Common fields to autocomplete
| Field | Why you would use it |
|---|
basic_info.industries | Find exact industry labels before building industry filters. |
basic_info.name | Surface company names matching a partial string. |
basic_info.markets | Discover indexed market labels (e.g. NASDAQ, NYSE). |
basic_info.employee_count_range | List the canonical employee-count bucket labels. |
taxonomy.professional_network_industry | Match primary industry values used in company search. |
taxonomy.professional_network_specialities | Discover specialty tags used by the dataset. |
taxonomy.categories | List the high-level category tags used by the dataset. |
locations.country | Discover country values used by the indexed dataset. |

revenue.public_markets.fiscal_year_end | Closed enum: returns the twelve calendar months in chronological order. |
The field parameter accepts a broader set than this table — the table
highlights the most useful fields for building filter dropdowns. For the
full live allowlist, send a deliberately invalid field and read the
Valid fields list returned in the 400 error. The shape of that error
message is for debugging only and may change without notice.
revenue.public_markets.fiscal_year_end is a closed-enum static
field — an empty query returns the twelve months
(January…December) in chronological order without any backend
lookup. Use it to populate a static fiscal-year-end dropdown without an
extra round-trip.
Supported filter operators
=, !=, <, =<, >, =>, in, not_in, contains.
The operators >= and <= are not supported. Use => and =<
instead.
Common errors and edge cases
If no values match your query, the API returns an empty array:
If you send an unsupported field name, the API returns a 400 with the list
of valid fields:
{
"error": {
"type": "invalid_request",
"message": "Field 'invalid_field' is not supported on scope 'company'. Valid fields: basic_info.company_type, basic_info.employee_count_range, basic_info.industries, basic_info.markets, basic_info.name, basic_info.primary_domain, ...",
"metadata": []
}
}
