Delaware

Every business entity on file with the Delaware Division of Corporations: corporations, limited liability companies, limited partnerships, statutory trusts and partnerships, domestic and foreign, active and inactive. Delaware is where most US startups, venture funds and public companies are formed, so this is the registry a diligence, KYC or counterparty check starts from. Two steps: search a name to get file numbers, then look one up for the Division’s free record, with the formation date, the kind and type of entity, the state of formation and the registered agent.

Search entities

POST /us/delaware/entities-search/v1 Searches the registry by entity name and returns up to 50 matches with their file numbers.

Field	Type	Notes
`query`	string	Required. The entity name, or its words, e.g. `GOOGLE LLC`. Case does not matter; `AND` and `&` are equivalent.
`exact`	boolean	Optional. `true` to return only entities whose name is exactly `query`. Default `false`.

curl https://api.croma.run/us/delaware/entities-search/v1 \
  -H "Authorization: Bearer $CROMA_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{ "query": "GOOGLE LLC", "exact": true }'

Returns query and exact (echoed), count, truncated and entities[], each { file_number, name }, alphabetical by name. Pass a file_number to the lookup below for the full record.

The Division lists at most 50 matches per search and does not page further. When more entities match, truncated is true and the first 50 are returned: refine the query, or pass exact: true with the full name.

Entity by file number

POST /us/delaware/entity/v1 Resolves one entity by its file number and returns the Division’s record.

Field	Type	Notes
`file_number`	string	Required. The Division’s file number, digits only, e.g. `3582691`, as returned by the search.

curl https://api.croma.run/us/delaware/entity/v1 \
  -H "Authorization: Bearer $CROMA_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{ "file_number": "3582691" }'

Returns found, file_number, entity (null when not found) and checked_at. The record carries file_number (the Division’s key), name, filed_on (yyyy-mm-dd, the incorporation or formation date the Division prints), entity_kind (Corporation, Limited Liability Company, Limited Partnership, Statutory Trust, Partnership, Registered Series, …), entity_type (General, Bank, Benefit Corporation, Closed Corp, Exempt, Series, …), residency (domestic or foreign), state (the state of formation as the Division prints it, e.g. DELAWARE) and registered_agent ({ name, address, city, county, state, postal_code, phone }, or null). Empty fields are null. This is the Division’s free record. It is not a statement of good standing: status, franchise tax and filing history are not part of it.

A file number the Division does not carry returns found: false with HTTP 200, not an error.
