US State Business Entities — Colorado & Connecticut Registry

Get the business entities registered in Colorado and Connecticut from the two states' official open-data portals: the Colorado Department of State's "Business Entities in Colorado" (data.colorado.gov) and the Connecticut Secretary of the State's "Connecticut Business Registry - Business Master" (data.ct.gov). Both states publish these datasets as Public Domain. No account, no API key.

• Watch new registrations — LLCs, corporations, nonprofits, limited partnerships and LLPs formed or registered in a date range (both states update daily). Schedule the Actor daily or weekly with registeredFrom: "7 days ago".
• Search by part of the name, entity type, status, city or ZIP code.
• One row per entity: name, state ID, entity type, status (plus a common active / delinquent / inactive group), formation or registration date, dissolution date, city, state and 5-digit ZIP code, NAICS industry (Connecticut), and a link to the record on the state portal.
• Registered business entities only, no personal contact data. Registered agents, officers and members, e-mail addresses, street and mailing addresses, and Connecticut's owner survey answers (woman-, veteran-, minority-, LGBTQI- and disability-owned) are never requested from the portals, so they are never in the output. Sole proprietorships and trade names (DBAs) are not in these registers. Entity types whose registered names can be a person's own name are excluded: general partnerships (both states), Colorado corporations sole and "other foreign" entities (FO), and Connecticut records of the "Unknown" type — together about 0.3% of Colorado and 0.1% of Connecticut records.

Quick start — verified input

{
  "states": ["CO", "CT"],
  "maxItems": 100
}

Returns the newest 100 registrations across both states, newest first (4 requests, a few seconds). Running the Actor with an empty input {} does exactly the same.

Watch new Denver LLCs (verified):

{
  "states": ["CO"],
  "entityTypes": ["llc"],
  "cities": ["Denver"],
  "registeredFrom": "7 days ago",
  "maxItems": 1000
}

}

Input

Field	What to enter	Example
states	CO, CT or both (default).	["CT"]
nameKeywords	Text that must appear in the registered name, any case. Each entry is a phrase; several entries = any of them.	["dental", "acme holdings"]
entityTypes	llc, corporation (for-profit, incl. benefit corporations), benefit corporation, nonprofit, limited partnership, llp, lllp, partnership (any of these partnerships), cooperative, statutory trust, financial institution, insurance, water company — or a state's own code such as DLLC, FPC, DNC (Colorado) or LLC, Stock, Non-Stock (Connecticut). General partnerships, FO, CS and Unknown are never returned.	["llc", "corporation"]
statuses	active, delinquent, inactive, or a state's own status such as Good Standing, Voluntarily Dissolved (Colorado) or Forfeited (Connecticut). Empty = every status.	["active"]
registeredFrom / registeredTo	Formation or registration date range: YYYY-MM-DD, a month 2026-10, today, yesterday, 7 days ago.	"2026-10-01"
cities	City of the principal (Colorado) or business (Connecticut) address.	["Denver", "Hartford"]
zipCodes	5-digit ZIP codes or 3–4 digit prefixes.	["80202", "061"]
maxItems	Maximum rows (1–100,000), newest first across the selected states.	500
maxApiRequests	Hard cap on requests to the portals in one run (default 200). One request returns up to 1,000 rows.	50

Status groups: active = in good standing (Colorado "Good Standing" / "Exists"; Connecticut "Active" without a past-due report); delinquent = still exists but a report is past due or similar (Colorado "Delinquent", "Noncompliant"; Connecticut "Active" with sub-status such as "Annual report past due"); inactive = dissolved, withdrawn, revoked, merged, forfeited and similar. Use active and delinquent together for every entity that still exists.

Field notes:

• name — Colorado appends a status note to the names of many entities that are no longer in good standing (for example "Acme LLC, Dissolved September 30, 2025"). The note is removed from name; nameAsListed keeps the state's text, and for inactive entities the date fills dissolutionDate.
• registrationDate is the formation date of a domestic entity or the date a foreign (out-of-state) entity registered in the state. Colorado lists some future dates (filings with a delayed effective date); they come first when sorting newest first.
• domestic is false for a foreign entity registered in the state; jurisdictionOfFormation says where it was formed.
• The address is reduced to city, state or province, 5-digit ZIP code and country. ZIP+4 and non-US postal codes are not output. Both registers are typed in by filers: a city that looks like a street, a P.O. box or a contact line is left empty, and the same city can appear in several spellings (for example "COS" for Colorado Springs).
• naicsCode / naicsDescription are the industry codes Connecticut businesses give when they file (not every business gives one). Colorado has no industry field.
• sourceRecordUrl opens the full public record on the state portal (JSON). It is a link only — the Actor itself never reads the columns it does not output.
• The RUN_SUMMARY record in the key-value store shows, per state, the license read at the start of the run, when the state last updated the dataset, the requests and pages, rows withheld or not matching, and why a run stopped early (if it did).

Empty results?

• The name text is not part of any registered name. It is matched as typed (as a phrase, any case): "acme holdings" does not match "Acme Real Estate Holdings" — use ["acme"] or two entries.
• The city is spelled differently in the register, or the ZIP code is outside the selected states.
• registeredFrom is in the future or the range is very short; Colorado's daily update can lag a day behind Connecticut's.
• The filters exclude everything together, or a filter exists in one state only (e.g. lllp is Colorado only, statutory trust Connecticut only — the other state is then skipped with a warning).

How it works

The Actor calls only the public Socrata API of the two portals: one metadata request per state (the run checks that the license still reads "Public Domain" and skips a state whose license has changed) and pages of up to 1,000 rows of the business dataset, ordered by date. Requests are sent one at a time, at least 1.2 seconds apart (the portals' robots.txt asks for 1 second), anonymously and with a hard request budget. Datacenter access works directly; no proxy is needed. If one state's portal fails, the other state's rows are still delivered and the run is marked incomplete.
