## 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 `crdNumber:105129`

from: string, Maximum 10000

Index of the first result to return, used for pagination. Increment by the value of size to page through results. Narrow the query by date range to reach beyond the cap.

Default `"0"`

size: string, Maximum 50

Number of cover pages to return in one response.

Default `"50"`

sort: array of object

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

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

order: string

Either asc or desc.
