# Connecticut UCC Liens
> Every UCC and lien filing with the Connecticut Secretary of the State that is in force or ended within the last year, about 437,000 liens: search the names of debtors and secured parties, filter by status, lien type and filing date, and read one lien with every filing and the parties each lists, by any of its filing numbers.
The Connecticut Secretary of the State records the liens filed against
Connecticut businesses and people: UCC financing statements that secure a loan
or a lease on a debtor's assets, and municipal, federal tax, labor, vessel and
judgment liens. The register carries every lien that is in force, and every one
that lapsed, was released or was terminated within the last year. Each lien
comes whole: its status, type and lapse date, and every filing with the debtors
and secured parties that filing lists and a copy of the filing's own document. Whether it is still in force is computed
each time you ask. Brought up to date daily.
The whole source, organized and ready to query: every endpoint on this page answers in milliseconds. Every response carries `as_of`: how current the data is. [How datasets work](/datasets).
## Search liens
`POST /us/ct-ucc/liens-search/v1` Dataset
Searches the liens by any combination of party name, status, lien type and
filing date.

```bash theme={"dark"}
curl https://api.croma.run/us/ct-ucc/liens-search/v1 \
-H "Authorization: Bearer $CROMA_API_KEY" \
-H "Content-Type: application/json" \
-d '{ "query": "citizens bank" }'
```
Returns `as_of`, the applied filters, `total`, `page`, `per_page`, `total_pages`, `count` and `liens[]`, newest first.
Every lien carries `id`, `lien_number`, `status` (`ACTIVE`, `RELEASED` or `TERMINATED`), `lien_type` (e.g. `OFS` for a financing statement, `MUNICIPAL`, `IRS`, `LABOR`, `DEPT REV SERVS`, `VESSEL`, `JUDGMENT`), `lapse_date` (`9999-12-31` when it does not lapse), `filed_date`, `last_filed_date`, `filing_numbers`, `debtor_names`, `secured_party_names`, `in_force` and `filings[]`, oldest first. Each filing carries `filing_number`, `filing_type` (e.g. `ORIG FIN STMT`, `AMENDMENT`, `CONTINUATION`, `RELEASE`, `ASSIGNMENT`), `accepted_date`, `pages`, `volume`, `start_page`, the `debtors[]` and `secured_parties[]` it lists, each `{ name, business_name, prefix, first_name, middle_name, last_name, suffix, address: { street_1, street_2, city, state, zip } }`, and its document: `document_url` (Croma's copy of the filing's PDF, byte for byte), `source_document_url` (the Secretary's own link) and `document_name` (the name the Secretary gave the file), null until the copy is made or when the Secretary publishes none. Debtors include people, with their addresses, as the filings list them.
`in_force` is computed by Croma when the response is served: true while the lien is `ACTIVE` and not past its lapse date, false otherwise. The register carries some liens as `ACTIVE` after their lapse date.
## One lien, whole
`POST /us/ct-ucc/lien/v1` Dataset

-d '{ "filing_number": "0005046935" }'
