Authentication

Send the API key either as a header or as a query parameter. The header is preferred; the query parameter exists for cases where a header cannot be set, such as opening a URL directly in a browser.

Authorization: required header

The API key on its own. Do not prefix it with Bearer or any other word.

Example Authorization: YOUR_API_KEY

token: optional query parameter

The API key, appended to the URL. Use this only when a header is not possible.

Request body

A JSON object. Content-Type must be application/json.

query: required string

The search expression in Lucene syntax. Every field listed under Searchable fields can be used, combined with AND, OR, NOT, ranges and wildcards.

Example item4_02:* AND filedAt:[2022-01-01 TO 2022-12-31]

from: string, Maximum 10000

Index of the first result to return, used for pagination. Increase it by the value of size to page through results. A query returns at most 10000 results, so narrow the search with a filedAt range when more disclosures match.

Default "0"

size: string, Maximum 50

Number of disclosures to return in one response.

Default "50"

sort: array of object

Sort order. Each item maps one field to an order object, for example [{ "filedAt": { "order": "desc" } }].

Default [{ "filedAt": { "order": "desc" } }]

order: string

Either asc or desc.
