't use a formation mill" — one call, agent_is_commercial: false filter on your side.

Pricing

Pay-per-result: $4 per 1,000 records ($0.004/record). Worked math: a daily single-state LLC watch returning ~200 filings costs $0.80/day; a weekly 5-state pull of ~5,000 filings costs $20. Typical commercial "new business lead" providers charge $0.02–$0.09 per lead for the same public-record data — this is 5–20× cheaper, from primary sources, on your schedule. Use entityTypes, states, and daysBack to keep row counts (and cost) exactly as tight as your territory.

Honest limits

• Coverage is the six listed states only — this is not a national registry. DE is a business-license proxy, clearly labeled, because Delaware does not open-source formations.
• Agent names are absent where the state doesn't publish them (NY, PA; CT unjoined).
• States publish with a lag of a few days; Oregon's feed rolls monthly.

Data & fair use

All data comes from official state open-data portals (Socrata SODA APIs) that exist precisely for this kind of programmatic access, fetched with paging, backoff and polite pacing. Records are public business filings; the actor deliberately emits no officer/member personal data.
