`search_companies`

Find companies in Sales Navigator through a shared seat, by industry, place, size and recent signals.

This action only reads. It changes nothing, so it is safe to try. It is part of the Agent plan.

What you give it

Input	What it is	Where to get it
`industries` optional	A list (text). Company industries, e.g. ["Software","Financial Services"].	You write it.
`locations` optional	A list (text). Company HQ locations, e.g. ["United States"].	You write it.
`headcounts` optional	A list (text). Company size bands. Valid: self-employed, 1-10, 11-50, 51-200, 201-500, 501-1000, 1001-5000, 5001-10000, 10001+.	You write it.
`hiring` optional	True or false. Only companies with open job posts right now (hiring signal).	You write it.

`minRevenueMillions` optional	A number. Minimum annual revenue in millions (e.g. 10 = $10M+). LinkedIn uses fixed brackets (0, 0.2, 1, 2.5, 5, 10, 20, 50, 100, 500, 1000); other values widen to the nearest one. Revenue is LinkedIn's estimate — companies without one are left out.	You write it.

What you get back

When it worked, the answer is { "ok": true, "result": { … } }. Inside result:

`returned`
`source`
`filtersApplied`
`warnings`
`companies`
`note`

A field that does not apply to an answer is left out, or is null.

When it did not work, the answer is { "ok": false, "error": "…", "message": "…" }. What each error means.

Good to know

The total is totalCompanies; with recentFunding and recentLeadershipChange both true it is totalBySignal and withBothSignals instead.
There is no next page: narrow the filters.
