# List companies for cross-sell by license and usage

As a Reseller you list or export companies with license details (license type, license limit, user count, renewal date, tags) to identify cross-sell or upsell opportunities. Use a credential with Client Role = **Reseller**. Use the same company search endpoint; filter or sort by license type, usage, or renewal date to find candidates. Request body: see Endpoints → **Company** for filter and sort options.

***

## POST /api/companies/search

Returns a paginated list of companies with license details. Use **`filter`** to narrow by license type, renewal date, or other fields if the API supports them. Use **`orderBy`** (e.g. `RenewalDate`, `CreateTime`, or license-related fields) and **`ascending`** to sort. Each item includes license limit, user count, renewal date, and related fields for cross-sell analysis.

## POST /api/companies/search/export

Exports the same list to CSV or Excel for analysis in a spreadsheet or BI tool. Use the same filter and sort as in search so the export matches your cross-sell criteria.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://doc.keepnetlabs.com/api-reference/reseller/billing/list-companies-for-cross-sell-license-and-usage.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
